  1. Redesign of aDistal Protection FilterSandeep DevabhakthuniChenara JohnsonDaphne KontosPerry TiberioMentor: Dr. Ender Finol3/1/05

  2. Background • Atherosclerosis: Narrowing and hardening of carotid arterial walls due to plaque build-up • Could lead to stroke • Considered 3rd leading cause of death • Carotid Artery Stenting • Problem: Possible embolization in the brain resulting in a stoke. • Solution: Embolic Protection Devices

  3. Project Goals • Research distal protection filters currently on market to determine which features provide the best efficiency • Incorporate these best features into our redesign while adding new ones • Manufacture the prototype • Test prototype using flow loop system that simulates the carotid artery • Determine the efficiency of the redesign in capturing particles similar in size to embolic debris.

  4. Milestones/Timeline • Build prototype using Solidworks (Perry and Sandeep) – End of February • Order Materials (Daphne) –End of February • Manufacture prototype (All) – Middle of March • Test prototype in flow loop (All) – End of March • Perform statistical analysis on data (All) – Early April

  5. My Personal Focus • Research effects of filter pore size and consequences of reducing pore size – Done • Perry and I are building computerized prototype using Solidworks – Almost Done • Use COSMOSFloWorks to perform some preliminary testing to determine success of prototype – Currently Performing • As a group, we will build prototype using materials we ordered – Incomplete • As a group, we will run several tests on the prototype using the flow loop system at Carnegie Mellon – Incomplete

  6. SolidWorks Tentative Design

  7. Possible Problems • Manufacturing • Specifications of our design • Material • Attachment of struts • Testing • Actual prototype functioning the way we proposed
