    摘要： In a first embodiment of a system for treating diseased bowel, a pair of incisions are formed on opposite ends of a diseased section of bowel. A tubular bypass implant is positioned in the bowel such that its ends are anchored within the bowel and such that an intermediate section of the implant is positioned external to the bowel such that bowel contents flow through the implant and thus around the diseased bowel section. In a second embodiment, the diseased section of bowel is removed and a system is implanted for joining limbs of the resected bowel together to form an anastomosis. In the preferred anastomosis system, the limbs of the resected bowel are positioned between a tubular sleeve extending through the bowel and a tubular cuff positioned around the bowel.

    摘要： In a system and method for performing a treatment within a body cavity, an elongate cannula is provided having one or more distally positioned expandable elements. An incision is formed in body tissue to gain access to a body cavity. A distal portion of the cannula is extended through the opening and into the body cavity. The expandable element is expanded within the body cavity. During expansion, a portion of the expandable contacts tissue or structures within the body cavity, such that the expansion causes the distal portion of the cannula to deflect generally away from the tissue or structures.

    摘要： Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity, manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach. In an alternative embodiment, an expansion structure on the distal end of the elongate portion expands and/or contracts the medical implant to facilitate positioning.
