Catheter Design

project definition
Project Definition
  • Objective: Determine a new design of a catheter that will increase control and maneuvering
  • Main Issues: Decrease use of vessels walls, increase speed of insertion, efficiently moving the device through the body
arteries to aneurysms
Arteries to Aneurysms
  • Insertion in the femoral artery leads up to the carotid artery
  • Three main parts of the carotid artery: common, internal, and external
  • Extreme degree of branching and curving
arteries to aneurysms continued
Arteries to Aneurysms continued
  • Carotid artery helps lead to aneurysm
  • Forms bubble in vessel
  • Blood is blocked from vessel with embolization and coil.
  • Catheter procedure used for embolization and coils
current status
Current Status
  • Prove using stitches will:
    • reduce effects of drag
    • induce curving
    • increase travel
key issues
Key Issues
  • Stitches can not catch on vessel walls
  • Length of stitching
  • Biocompatibility
  • Levitation of catheter in artery
  • Configuration
  • Control of rotation
  • Keeping catheter in laminar profile
future work
Future Work
  • Determine stitching to avoid catching on vessel wall through fluid dynamics.
  • Illustrate the effects of stitching on the flow and curvature of the catheter.
