Patent ID: 11617865

Abstract:
A suction catheter system is described with a suction extension interfaced with a guide catheter to form a continuous suction lumen extending through a portion of the guide catheter and through the suction extension. The suction extension can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. The suction extension can comprise a connecting section with a non-circular cross section for interfacing with the inner lumen of an engagement section of the guide catheter. Proximal fittings attached to the guide catheter can facilitate safe removal of the catheter system from the patient by allowing for the removal of some or all of a tubular extension of the suction extension from the guide catheter behind a hemostatic seal. The fittings can include a docking manifold that can dock the connection suction of the suction extension to allow removal of the suction extension from hemostatic isolation and clearing of clots from the suction extension without further fittings such that the cleared suction extension can be efficiently reinserted for additional use.
