Abstract:

Endovascular filter () including a plurality of struts () with distal ends () adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (), the filter being adapted to be retrieved if desired. Strut distal ends () are coated with an antiproliferative agent () that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end () of the filter may also be so coated, or the entire filter.
