  • Patent number: 7959665
    Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. A plurality of inverted cylindrical end rings can be coupled at least in part to a plurality of adjacent cylindrical rings in the form of mirror images such that a symmetrical configuration is present on at least one of a proximal end and a distal end of the stent. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The inverted end ring configuration of the stent aims at reducing the stent-to-shoulder distance as well as delivering therapeutic drug to the peri-stent area while maintaining a pristine stent deployment.

  • Patent number: 7909838
    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. Treatment may create enforced behavioral modifications by discouraging the ingestion of high-caloric foods.
