Abstract: A permanent or semipermanent hemodialysis access sheath that is placed in a central vein, secured and left in place for easy access by a removable hemodialysis catheter. The hemodialysis catheter has an adapter which secures the catheter to the sheath temporarily permitting the easy removal and replacement of the catheter as needed. The sheath has a side tube with a rotating flush valve. The sheath has a threaded opening which may be engaged by a threaded hub on the hemodialysis catheter for temporaraily securing the catheter to the sheath.

Abstract: A cardiopulmonary bypass system includes an aortic balloon cannula and a fluid flow cannula configured for connection to a cardiopulmonary bypass pump. The aortic balloon cannula includes an elongated tube device with first and second inflatable balloons mounted on the tube device and first and second lumen sized to communicate blood from the cardiopulmonary bypass pump to the patient's aorta. The cardiopulmonary bypass pump is configured to selectively deliver blood to the patient through the aortic balloon cannula and/or the fluid flow cannula at first, second and third temperatures.

Abstract: The disclosed appliance enables the rapid insertion of a tube around the nasal septum of a patient to form a harness onto which to secure a medical tube entering through the nasal passage. The appliance has a feed through arm having a first end angled to form a first handle member. A receiving arm, having a first end angled to form a second handle member and is attached to the feed arm by a swivel juncture. A fulcrum housing at the proximal end of the upper clamping member forms a swivel juncture to enable a lower clamping member, extending from the fulcrum housing to the second end of the receiving arm second end, to be moveable. The feed arm and receiving arm move in a scissor like manner on a first plane while the upper and lower clamping members move on a second plane, angled to the first plane.

Abstract: A method for the treatment of a stenosis or an occlusion in a blood vessel in which an occlusive device is first delivered and activated at a site distal to the occlusion to at least partially occlude the vessel. A therapy catheter is then introduced to treat the occlusion and a debris removal device is delivered to aspirate debris from the vessel. The present invention eliminates the need for a separate irrigation catheter and irrigation fluid which allows the procedure to be performed quickly and efficiently, and is especially useful in the removal of occlusion from saphenous vein graft, the coronary and carotid arteries, arteries above the aortic arch and vessels of similar size and pressure.

Abstract: A trocar sleeve for introducing instruments into gas filled body spaces including an insertion tube and a valve chamber disposed proximally on it with a duckbill valve of elastic material. The duck bill value has a tubular body extending coaxially with respect to the axis of the insertion tube. An end of the body directed towards the insertion tube has two flat oblique walls forming a ridge with a slit extending therein transverse to the axis of the tube. The tubular body is oversized in a direction transverse to the slit with respect to the internal size of the valve chamber in the uninstalled rest state.

Abstract: A syringe for vaginal irrigation is disclosed. This syringe is easily and effectively used for irrigating monstrous secretions from the vagina particularly during or after a menstruation, thus removing monstrous odor from the vagina and allowing the user to feel refreshed at the vagina in addition to keeping the vagina clean and sanitary. The syringe is comprised of an elastic barrel containing a vaginal irrigating solution, an L-shaped elbow pipe engaging with the externally-threaded mouth of the barrel, and a hollow vaginal insert engaging with the elbow pipe through a screw type engagement. This vaginal insert has a linear and tapered profile with the outside diameter of the insert being gradually reduced in a direction from its end around the elbow pipe to its distal end.
