Rapid exchange fluid jet thrombectomy device

摘要

A rapid exchange fluid jet thrombectomy device (14) for removal of thrombus or unwanted tissue debris from a vein, artery or the like. The device includes a semi-rigid intermediate tube (30) between a proximal (28) and a distal (32) exhaust tube which accommodates a guidewire tube (46) exit located along the catheter at less than one-half the length of the catheter measured from the catheter most distal point. Such a location of the guidewire is convenient for maneuvering and longitudinal advancement of the guidewire, as well as maneuvering and longitudinal advancement of the catheter by one practitioner.
