Patent number: 7763040Abstract: A tissue connector assembly comprising a clip movable between an open configuration and a closed configuration and a mechanical restraining device attached to the clip for restraining the clip in its open configuration. A needle may be releasably attached to the clip. A method for connecting tissues is also disclosed. The method includes inserting a clip through tissue with the clip being biased in an open position by a restraining device secured to the clip, and removing the restraining device from the clip.Type: GrantFiled: February 10, 2003Date of Patent: July 27, 2010Assignee: Medtronic, Inc.Inventors: Laurent Schaller, Charles T.

Publication number: 20030208260Abstract: This invention is a medical device and a method of using it. The device is a foldable stent or stent-graft which may be percutaneously delivered with (or on) a catheter, typically an endovascular catheter, to a body cavity or lumen and then expanded. It may also be delivered or via surgical (or other) techniques. The expandable stent structure utilizes torsional members which distribute bending and folding loads in such a way that the stent is not plastically deformed. The stent's configuration allows it to be folded or otherwise compressed to a very small diameter prior to deployment without changing the length of the stent. The graft component cooperating with the stent is tubular and preferably is blood-compatible material which may, if desired, be reinforced with fibers. The stent is able to provide collapsible support for otherwise frangible graft material.Type: ApplicationFiled: May 9, 2003Publication date: November 6, 2003Inventors: Lilip Lau, Charles T. Maroney, William M. Hartigan, Sharon Lam

Patent number: 6613072Abstract: This invention is a medical device and a method of using it. The device is a foldable stent or stent-graft which may be percutaneously delivered with (or on) a catheter, typically an endovascular catheter, to a body cavity or lumen and then expanded. The stent's configuration allows it to be folded or otherwise compressed to a very small diameter prior to deployment without changing the length of the stent. The deployment procedures may involve the use of an outer sleeve to maintain the stent or stent-graft at a reduced diameter or may involve one or more external or internal “slip-lines” or “tether wires” to hold and then to release the device. A removal slip line for holding the stent in the deployable configuration can be woven along longitudinal fold line using the sack knot.Type: GrantFiled: July 18, 1997Date of Patent: September 2, 2003Assignee: Gore Enterprise Holdings, Inc.Inventors: Lilip Lau, Charles T.

Patent number: 5919225Abstract: The present invention relates to a process for deploying a folded stent or stent-graft in a lumen. The stent or stent graft is maintained in the folded configuration by a slip line that is attached to the folded stent or stent-graft, along a longitudinal fold edge. The folded stent or stent-graft is inserted into a lumen and the slip line is axially moved along a longitudinal line to allow the folded stent or stent-graft to expand to its enlarged, deployed configuration.Type: GrantFiled: July 14, 1997Date of Patent: July 6, 1999Assignee: Gore Enterprise Holdings, Inc.Inventors: Lilip Lau, Charles T.

The graft component cooperating with the stent is tubular and preferably is blood-compatible material which may, if desired, be reinforced with fibers. The stent is able to provide collapsible support for otherwise frangible graft material. When used with super-elastic alloys, the stent may be collapsed at a convenient temperature either above or, preferably, below the transition temperature of the alloy.Type: GrantFiled: July 21, 1997Date of Patent: February 23, 1999Assignee: Gore Enterprise Holdings, Inc.Inventors: Lilip Lau, Charles T.
