  1. Hospitalists New options for DVT Treatment – Beyond the current standard of care 1

  2. Hospitalists are the frontline providers that diagnose and manage hospital-acquired VTEs in hospitalized patients. Nearly half of all venous thromboembolism (VTE) events occur during or soon after hospitalizations 2

  3. DVTis a blood clot that forms in a vein deep in the body What Is Deep Vein Thrombosis (DVT)? Most often occurs in the deep veins of the legs, either above the knee or below it The blood clot or part of it can break free (called embolism) and become lodged in the blood vessels of the lung, causing pulmonary embolism (PE) 3

  4. VTE: A Major Source of Mortality and Morbidity Over 600,000 patients diagnosed with DVT annually in the US alone Huge Costs and Morbidity Over 200,000deaths per year due to PE annually in the U.S. alone. Recurrence of DVT, post-thrombotic syndrome and chronic PE / PAH are long term sequelae More than HIV, MVAs & Breast Cancer combined 10% of Hospital Deathsmost common preventable death 4

  5. DVT Development Risks Several studies, including last year's Million Women Study, have shown that patients who have surgery for abdominal and pelvic cancers face a clot risk for at least a month. In the @RISTOS trial, 40% of surgical cancer patients' VTEs occurred after discharge, and the risk factors were the same, whether the clot appeared early or late. VTE prophylaxis has already made The Joint Commission's list of Patient Safety Goals, which call for anticoagulation to be managed by protocol. Using unfractionated heparin and even low-molecular-weight heparin, we're going to have to have a guideline to manage those patients. 5

  6. DVT: What we know Venous thromboembolism (VTE) is manifested clinically by deep venous thrombosis (DVT) and pulmonary embolism (PE). DVT, usually of the lower extremity, nearly always precedes PE. The risk of VTE increases greatly after age 50. • Other Risk Factors • Age • Trauma • Immobilization, • Surgery • Anti-estrogen tamoxifen also increases the risk of VTE • Inherited conditions that increase risk (thrombophilia) usually present before age 40, although it is not unusual to see the first episode of VTE in a patient with factor V Leiden appear after total hip replacement at age 65 OccurrenceThe disease most often occurs in hospitalized patients, particularly those with cancer or following surgical procedures, but also occurs sporadically in the community. In both settings, multiple risk factors are usually present. 6

  7. Risk of DVT in Hospitalized Patients No prophylaxis + routine objective screening for DVT Heit – Mayo ClinProc 2001;76:1102

  8. VTE is a Disease of Hospitalized and Recently Hospitalized Patients 1000 100 Recently hospitalized Cases per 10,000 person-years 10 1 Hospitalized patients Community residents Heit – Mayo ClinProc 2001;76:1102

DVT and the risk our patients face: Endothelial Damage Stasis Hypercoagulability Age > 40 Immobility CHF Stroke Paralysis Spinal Cord injury Hyperviscosity Polycythemia Severe COPD Anesthesia Obesity Varicose Veins Cancer High estrogen states Inflammatory Bowel Nephrotic Syndrome Sepsis Smoking Pregnancy Thrombophilia Surgery Prior VTE Central lines Trauma Most hospitalized patients have at least one risk factor for DVT 10

  11. Hospital Performance for Pharmacologic Venous Thromboembolism Prophylaxis and Rate of Venous Thromboembolism: A Cohort Figure Legend: Flow Diagram of Patient Progress Through the 90-Day Observation Period -- ICU indicates intensive care unit; VTE, venous thromboembolism. JAMA Intern Med. 2014;174(10):1577-1584. doi:10.1001/jamainternmed.2014.3384 Studies continue to identify the risks showing the need for DVT awareness in the ICU 2015 American Medical Association.

  13. Associated Illnesses that are a Consequence of VTE events Chronic thromboembolic pulmonary hypertension Post thrombotic Syndrome Mean pulmonary artery pressure greater than 25 mm Hg that persists 6 months after PE 2-4% of patients after PE Calf swelling and skin pigmentation; venous ulceration in severe cases Up to 43% of patients develop PTS within 2 years Goldhaber SZ, Bounameaux H. Lancet. 2012 May 12; 379:1835-46

  14. Venous Thromboembolism (VTE) remains a major health problem In addition to the risk of sudden death • 30% of survivors develop recurrent VTE within 10 years • 28% of survivors develop venous stasis syndrome within 20 years

  15. DVT and the Risks DVT risk and prophylaxis in the hospitalized patient Physicians at UCSD use these checklists to assess all adult inpatients when they are admitted, transferred between units, or post-op 15

  16. DVT and the Risks DVT risk factors Physicians at UCSD use these checklists to assess all adult inpatients when they are admitted, transferred between units, or post-op 16

  17. DVT and Your Cancer Patient Patients with cancer who develop VTE are at higher risk of both recurrence and death than other patients with VTE. Because of improved treatment and longer survival, patients with cancer account for an increasing proportion of those with VTE. VTE can occur before cancer is evident, at the time of the cancer diagnosis and at any point in the clinical course of patients with known cancer. VTE is particularly likely to occur during intensive chemotherapy and as a complication of cancer surgery. For years, clinicians have been aware of so-called "warfarin failure"-the tendency to develop recurrent VTE despite an INR between 2.0 and 3.0-in patients with VTE and cancer. Recent clinical trials have shown that long-term LMWH in a treatment dose reduces the recurrence rate of VTE in cancer patients by 50% compared with warfarin (INR 2.0-3.0). 17

  18. Strategies to Improve Thromboprophylaxis Success • Excellent quality guidelines • National body endorsement • Hospital accreditation (JCAHO) • Pay for performance (CMS) • Localwritten policy (care pathway) for the hospital / program / patient care unit • Multidisciplinary team • Goals and Measures • Standardized risk assessment and order sets

  19. National Recommendations American College of Chest Physicians (ACCP) “We recommend that every hospital develop a formal strategy that addresses the prevention of thromboembolic complications.” 19

  20. The Real Question: Prompt diagnosis and treatment of deep vein thrombosis (DVT) is essential to decrease both the risk of recurrence and a potentially fatal pulmonary embolism (PE) What do we do with thosepatients that develop a DVT? 20

  21. In-Hospital DVT We can do better for these patients? Using multidisciplinary team approach Understanding the options for thrombus removal Setting a goal of quickly removing the thrombus Offering minimally invasive solutions Is Current in-hospital treatment adequate? Anticoagulation Compression Stockings 21

  22. Treating DVT Once It Has Occurred Interventional Treatment of DVT can help reduce the risk of complications, such as PE The current goals in treating DVT support: Stop the clot from progressing and getting larger Reduce the chance of having another clot develop Prevent the clot from breaking off in your vein and moving to your lungs 22

  23. Treating DVT Once It Has Occurred The best strategy once a DVT has been diagnosed is clot removal The option of “clot removal” Dissolving and/or Mechanical removal Restores flow decreases risk of clot Allows venous valves to return to normal function Can decrease long term anticoagulation 23

  24. A New Option For Venous Thrombus Removal New options exist for minimally invasive treatment to remove the venous clot • Infusion of clot busting medication to assist in removal • Followed by thrombus removal using a mechanical device to remove the clot from the vessel and body 24

  25. DVT Clot Removal We Believe We Can Efficiently remove the thrombus Provide quick restoration of venous flow Decrease risk of embolic complications Assist in restoring normal venous valve function 25

  26. DVT Clot Removal Interventional Treatment offers Patient's A minimally invasive procedure Potential to minimize treatment time Possibly eliminate or decrease dose and duration of thrombolytic Potential for quick resolution of signs and symptoms Improved short-term & long-term outcomes 26

  27. An option for DVT thrombus Removal ANGIOJET™ ULTRA Thrombectomy System MECHANISM OF ACTION The AngioJet Ultra Console monitors and controls the system. The Console energizes the pump which sends pressurized saline to the catheter tip. Saline Jets travel backwards to create a low pressure zone causing a vacuum effect. 4. Thrombus is drawn into the in-flow windows and the jets push the thrombus back down the catheter. 5. Thrombus is evacuated from the body and into the collection bag. 27

  28. There is an indication and data behind thrombus removal Outcomes – Interventional Approach To Remove DVT Thrombus • 97%had venographic improvement • 84%had freedom from re-thrombosis at 1 year Improved quality of life score for mental and physical baseline out to 1 year Patients treated: 67% acute, 19% sub-acute and 14% Chronic thrombus age Bleeding complication rate was 4.5%, however not related to the use of AngioJet The PEARL Registry looked at 371 DVT patients treated using an interventional approach 28

  29. There is an indication and data behind thrombus removal PEARL Registry data demonstrates that mechanical thrombectomy treatment of DVT is safe and effective and can potentially reduce the need for concomitant catheter directed lytic and intensive care stay. The PEARL Registry looked at 371 DVT patients treated using an interventional approach 29

  30. There Is An Indication And Data Behind Thrombus Removal Using an interventional approach for DVT results showed Overall, 75% cases completed in < 24 hours 38% of DVT treatment times were completed in < 6 hours 87% had two or less interventional treatments The PEARL Registry looked at 371 DVT patients treated using an interventional approach 30

  31. Moving Forward Consults available for your patients that have developed a DVT Offer a multidisciplinary team approach to in-hospital DVT Create best practice model Develop treatment pathways to benefit patients for quicker recovery Reduce the potential risks for those that develop DVT Decrease hospital stay and cost associated with DVT Potential to improve short and long term outcomes 31

  34. Solent Catheters combined w/consoleCAUTION: Federal law (USA) restricts this device to sale by or on the order of a physician. Rx only. Prior to use, please see the complete “Instructions for Use” for more information on Indications, Contraindications, Warnings, Precautions, Adverse Events, and Operator’s Instructions.INDICATIONS AND USAGE The AngioJet SOLENT proxi & omni Thrombectomy Sets are intended for use with the AngioJet Ultra Console to break apart and remove thrombus from: • upper and lower extremity peripheral arteries ≥ 3.0mm in diameter, • upper extremity peripheral veins ≥ 3.0mm in diameter, • ileofemoral and lower extremity veins ≥ 3.0mm in diameter, • A-V access conduits ≥ 3.0mm in diameter and • for use with the AngioJet Ultra Power Pulse technique for the control and selective infusion of physician specified fluids, including thrombolytic agents, into the peripheral vascular system. The AngioJet SOLENT dista Thrombectomy Set is intended for use with the AngioJet Ultra Console to break apart and remove thrombus from: • upper and lower extremity peripheral arteries and • for use with the AngioJet Ultra Power Pulse technique for the control and selective infusion of physician specified fluids, including thrombolytic agents, into the peripheral vascular system. The minimum vessel diameter for each Thrombectomy Set model is listed in Table 1 (in the IFU).CONTRAINDICATIONS Do not use the catheter in patients: • Who are contraindicated for endovascular procedures • Who cannot tolerate contrast media • In whom the lesion cannot be accessed with the guide wire WARNINGS AND PRECAUTIONS • The Thrombectomy Set has not been evaluated for treatment of pulmonary embolism. There are reports of serious adverse events, including death, associated with cases where the catheter was used in treatment of pulmonary embolism. • The Thrombectomy Set has not been evaluated for use in the carotid or cerebral vasculature. • The Thrombectomy Set has not been evaluated for use in the coronary vasculature (unless accompanied by a separate coronary IFU). • Operation of the catheter may cause embolization of some thrombus and/or thrombotic particulate debris. Debris embolization may cause distal vessel occlusion, which may further result in hypoperfusion or tissue necrosis. • Cardiac arrhythmias during catheter operation have been reported in a small number of patients. Cardiac rhythm should be monitored during catheter use and appropriate management, such as temporary pacing, be employed, if needed. • Use of the catheter may cause a vessel dissection or perforation. • Do not use the AngioJet Ultra System in patients who have a nonhealed injury due to recent mechanical intervention, in the vessel to be treated, to avoid further injury, dissection, or hemorrhage. • Do not use the Thrombectomy Set in vessels smaller than minimum vessel diameter for each Thrombectomy Set model as listed in Table 1 (in the IFU); such use may increase risk of vessel injury. • Systemic heparinization is advisable to avoid pericatheterization thrombus and acute rethrombosis. This is in addition to the heparin added to the saline supply bag. • Operation of the AngioJet System causes transient hemolysis which may manifest as hemoglobinuria. Table 1 (in the IFU) lists maximum recommended run times in a flowing blood field and total operating time for each Thrombectomy Set. Evaluate the patient’s risk tolerance for hemoglobinemia and related sequelae prior to the procedure. Consider hydration prior to, during, and after the procedure as appropriate to the patient’s overall medical condition. • Large thrombus burdens in peripheral veins and other vessels may result in significant hemoglobinemia which should be monitored to manage possible renal, pancreatic, or other adverse events. • Monitor thrombotic debris/fluid flow exiting the Thrombectomy Set via the waste tubing during use. If blood is not visible in the waste tubing during AngioJet Ultra System activation, the catheter may be occlusive within the vessel; verify catheter position, vessel diameter and thrombus status. Operation under occlusive conditions may increase risk of vessel injury. • Do not exchange the guide wire. Do not retract the guide wire into the catheter during operation. The guide wire should extend at least 3 cm past the catheter tip at all times. If retraction of the guide wire into the Thrombectomy Set occurs, it may be necessary to remove both the Thrombectomy Set and the guide wire from the patient in order to re-load the catheter over the guide wire. (Dista only) • Use of a J-tip guide wire is not recommended as it is possible for the tip of the guide wire to exit through a side window on the distal end of the catheter. (Omni, Proxi only) • Do not pull the catheter against abnormal resistance. If increased resistance is felt when removing the catheter, remove the catheter together with the sheath or guide catheter as a unit to prevent possible tip separation. • If resistance is felt during the advancement of the Thrombectomy Set to lesion site, do not force or torque the catheter excessively as this may result in deformation of tip components and thereby degrade catheter performance. • Obstructing lesions that are difficult to cross with the catheter to access thrombus may be balloon dilated with low pressure (≤ 2 atm). Failure to pre-dilate difficult-to-cross lesions prior to catheter operation may result in vessel injury. • The potential for pulmonary thromboembolism should be carefully considered when the Thrombectomy Sets are used to break up and remove peripheral venous thrombus. . (Below is Omni, Proxi only) • Hand injection of standard contrast medium may be delivered through the thrombectomy catheter via the manifold port stopcock. Follow the steps to remove air from the catheter when delivering fluid through the catheter stopcock. • Fluids should be injected only under the direction of a physician and all solutions prepared according the manufacturer instructions. • The Thrombectomy Set waste lumen is rated for 50psi. Delivering a hand injection of contrast medium with excessive force can create injection pressures greater than 50psi, potentially causing leaks in the waste lumen of the catheter. • Do not use a power injector to deliver contrast medium through the catheter stopcock. Power injectors can deliver pressures greater than 50psi, potentially causing leaks in the waste lumen of the catheter. • Some fluids, such as contrast agents, can thicken in the catheter lumen and block proper catheter operation if left static too long. The catheter should be operated to clear the fluid within 15 minutes of injection. Console WARNINGS and PRECAUTIONS: • Use the AngioJet Ultra Console only with an AngioJet Ultra Thrombectomy Set. This Console will not operate with a previous model pump set and catheter. • Do not attempt to bypass any of the Console safety features. • If the catheter is removed from the patient and/or is inoperative, the waste tubing lumen, guide catheter, and sheath should be flushed with sterile, heparinized solution to avoid thrombus formation and maintain lumen patency. Reprime the catheter by submerging the tip in sterile, heparinized solution and operating it for at least 20 seconds before reintroduction to the patient. • Refer to the individual AngioJet Ultra Thrombectomy Set Information for Use manual for specific warnings and precautions. • Do not move the collection bag during catheter operation as this may cause a collection bag error. • Monitor thrombotic debris/fluid flow exiting the catheter through the waste tubing during use. If blood is not visible during console activation, the catheter may be occlusive within the vessel or the outflow lumen may be blocked. • Ensure adequate patient anticoagulation to prevent thrombus formation in outflow lumen. • Refer to individual Thrombectomy Set Instructions for Use manual for specific instructions regarding heparinization of the Thrombectomy Set. • The Console contains no user-serviceable parts. Refer service to qualified personnel. • Removal of outer covers may result in electrical shock. • This device may cause electromagnetic interference with other devices when in use. Do not place Console near sensitive equipment when operating. • Equipment not suitable for use in the presence of flammable anesthetic mixture with air or with oxygen or nitrous oxide. • To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth. • Where the “Trapping Zone Hazard for Fingers” symbol is displayed on the console, there exists a risk of trapping or pinching fingers during operation and care must be exercised to avoid injury. • Do not reposition or push the console from any point other than the handle designed for that purpose. A condition of overbalance or tipping may ensue. • The AngioJet Ultra Console should not be used adjacent to or stacked with other equipment, and if adjacent or stacked use is necessary, the AngioJet Ultra Console should be observed to verify normal operation in the configuration in which it will be used. • Portable and mobile RF communications equipment can affect MEDICAL ELECTRICAL EQUIPMENT. • The use of accessories and cables other than those specified, with the exception of accessories and cables sold by Bayer HealthCare as replacement parts for internal components, may result in increased EMISSIONS or decreased IMMUNITY of the Ultra Console. • MEDICAL ELECTRICAL EQUIPMENT needs special precautions regarding Electro-Magnetic Compatibility (EMC) and needs to be installed and put into service according to the EMC information provided in the tables provided in the IFU. ADVERSE EVENTS Potential adverse events which may be associated with use of the AngioJet Ultra Thrombectomy System are similar to those associated with other interventional procedures and include, but are not limited to: • abrupt closure of treated vessel • acute myocardial infarction • acute renal failure • bleeding from access site • cerebrovascular accident • death • dissection • embolization, proximal or distal • hematoma • hemolysis • hemorrhage, requiring transfusion • hypotension/hypertension • infection at the access site • pain • pancreatitis • perforation • pseudoaneurysm • reactions to contrast medium • thrombosis/occlusion • total occlusion of treated vessel • vascular aneurysm • vascular spasm • vessel wall or valve damage Final PEARL Data Aug 2013;Presented by Dr. Mark Garcia at CIRSE 2013; AngioJet, Solent, AVX, Power Pulse and Cross-Stream are trademarks of Boston Scientific. 34
