  1. Cynthia Harmon Jarntip Pitayagulsarn Advisor: Ted Larson February 18. 2002 Catheter Design

  2. 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

  3. 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

  4. 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

  5. Current Status • Prove using stitches will: • reduce effects of drag • induce curving • increase travel

  6. 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

  7. 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.
