20090069879 | IMPLANT DELIVERY SYSTEM WITH MARKER INTERLOCK - An implant delivery system is disclosed. The delivery system includes an elongated member having an implant mounting location. A self-expandable implant is mounted at the implant mounting location. The implant is held in a compressed orientation by a retractable sheath. An interlock structure prevents the implant from deploying prematurely as the sheath is retracted. The interlock structure includes radio-opaque markers that identify the position of the implant. | 03-12-2009 |
20110009690 | External Anchoring Configurations for Modular Gastrointestinal Prostheses - Components may be used separately or in combination to create anchoring systems for intra-luminal implants for the treatment of metabolic disorders such as obesity and diabetes. Various systems include an external component adapted for deployment around a portion of the gastrointestinal tract (e.g., the duodenum) and an internal component adapted for implantation within the gastrointestinal tract. Various systems use anchoring means that are based on mechanical interference, elasticity, spring force, shape memory transformation, magnetic attraction, repulsion and/or levitation. Various embodiments rely on longitudinal anchoring of the implants with minimal force against tissue. | 01-13-2011 |
20110106273 | GASTROINTESTINAL PROSTHESES HAVING PARTIAL BYPASS CONFIGURATIONS - A system of components may be used separately or in combination to create partial bypass of food, stomach and intestinal secretions and digestive enzymes. The systems are designed to be modular so as to allow the physicians to quickly replace certain elements to tailor the amount of material bypassed, the restriction applied to food passage, and the origin and destination of bypass according to the patient's individualized clinical needs. | 05-05-2011 |
20120065571 | EXPANDABLE PYLORIC ANCHORS AND METHODS FOR SECURING INTESTINAL BYPASS SLEEVES - A gastrointestinal device for implanting within a patient's gastrointestinal tract includes first and second expandable anchoring rings configured to be disposed on either side of a patient's pylorus. The first expandable anchoring ring has a collapsed configuration and an expanded configuration, wherein in the expanded configuration the first expandable anchoring ring has a diameter larger than a maximum opening diameter of the pylorus. The second expandable anchoring ring also has a collapsed configuration and an expanded configuration, wherein in the expanded configuration the second expandable anchoring ring has a diameter larger than a maximum opening diameter of the pylorus. An intestinal bypass sleeve couples the first expandable anchoring ring and the second expandable anchoring ring, so as to allow a distance between the anchoring rings to exceed a width of the pylorus. | 03-15-2012 |
20120184893 | ANCHORS AND METHODS FOR INTESTINAL BYPASS SLEEVES - A gastrointestinal device for implanting within a pylorus, a duodenal bulb, and a duodenum of a patient's gastrointestinal tract includes an expandable structure including a proximal portion having a plurality of spring arms and a distal portion having a plurality of spring arms, the proximal and distal portions coupled by a rigid central cylinder having a diameter capable of fitting within the pylorus and having a length greater than a width of the pylorus. An intestinal bypass sleeve is coupled to at least one of the proximal and distal portions of the expandable structure and having a length sufficient to extend at least partially into the duodenum. In the expanded configuration, the proximal portion has a diameter larger than a maximum opening diameter of the pylorus and further wherein, in the expanded configuration, the distal portion has a diameter larger than a maximum opening diameter of the pylorus. | 07-19-2012 |
20120253259 | MODULAR GASTROINTESTINAL PROSTHESES - A modular system for therapy within a gastrointestinal system. The system includes anchoring or attachment functionality embodied in a low-profile implant technology and removable therapy components, which can be reversibly attached to these low-profile implants to accomplish various therapies. This modular design allows the physician to tailor the therapy to the patient's needs. The modular system has the potential to create conduits for diversion and/or restriction of food and organ secretions and to facilitate the treatment of metabolic disorders such as obesity and T2DM. | 10-04-2012 |
20120253260 | GASTROINTESTINAL PROSTHESES - A system for therapy within a gastrointestinal system includes anchoring or attachment functionality embodied in a low-profile implant technology and removable therapy components, which can be reversibly attached to these low-profile implants to accomplish various therapies. This design allows the physician to tailor the therapy to the patient's needs. The system has the potential to create conduits for diversion and/or restriction of food and organ secretions and to facilitate the treatment of metabolic disorders such as obesity and T2DM. | 10-04-2012 |
20120302936 | EXTERNAL ANCHORING CONFIGURATIONS FOR MODULAR GASTROINTESTINAL PROSTHESES - Components may be used separately or in combination to create anchoring systems for intra-luminal implants for the treatment of metabolic disorders such as obesity and diabetes. Various systems include an external component adapted for deployment around a portion of the gastrointestinal tract (e.g., the duodenum) and an internal component adapted for implantation within the gastrointestinal tract.

20130030351 | DELIVERY DEVICES AND METHODS FOR GASTROINTESTINAL IMPLANTS - Several gastrointestinal surgery procedures are effective as treatments for metabolic disorders such as obesity and diabetes. Minimally invasive procedures including intra-luminal gastrointestinal implants have been proposed to mimic the anatomical, physiological and metabolic changes achieved by these procedures. Many of these designs include long sleeve like elements that prevent contact of food with the walls of the small intestine. It is desirable to have simple delivery systems that can place these implants under endoscopic guidance. However, in order to anchor these sleeve elements safely and reliably, the inventors have previously disclosed anchoring means that anchor the sleeves at the junctions of the stomach and the intestine or the stomach and esophagus. | 01-31-2013 |
