Patent number: 7678068Abstract: Methods and apparatus for delivering an implant device within the digestive system of an animal are presented. An delivery device includes an outer sheath, or container, for storing a proximal portion of the implant device. The outer sheath is moveable relative to the stored portion of the implant device to release the proximal portion from within the outer sheath. The delivery device also includes an inner sheath defining a lumen therein that extends distal to the outer sheath, a moveable element adapted to secure the distal end of the implant to the inner sheath, and a release mechanism coupled to the moveable element for releasing the distal end of the implant. The device also includes a atraumatic tip, or ball, coupled at its distal end to facilitate guiding the delivery device through the gastrointestinal tract.Type: GrantFiled: December 13, 2005Date of Patent: March 16, 2010Assignee: GI Dynamics, Inc.Inventors: Andy H.

Patent number: 7608114Abstract: Method and apparatus for limiting absorption of food products in specific parts of the digestive system is presented. A gastrointestinal implant device is anchored in the stomach and extends beyond the ligament of Treitz. All food exiting the stomach is funneled through the device. The gastrointestinal device includes an anchor for anchoring the device to the stomach and a flexible sleeve. When implanted within the intestine, the sleeve can limit the absorption of nutrients, delay the mixing of chyme with digestive enzymes, altering hormonal triggers, providing negative feedback, and combinations thereof. The anchor is collapsible for endoscopic delivery and removal.Type: GrantFiled: December 13, 2005Date of Patent: October 27, 2009Assignee: GI Dynamics, Inc.Inventors: Andy H. Levine, John F.

Publication number: 20090182355Abstract: Gastrointestinal implants in areas such as the esophageal area, the stomach, and the intestinal area are used in the treatment of conditions like obesity and diabetes. An implant including an anchor with barbs having pores, can allow for longer term anchoring. The pores can promote tissue ingrowth from the surrounding tissue that the barb is penetrating, thus advantageously allowing increased stability and longer term anchoring compared to a non-porous barb.Type: ApplicationFiled: December 10, 2008Publication date: July 16, 2009Inventors: Andy H. Levine, David A. Melanson, Ezra S. Fishman, Ronald B. Lamport, James Loper, John Panek, Sean K. Holmes

The device further includes a collapsible anchor coupled to the proximal portion of the sleeve. The device further includes a drawstring that is threaded through a proximal end of the anchor, and barbs that extend from the exterior surface of the anchor. The collapsible anchor can be a wave anchor. The drawstring can be used to collapse at least a proximal portion of the implant device. This is useful in removing or repositioning the implant device.Type: ApplicationFiled: December 20, 2007Publication date: September 25, 2008Applicant: GI Dynamics, Inc.Inventors: John C.

Publication number: 20080208357Abstract: Method for treating a Roux-en-Y patient having fistulas and leaks as a result of bariatric surgery. A gastrointestinal implant device is anchored in the esophagus and extends through a stomach pouch into an intestine anastomosed to the stomach pouch to prevent fistulas and other damaged tissue from making contact with food and fluids entering the esophagus. The gastrointestinal implant device includes an unsupported flexible sleeve and an anchor coupled to a proximal portion of the sleeve. The flexible sleeve is open at both ends, and adapted to extend below a jejunum. The anchor is adapted to be retained within the esophagus, preferably just above the gastroesophageal (GE) Junction. The anchor can include a stent such as a wave anchor and is collapsible for catheter-based delivery and removal.Type: ApplicationFiled: February 21, 2008Publication date: August 28, 2008Applicant: GI Dynamics, Inc.Inventors: David A.

Publication number: 20080106000Abstract: An apparatus and related techniques for making a golf ball with deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides deep dimples that extend through the cover layer and/or into a layer or component underneath are disclosed. At least one percent (1%), preferably about five percent (5%), of the dimples of the ball comprise deep dimples. The cover may be a single layer or include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to or into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.Type: ApplicationFiled: October 31, 2007Publication date: May 8, 2008Applicant: CALLAWAY GOLF COMPANYInventors: MICHAEL TZIVANIS, DAVID MELANSON, VINCENT SIMONDS, KEVIN SHANNON, THOMAS KENNEDY

Publication number: 20080071383Abstract: A patient is provided with an increased sense of satiety by increasing resistance to the outflow of food from the stomach and through the intestines. Stomach emptying may be slowed with devices implantable within the gastrointestinal tract below the stomach. Implants are preferably removable and can include artificial strictures or apertures that may be adjustable or elastic to vary the rate of stomach emptying. Slowing gastric emptying may induce satiety for a longer period and may therefore reduce food consumption. Many of the embodiments include intestinal sleeves or sleeves, but they need not. The resistor concept may be applied to a simple anchor and resistor without a long sleeve.Type: ApplicationFiled: July 12, 2007Publication date: March 20, 2008Inventors: Andy Levine, Ronald Lamport, David Melanson, Stuart Randle, Ezra Fishman
