摘要： A surgical instrument for cutting and grasping tissue comprising a handle assembly, an elongated member and first and second jaws. A first movable member moves the second jaw in a first direction about a first pivot axis in a grasping action and a second movable member moves the second jaw in a second direction different than the first direction and about a second pivot axis in a cutting action. A switch is positioned at the proximal portion of the instrument and a selecting member is actuated by movement of the switch, the selecting member movable between a first position to enable movement of the second jaw in the first direction and prohibit movement in the second direction and a second position to enable movement of the second jaw in the second direction and prohibit movement in the first direction.

摘要： The present invention provides a valve configured for insertion on the proximal and distal sides of a heart valve annulus to replace the heart valve of a patient. The valve comprises a first substantially annular portion adapted to be positioned on a proximal side of the annulus of a patient and a second substantially annular portion adapted to be positioned on a distal side of the annulus of a patient, wherein at least one of the first and second substantially annular portions is movable towards the other portion to a clamped position to clamp around the annulus. The second portion has a flow restricting portion extending therefrom and is movable between a first position to permit the flow of blood and a second position to restrict the flow of blood. In one embodiment, the valve has a suture joining the first and second portions to draw the first and second portions into closer proximity and a cinch member to secure the suture to maintain the first and second portions in the clamped position. In another embodiment, the first and second portions are connected by a first segment which biases the first and second portions toward the clamped position.

摘要： An elongated support dimensioned and configured for implantation in a blood vessel. The support has two axially spaced apart portions, which may be in the form of an expandable crown or a similar structure. At least one linking member connects the two portions to one another. A valve membrane is supported between the axially spaced apart portions. The valve membrane is adapted and configured for movement between a first position in which blood flow through the support is permitted and a second position in which blood flow through the support is inhibited.

摘要： A tissue retaining ring for use with a plurality of surgical fasteners mounted within a disposable loading unit utilized during a vascular anastomosis inlcudes a genrally circular, semi-pliable material having a series of alternating loops and arcuate portions. Each of the loops defines an aperture therein which is dimensioned to receive a distal end of one of the plurality of surgical fasteners. When the instrument is fired, the surgical fasteners are simultaneously deformed through the tissue ring and through the tissue. The tissue retaining ring holds the tissue in place along the surgical fastener and reduces the chances of tissue slippage after deformation.

摘要： Apparatus and method for surgery is disclosed which includes a retractor having a substantially planar base defining an opening for overlying an operative site on a patient, and at least one retractor blade slidably mounted to the base. The base is positioned on the patient such that the opening therein overlies the operative site. The operative site is percutaneously accessed, and obstructing tissue is retracted by engaging the tissue with the retractor blade. A surgical instrument is provided which is engageable with the base and operable at the operative site through the opening in the base. A surgical procedure is carried out through the opening in the base with the surgical instrument.

摘要： The present application provides an arterial cannula system for transporting blood from an extracorporeal pump to a patient's femoral artery and aorta comprising first and second cannula portions. The first cannula portion has a proximal portion, a distal portion, and an intermediate portion and is configured for insertion through the femoral artery. It includes a first lumen extending from the proximal portion to the distal portion to deliver cardioplegic fluid, a second lumen communicating with an expandable occluding member at the distal end portion to inflate the occluding member to occlude blood flow, and a third lumen extending from the proximal portion to the intermediate portion to transport blood from the extracorporeal pump to the femoral artery. The second cannula portion is configured for insertion into the subclavian artery so that an opening in the distal portion is in communication with the aorta. A lumen extending through the second cannula portion is in communication with the opening to transport blood from the extracorporeal pump to the aorta.
