摘要： An improved surgical clip having first and second leg members joined at their proximal ends by resilient hinge means and terminating at their distal ends in latch means. Each leg member has an outer surface and a clamping inner surface. The outer surface of each leg member is configured to be accepted by the jaws of a clip applier. The improvement in the clip design specifically relates to the design of the clamping inner surface of each leg member of the clip. The clamping inner surface of the first leg member has a convex radius of curvature extending transversely across at least a portion of the width of the first leg member, and the clamping inner surface of the second leg member has a concave radius of curvature extending transversely across at least a portion of the width of the second leg member. The radius of curvature of the clamping inner surface of the first leg member is smaller than, and complementary to, the radius of curvature of the clamping inner surface of the second leg member.

摘要： A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners and is self-contained whereby a fastener is delivered and placed all from inside a vessel. The fasteners are self-forming whereby they do not need an anvil to be formed. Anchor elements are operated from outside the patient's body to cinch a prosthesis to an anchoring cuff of the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. Fasteners are placed and formed whereby fasteners are located continuously throughout the entire circumference of the cuff. A minimally invasive surgical method is disclosed, and a method and tool are disclosed for repairing abdominal aortic aneurysms in a minimally invasive manner. Fasteners that are permanently deformed during the process of attaching the cuff are disclosed as are fasteners that are not permanently deformed during the attaching process.

摘要： A method for inserting an instrument through a natural orifice. The instrument has a low profile orientation and a deployed orientation which is larger than the size of the natural orifice through which it is to be inserted. The method is achieved by coupling the instrument to an endoscope and placing the instrument in its low profile orientation, insetting the endoscope and the instrument through a natural orifice to a target position within a body while the instrument is in its low profile orientation, actuating the instrument to it is deployed orientation, and returning the instrument to its low profile orientation and withdrawing the instrument from the body through the natural orifice.

摘要： Methods and devices are provided for attaching one or more ancillary devices to an endoscope. The ancillary device can be any device that is used in conjunction with endoscopic procedures, such as, by way of non-limiting example, an accessory channel, tube, or sleeve, an indwelling tube or feeding tube, and surgical tools such as graspers, snares, etc. The ancillary device(s) can be positioned adjacent to and along side an external surface of an insertion portion of an endoscope for inserting into a body lumen, and one or more attachment devices can be used to mate the ancillary device(s) to the endoscope at one or more attachment locations. In use, the attachment device(s) will allow the ancillary device to move in coordination with the endoscope, thus allowing the endoscope and the ancillary device(s) to be introduced and guided through a tortuous pathway. In certain exemplary embodiments, the attachment device(s) can be configured to prevent radial movement, i.e., twisting, of the ancillary device relative to the endoscope, yet allow axial sliding of the ancillary device relative to the endoscope.

摘要： A surgical stapler having a selectively bendable end effector is provided. A staple holding jaw of the end effector is coupled to another jaw for grasping tissue to be stapled. The stapler can adapted to drive staples into tissue having a pattern conforming with the selected shape of the end effector. In particular, the end effector can be adapted to drive staples in a linear pattern when the end effector orients staples in a substantially linear configuration. The end effector can also be adapted to drive staples in a non linear pattern when the end effector orients staples in a non linear configuration. Methods of stapling tissue with a stapler having a bendable end effector are also discussed.
