Abstract:
An apparatus for the removal of build-up about an implanted catheter having an interior surface, an exterior surface and an open free end positioned within an individual's vascular system. The apparatus includes a delivery assembly storing a stripping coil. The delivery assembly includes a guide structure for guiding the stripping coil through the catheter to the free end of the catheter. The stripping coil is formed of a shape memory or super-elastic material, wherein the stripping coil is preformed to assume a shape wrapping about the outer surface of the catheter in a manner providing for the stripping of build-up from the outer surface of the catheter when the stripping coil is moved relative to the catheter.
A general-purpose stone extractor is provided for removing gallstones, calculi or foreign bodies from the biliary tree, urinary tract, blood vessels and the like. The stone extractor is configured to enable catcher wires to be extracted and retracted from an outer sheath near to a stone by operating a push handle member, an elastic spring being installed between a proximal end of the outer sheath and the push handle member.
Disclosed are manual thrombectomy devices having a plurality of elastic wires to form one or more cages and/or soft brushes connected to a lumen shaft along a longitudinal direction to easily detach thrombi from a vessel wall by manually rotating the lumen shaft right and left. And without any extra inflow tube, the manual thrombectomy device has an aspiration lumen and an inflow lumen in one body of the lumen shaft not only for preventing occurrence of a vacuum or a low pressure state in the blood vessel due to the thrombi aspiration during operation, but also for cleaning the vessel wall through outflow holes and for excreting the thrombi through aspiration holes.
