Patent number: 9642734Abstract: An implant includes a collapsible anchor to be deployed within a lumen and a protrusion coupled to the anchor. The protrusion, in a constrained state, extends a distance from an exterior surface of the anchor and, in an unconstrained state, extends further from the exterior surface of the anchor. Also included is a biodegradable constraint, such as a biodegradable tube or suture, configured to maintain the protrusion in the constrained state until the constraint releases. The implant may include additional biodegradable constraints, each constraint configured to maintain the protrusion in a different constrained state and to degrade over a different predetermined period after the implant has been deployed within the lumen. The protrusion may include a bi-directional barb or an open loop. The protrusion may be configured to penetrate a wall of the lumen and to allow tissue to grow about the protrusion.Type: GrantFiled: August 14, 2014Date of Patent: May 9, 2017Assignee: GI Dynamics, Inc.Inventors: David A.

Publication number: 20160113800Abstract: An endoscope hood device for moving a gastrointestinal implant device within a natural lumen of a gastrointestinal tract. The endoscope hood device comprises an atraumatic flared retrieval hood configured to attach to and fit over a distal end of an endoscope. The atraumatic flared retrieval hood comprises a length configured to cover a plurality of protrusions on a surface of the gastrointestinal implant device, the plurality of protrusions comprising both proximal facing protrusions and distal facing protrusions of the gastrointestinal implant device. The atraumatic flared retrieval hood comprises a diameter configured to fit within a human esophagus without damage to the esophagus, and comprises a material of a bend radius configured to move slidably against the esophagus without damage to the esophagus.Type: ApplicationFiled: October 21, 2015Publication date: April 28, 2016Inventors: Andres Chamorro, III, David A.

Patent number: 9265596Abstract: An implant (100) includes a protrusion (110) with an open or rounded loop (112) (or open head) connected to a collapsible anchor. The protrusion may include a straight length of wire (114) or a helical length wire, with one or more wire loops (112) at the end of the length forming the loop. Upon deployment within the gastrointestinal tract, the protrusion expands from a collapsed state, alongside the anchor, to a relaxed state, in which the protrusion extends outward from the anchor. As the protrusion expands to its relaxed state, it pushes the loop into the wall of the duodenum, causing the loop to penetrate the duodenal wall. A pocket of scar tissue forms about the head and possibly through an opening in the head, securing the anchor within the duodenum. The implant may also include a thin-walled sleeve that is coupled to the anchor and extended from the anchor into the intestine.Type: GrantFiled: September 10, 2010Date of Patent: February 23, 2016Assignee: GI Dynamics, Inc.Inventors: Peter Shank, David A.

Publication number: 20140296770Abstract: Gastrointestinal implants can be used to secure thin-walled sleeves, restrictor plates, and other devices within the gastrointestinal tract. An example implant includes three elements: a stomach anchor to resist distally oriented forces; a duodenal anchor to resist proximally oriented forces; and a connector element to keep the stomach anchor fixed relative to the stomach anchor. The implant is inserted into the gastrointestinal tract with a delivery device that holds the implant in a compressed state for minimally invasive delivery until the implant is positioned properly. Upon releasing from the delivery device, the implant expands to a relaxed state across the pylorus, allowing prongs that extending outward from the stomach and duodenal anchors to engage tissue in the gastrointestinal tract. The deployed implant may also include a thin-walled sleeve that extends into the intestine from the stomach anchor, duodenal anchor, or connector element.Type: ApplicationFiled: May 13, 2014Publication date: October 2, 2014Applicant: Gl Dynamics, Inc.Inventors: Sean K.
