  1. Biocompatibility Survey Michael DeSalvio, Kevin Ip, John Chi, Khine Win, Michael Nguyen

  2. Polyurethane • Properties • Cheap • Durable • Strong • High stress and strain (More tear-resistant than rubber) • Uses • Tubing: catheters, dialysis, sutures, artificial heart valves • Temporary implants: gastric bubbles • Medical bedding (foam) • Surgical drapes • Wound dressing (hydrogels) • Polyurethane implants (non-US) • Condoms • Electrical Insulation

  3. Polyurethane Catheter

  4. Hydrogels • Biocompatible gel • Provides a moist environment to promote healing • Promotes absorption and debriding of necrotic tissue • Polymer based sheet to cover wounds and deliver drugs via a capsule design • Reduce appearance of scars

  5. Hydrogel Contact • Traditional contacts are not permeable to O2 • Water inside the contact transfers O2 from the outside to the eye • Silicon hydrogel contacts are permeable to O2 • Up to 5x more O2 can pass through • Can be worn for up to 30 days w/o removal

  6. Stainless Steel Inflated Balloon • Properties • Corrosion- and Heat- Resistant • Durable and easily sterilized • Inexpensive • Easily manipulated to desired shape • Inert, nice finish • Uses • Implants (crowns, joints) • Medical Instrument, (Scalpel, needles, ) • Bedpans, Trays, Carts.. • Tubing, cables • Bone Plates, Screw, Rods Expanded Stent
