Abstract
A filter device for trapping embolic debris comprises a bag which is deployed by everting it from an end of a delivery catheter. After release from the catheter, with the assistance of a pusher member, the open end of the bag self-expands against the walls of a body lumen. In one method of removal after use, the device is withdrawn into catheter by pulling on a wire attached to the closed end of the bag.
