Abstract

A filter disposed at the distal end of an elongate guidewire. Catheters are provided for delivering the filter to, and retrieving the filter from, a treatment site. The catheters can be over-the-wire or single operator exchange. The catheters include a housing for receiving the filter therein. The housing has an atraumatic distal end.

Claims

1. A filter assembly, comprising:

a catheter including an elongate shaft having a proximal end and a distal end and a housing disposed at the distal end, the housing having a distal end;

an elongate wire extending at least in part through the catheter, the wire having a proximal end and a distal end; and

a filter connected to the wire proximate the distal end of the wire, and the filter being disposed in a position at least in part within the housing.
