Abstract
A system for removing an obstruction from a blood vessel includes an obstruction engaging element and an expandable capture element. The capture element preferably has a flexible cover and an expandable support structure. The engaging element engages the obstruction and moves the obstruction into the capture element. The capture element protects the obstruction when the obstruction is moved into the catheter.
Claims6
A method of removing an obstruction from a blood vessel, comprising the steps of:
- providing a obstruction engaging element having a collapsed position and an expanded position, the obstruction engaging element having at least one filament, the filament being in a substantially straight configuration when collapsed;
- advancing the obstruction engaging element through a patient's vascular system to an obstruction with the obstruction engaging element in the collapsed position;
- and
- engaging the obstruction with the obstruction engaging element, the filament engaging the obstruction with a shape which extends from a proximal end toward a distal end, turns back toward the proximal end and again turns back and extends toward the distal end.
