  • Patent number: 7837645
    Abstract: An endoscopic device separates ingested food from gastric fluids or gastric fluids and digestive enzymes, to treat obesity. In a particular embodiment a gastric bypass stent comprises a tubular member and two or more stent members defining a lumen. The tubular member has a substantially liquid impervious coating or covering and one or more lateral openings to permit one-way liquid flow.

  • Publication number: 20080228126
    Abstract: Methods for inhibiting disruption of the healing process in a hollow body organ such as a stomach that is physically modified to restrict or reduce its food receiving capability are described. A physical boundary is used to form the stomach modification. An inlet portion of the modified stomach communicates with the esophagus and an outlet portion of the modified stomach communicates with the small intestine. A bypass shunt is inserted into the modified stomach alongside the physical boundary. The shunt enables food to pass from the esophagus through the shunt to the small intestine thereby reducing food and fluid contact with the physical boundary, and reducing pressure and tension forces at the physical boundary that establishes the stomach pouch. The shunt is inserted during the stomach modification procedure.

  • Patent number: 5855601
    Abstract: An artificial heart valve comprises a relatively rigid stent member having a first cylindrical shape and a flexible valve disposed in the stent member, the stent member being self-expandable to a second cylindrical shape and collapsible to its first cylindrical shape. The valve comprises a circular portion comprising a plurality of leaflets extending from the periphery of the circular portion towards the center thereof, the leaflets being configured to allow for flow of blood through the valve in one direction only. The diameter of the circular portion is substantially the same as the inside diameter of the stent member when the stent member is in its second cylindrical shape, the valve member being attached to the stent member.

  • Patent number: 5549621
    Abstract: The present invention pertains to an apparatus and method which enable the performance of vertical banded gastroplasty (VBG) without the use of staples. Further, a laparoscopic instrument which can be used in combination with the VBG apparatus and method is also disclosed.The laparoscopic instrument can also be used in combination with surgically functional elements other than the VBG apparatus. A particular advantage of the laparoscopic instrument is that surgically functional elements attached at the leading edge of levered jaws of the instrument can be rotated at least 180 degrees in a plane which is substantially parallel to a plane passing horizontally through the longitudinal centerline of the levered jaws.

  • Patent number: 5411508
    Abstract: An intestinal steerable endoscopic stapler for stapling tubular tissue is provided comprising a circular anvil member having a circular anvil stapling surface and a cutting block surface radially inwardly of the stapling surface. A head assembly has a circular staple driver for driving staples in an array corresponding to the anvil surface and a circular cutting blade corresponding to the cutting block. A flexible tube has a distal end at the head assembly and a handpiece end. A scope in the form of an eyepiece in the handpiece optically connected to a lens in the head assembly is provided for viewing a region of space beyond the head assembly. A steering arrangement is provided for pivoting the head assembly relative the flexible tube to thereby steer the head assembly in a body cavity.
