DELIVERY SYSEMS FOR EMBOLIC FILTER DEVICES
First Claim
1. A system for delivering a filter device within a body vessel, comprising:
- a guide wire having a proximal end and a distal end; and
a sheath having a proximal end and a distal end and including a first lumen for receiving the filter device and a second lumen for receiving the guide wire therethrough, the filter device and sheath being moveable along the guide wire for positioning the filter device within the body vessel, the sheath being retractable over the filter device for deploying the filter device within the body vessel for deployment.

Abstract
A delivery system for an expandable filter device includes a dual lumen delivery sheath which has a lumen for receiving the expandable filter device and a lumen for receiving a primary guide wire. The primary guide wire is utilized to place the delivery sheath and expandable filter into the desired region of the patient'"'"'s vasculature via an over-the-wire or rapid-exchange arrangement. The delivery sheath can be protracted over the expandable filter device to allow the filter to be deployed within the patient'"'"'s vasculature at the desired location. The delivery system can be embodied in an alternative design in which the primary guide wire extends through a guide wire lumen located in an obturator which forms part of the expandable filter device. Again, the primary guide wire is utilized to maneuver the filter device into the desired area via an over-the-wire arrangement. A slit extending longitudinally along the length of the sheath facilitates the removal of the guide wire and delivery sheath from the patient'"'"'s vasculature.

22. A system for delivering a filter device within a body vessel, comprising:
-
a guide wire having a proximal end and a distal end; a filter device moveable between a collapsed position and an expanded position which includes an obturator located at the distal end of the filter device, the filter device being attached to the guide wire near its distal end; and a guide wire lumen extending through the obturator which is adapted to receive a second guide wire used to deliver the filter device into the body vessel utilizing an over-the-wire technique.
