Abstract: Devices and methods for treating aneurysms, such as abdominal aortic aneurysms (“AAA”) generally include one or more stent-graft devices. Some embodiments include self-expanding and/or balloon-expandable stent components and one or more graft components coupled with the stent components. Using various combinations of self-expanding stent members, balloon-expandable stent members, graft members, and/or anchoring members enhances the anchoring abilities of a stent-graft device to prevent leakage around it, and may further allow the device to be adjusted after placement at a site for treatment. Some embodiments further include a skirt graft member for further prevention of leakage and/or device slippage.

Abstract: Various obesity treatment tools and methods are described herein, as well as treatments for other gastric-related diseases, e.g., GERD. Treatment includes reducing the size of the stomach pouch to limit the caloric intake as well as to provide an earlier feeling of satiety. This may be done by creating a smaller gastric pouch within the stomach directly from the interior of the stomach itself. The smaller pouches may be made through the use of individual anchoring devices, rotating probes, or volume reduction devices. A pyloroplasty procedure may also be performed to render the pyloric sphincter incompetent. A gastric bypass procedure may additionally be performed using atraumatic magnetic anastomoses devices so that sugars and fats are passed directly to the bowel while bypassing the stomach. Many of these procedures may be done in a variety of combinations.
