Abstract

Improved methods and apparatus for capturing emboli and subsequently removing or immobilizing the captured emboli are described. Emboli can be captured within a blood vessel and can be withdrawn to a position exterior to the blood vessel. Some filters can remain within a blood vessel yet direct emboli to a position exterior to the blood vessel.
