Abstract: The general purpose of the present invention is to provide a catheter for removal of an organized embolic thrombus, preferably in conjunction with a distal occlusion balloon guidewire. The present invention consists of three main components including a capture/delivery sheath, a capture sleeve of mesh attached to a tube and a grasping mechanism attached to another tube which is central to the other components. Operative structures in the form of manifolds are connected to such components in order to manipulate and control the relative positions of the capture/delivery sheath, the capture sleeve and the grasping mechanism. An embolic thrombus is engaged by the deployable automatically expanding serrated fingers of a grasping mechanism in combination with a deployable automatically expanding mesh capture sleeve. The capture/delivery sheath is maneuvered to cause compression of the serrated fingers and of the mesh capture sleeve for subsequent removal of the embolic thrombus.

Abstract: A thrombectomy catheter system with occluder and method of using same for removal of tissue, such as thrombus and the like, from a vessel in the body. Multiple catheters and an occluder-bearing guidewire tube at a thrombus site provide for expandable deployment of a compliant occluder against the vasculature walls distal to the thrombus. The expanded occluder is maneuvered proximally to urge thrombus into close proximity with a retractable capture cone located distally on a capture catheter where the thrombus is dislodged, entrained, and broken into pieces by the action of a fluid jet emanator and then evacuated through the capture catheter.
