摘要： A transgastric instrument provides a sterile and repeatable pathway to and through a gastric wall for the purpose of facilitating endoscopic transgastric procedures. The instrument includes at least one guide tube having a proximal end and a distal end, the distal end being shaped and dimensioned for positioning adjacent a desired location along the gastric wall. The instrument also includes a fixation mechanism at the distal end of the guide tube for selectively securing the distal end of the guide tube at a desired location along the gastric wall. An otomy creation device circumferentially smaller than the guide tube extends through the guide tube, the otomy creation device including a distal end shaped and dimensioned for cutting and dilating the gastric wall.

摘要： A surgical instrument comprises a handle and an elongate shaft, and is operable to remove an anastomotic ring device from a patient. The elongate shaft houses a plurality of ring engaging fingers. Each of the fingers comprises sheath housing a wire having a hook at its distal end. Each hook may be advanced beyond the distal end of a respective sheath to engage petals on an anastomotic ring device. Subsequent proximal retraction of the hooks secures the anastomotic ring device to the ring engaging fingers. With the anastomotic ring device secured to the ring engaging fingers, the fingers may be drawn together to collapse the anastomotic ring device from an actuated, hollow rivet-shaped configuration to an unactuated, cylindrically-shaped configuration. The surgical instrument may then contain the collapsed anastomotic ring device, thereby facilitating removal of the anastomotic ring device from the patient.

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.
