Endovascular guidewire filter and methods of use
First Claim
1. An endovascular filter, comprising:
- an elongate tubular member having a proximal end, a distal end, and a first proximal port proximal the distal end of the elongate tubular member;
a first flexible member having a proximal end that passes through the first proximal port of the elongate tubular member, and having a distal end fixed to the elongate tubular member at a first point distal the first proximal port, the first point being located at a circumferential position approximately 180°
from the first proximal port;
a filter disposed about the first flexible member, wherein the first flexible member is expanded by advancing distally the proximal end of the first flexible member.

Abstract
A filter device for temporary placement of a filter in an artery or vein is disclosed. The devices include (1) an elongate tubular member having a single or double side-wire loop, (2) an elongate member having a filter bonded to a circular rim joined by a plurality of tethers and an independently moveable tether, and (3) an elongate member having a parachute filter joined by a plurality of flexible struts. The filter conforms to the interior of a vessel wall when expanded and contracts to a consistent diameter without bunching when stowed. The filter devices may act as guidewires for guiding a therapeutic catheter to a region of interest within a vessel. Methods of using the filter device to entrap and remove embolic material from a vessel during endovascular procedures are also disclosed.
