摘要： Medical devices and related methods for closing a perforation in a bodily wall The medical device generally includes a suture having opposing first and second ends and a set of visceral anchors. Each visceral anchor includes a crossbar having opposing ends and a suture slidably attached thereto. Each visceral anchor is passed through the bodily wall adjacent the periphery of the perforation. The ends of the suture are tensioned to reduce the distance between the visceral anchors and compress the bodily wall around the perforation. The ends of the suture are secured to maintain the compression of the bodily wall and close the perforation.

摘要： A device for directing a wire guide into a bodily passageway such as a branch of the biliary tree or other difficult to access bodily passageway. The device includes a member, such as an inflatable balloon or a self-expanding basket, for obstructing a first passage. Once the balloon is inflated, or the basket expanded, the wire guide can be reliably directed or deflected into a preferred adjacent passageway in order to cannulate the preferred adjacent passageway. A procedure for cannulating a preferred passageway by obstructing a passageway in the natural flow-path of a wire guide is also provided.

摘要： The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.

摘要： Medical system and methods are provided for forming an Anastomosis, such as an intestinal bypass anastomosis for treatment of obesity or diabetes. The medical devices and methods are minimally invasive and reduce complications. One embodiment of the method includes forming a first opening in the first section and forming a second opening in the first section. A proximal portion of the second section is moved to a position adjacent the first opening, and a distal portion of the second section is moved to a position adjacent the second opening. In this manner, an intermediate portion of the second section extends along the first section and an anastomosis can then be formed between the first section and the second section.

摘要： A stapler for delivering a staple formed from a shape memory material is disclosed. The staple includes a first tine and a second tine connected by a bridge. The staple may be disposed within the stapler in an open position with the first tine distal of the second tine. The stapler is configured to sequentially deliver the first tine and the second tine, respectively, to opposing body tissues. The stapler includes an elongate shaft (e.g., a catheter) having a working lumen and a control mechanism for delivering the staple. A drive cable extends along the working lumen of the elongate shaft. Upon warming up to a temperature at or above a transformation temperature of the shape memory material, the staple may assume a closed position, thus drawing together opposing body tissues and closing an incision.

摘要： The present embodiments provide a removable medical device, comprising a sleeve having proximal and distal ends and a lumen extending therebetween. At least one support member having an expanded deployed configuration is coupled to the sleeve using at least one permanent connector. A patch member comprising a resorbable material is coupled to at least a portion of an outer surface of the sleeve using at least one temporary connector. In use, when the support member is in the expanded deployed configuration, at least a portion of the patch member contacts the target site and fluid flows through the lumen of the sleeve. In a separate procedure, a retrieval member is operable to facilitate removal of the sleeve and support member while leaving the patch member disposed within the bodily passageway.
