    摘要： A device and method is provided for simulating a tubular body part having a mechanism for resisting fluid flow therethrough, such as the urethra. The device includes a housing having a having a first end, a second end, and a channel therethrough extending between an inlet at the first end of the housing and an outlet, and a plug member positioned within the channel and being sized and shaped to substantially occlude the channel at a predetermined location when a predetermined force is exerted on a first side thereof. The plug member is further movable within the channel so that, when a fluid force within the channel and exerted on a second opposite side of the plug member exceeds the predetermined force, the plug member no longer occludes the channel. The device further includes an adjustment member movably coupled to the housing and a compression member positioned within the channel in a compressed state so that a first end exerts pressure on the plug member and a second end exerts pressure on the adjustment member. The adjustment member is movable relative to the housing to thereby adjust the amount by which the compression member is compressed.

    摘要： A device for incising a blood vessel includes a handle having a longitudinal axis, a stationary blade having an upper surface and extending from the distal end of the handle at an angle out of line with respect to the longitudinal axis, and a moving blade having a distal portion that includes a leading edge. The moving blade is slidable with respect to the stationary blade. The distal portion of the moving blade is substantially aligned with the stationary blade. The moving blade has a first position and is movable to a second position to cut tissue disposed between the upper surface of the stationary blade and the leading edge of the moving blade.

    摘要： A method for providing at least partial bypass of the heart to supplement the pumping function of the heart to thereby enable the surgeon to perform various surgical procedures thereon includes providing a circulatory assist system having a portable extracorporeal axial flow pump with a pump housing, a rotating pumping member disposed in the pump housing and inlet and outlet cannulated tubes respectively connected to inlet and outlet ports of the pump housing, accessing the patient's left atrium of the heart with the inlet cannulated tube, accessing the aorta with the outlet cannulated tube, actuating the rotating pumping member to draw oxygenated blood from the left atrium of the heart through the lumen of the inlet cannulated tube and into the inlet port of the pump housing whereby the pumping member imparts mechanical energy to the oxygenated blood passing through the pump housing and directs the oxygenated blood through the outlet port and through the lumen of the outlet cannulated tube to be transferred by the aorta to the systemic arteries and permitting the right side of the heart to function whereby oxygen-depleted blood returning through the systemic veins to the right atrium is directed through the right ventricle to the patient's lungs for oxygenation and subsequent pulmonary circulation.

    摘要： A system for holding surgical fasteners each having a first anchor, a second anchor and a connector extending therebetween upwardly from the first and second anchors, and a method for loading the same into an applicator. The system includes a shuttle having first and second channels dimensioned to slidably receive therein the first and second anchors, and having first and second grooves respectively forming openings into the channels along a portion of a length of the channels. When the first and second anchors are received within the first and second channels, the connector of the surgical fastener extends out of the shuttle through the first and second grooves. The system also includes a cartridge having at least a first channel dimensioned to slidably receive the shuttle therein, and having a first projection extending into the first channel. When the shuttle and loaded fastener are received within the cartridge channel, the connector of the surgical fastener abuts the first projection to thereby limit movement of the fastener toward a distal end of the cartridge.
