Publication number: 20200030129Abstract: A surgical method includes forming a first tissue fold, piercing the first tissue fold with a needle, deploying a first tissue anchor from the needle, withdrawing the needle from the first tissue fold, deploying a second tissue anchor from the needle, with the first tissue anchor connected to the second tissue anchor to form a first tissue anchor pair, and attaching a gastrointestinal implant to the tissue anchor pair. The gastrointestinal implant may have a tether including a tether loop, with the gastrointestinal implant attached to the tissue anchor pair by positioning the tether loop between the tissue fold and first or second tissue anchor. The gastrointestinal implant may be a gastric sleeve or a device holding microbiota.Type: ApplicationFiled: July 25, 2018Publication date: January 30, 2020Inventors: Christopher James Earley, Tracy D.

Patent number: 10433850Abstract: A ligature delivery device includes a control member, an elongated shaft, and an end effector attached to the distal end of the elongated shaft. An activation mechanism provides an user-operable connection between the control member and the end effector. In several embodiments, the end effector includes a reverse grasping mechanism. Several embodiments of ligature devices are adapted to be deployed endoscopically and/or translumenally using the reverse-grasping delivery device.Type: GrantFiled: August 2, 2016Date of Patent: October 8, 2019Assignee: USGI Medical, Inc.Inventors: Richard C. Ewers, Christopher James Earley, Barton P. Bandy, Eugene G. Chen, Haio Fauser

Patent number: 8920436Abstract: An endoscopic tissue anchor deployment device includes a handle, an elongated shaft defining an internal lumen, and an end effector attached to the distal end of the elongated shaft. A tissue anchor catheter is removably inserted through the lumen of the elongated shaft, the catheter having a tissue anchor assembly that is deployable from its distal end. The handle may include a pin and track assembly that define a series of handle actuation steps corresponding to deployment steps for the deployment device end effector and the tissue anchor catheter. In some embodiments, the handle includes a catheter stop member that prevents movement of the tissue anchor catheter under certain circumstances, and a handle stop member that prevents actuation of the handle under certain circumstances.Type: GrantFiled: January 11, 2012Date of Patent: December 30, 2014Assignee: USGI Medical, Inc.Inventors: Cang Lam, Richard C. Ewers, Christopher James Earley

Publication number: 20130217957Abstract: A surgical method for treating obesity by reducing the size and/or function of the stomach includes forming at least two plications or tissue folds in tissue of a patient using anchor assemblies having a loop. The plications are then optionally allowed to heal. A loop suture or wire is threaded through the loops. The loop suture is then tensioned to draw the plications towards each other. The loop suture is then secured via a knot or a cinch. When the method is performed in the stomach for treatment of obesity, forming the plications reduces the volume of the stomach. Drawing the plications together creates a contracted tissue area which further reduces the volume of the stomach. Additional plications may also be formed and drawn together with the same loop suture, or with a different loop suture.Type: ApplicationFiled: February 6, 2013Publication date: August 22, 2013Applicant: USGI Medical, Inc.Inventors: Tracy D.

Publication number: 20100137681Abstract: Endoscopic instrument management systems are described herein which allow one or more operators to manage multiple different instruments utilized in endoscopic procedures. In one aspect, responsibility for instrumentation management between one or more operators may be configured such that a first set of instruments is controlled by a primary operator and a second set of instruments is controlled by a secondary operator. The division of instrumentation may be facilitated by the use of separated instrumentation platforms or a single platform which separates each instrument for use by the primary operator. Such platforms may be configured as trays, instrument support arms, multi-instrument channels, as well as rigidized portions of instruments to facilitate its handling, among others. In another aspect, one or more plastically deformable instrument manifolds are provided to guide flexible endoscopic instruments into and through an endoscopic access device.Type: ApplicationFiled: November 20, 2009Publication date: June 3, 2010Applicant: USGI Medical, Inc.Inventors: Richard C.
