The soft tissue anchor includes a base with multiple legs extending from the base. The one or more flexible members are coupled to the base and configured to extend from the base to the bone anchor with a fixed length. With this arrangement, the fixed length of the one or more flexible members is configured to maintain a substantially fixed pre-determined distance between the soft tissue anchor and the bone anchor such that, as the bone anchor is seated into bone, the one or more flexible members pulls the soft tissue anchor down against the soft tissue to fixate the soft tissue to the bone.Type: ApplicationFiled: February 19, 2019Publication date: August 15, 2019Inventors: Erik N.

Publication number: 20190247039Abstract: Tissue repair systems which use knotless all-suture anchors and have the ability to lock multiple repair sutures within the anchor construct. The anchor construct includes a tension suture wrapped or looped upon itself to create an open eyelet, through which multiple repair sutures originating in soft tissue are passed. The location of the eyelet may be anywhere inside the all-suture anchor or adjacent to the exterior of the anchor body. Tensioning of the tension suture causes the eyelet to restrict movement of the repair sutures and secures them within or against the anchor body.Type: ApplicationFiled: November 3, 2017Publication date: August 15, 2019Applicant: Smith & Nephew, Inc.Inventors: David GREGOIRE, Vincent TANGHERLINI, Ian LO, Christopher RODRIGUEZ, Tri NGUYEN

Publication number: 20190247041Abstract: An incisionless fully endoscopic method of reducing the capacity of the stomach is provided to surgically treat obesity. The method is directed to endoluminal tissue approximation of a portion of the stomach, including at least a portion of the greater curvature thereof. The method includes a pattern of stitching in which a portion of the stomach is closed off. One stitching pattern causes the lateral portion of the stomach to be drawn to reduce the usable volume of the stomach while maintaining a pathway from the esophagus to the pylorus. As the stitching pattern advances, the fundus is automatically drawn downward so that it may be endoscopically approached for stitching in a facilitated manner. According to another aspect of the invention, another stitching pattern extends from the antrum to the fundus between the anterior and posterior portions of the stomach.Type: ApplicationFiled: April 29, 2019Publication date: August 15, 2019Applicant: Apollo Endosurgery US, Inc.Inventors: Alonso Alvarado, Manoel Galvao, Eddie Gomez, Nicole Pena, Sohail Shaikh, Chris Thompson, Erik Wilson, Natan Zundel, Robert Lulo, Ted Stephens

Publication number: 20190247042Abstract: A suture clip includes a disc body having at least two adjacent portions joined by a hinge at one end and a latch at another end. Suture engagement surfaces are formed on a first and second portion of the disc body so that the first and second suture engagement surfaces can close sufficiently tightly to immobilize a pair of suture lengths therebetween when the two portions are closed and held together by the latch. A suture clip applier holds a plurality of such suture clips typically in a magazine, an open configuration where the suture engagement surfaces are held apart. Single suture clips are advanced by an advancement mechanism over a pair of suture ends having a midsection in tissue. A closing mechanism closes and latches the first and second portions of the disc body together to capture the pair of suture ends therebetween.Type: ApplicationFiled: January 7, 2019Publication date: August 15, 2019Applicant: Vquad Medical LLCInventors: Sebastian Khairkhahan, Alexander Khairkhahan

Publication number: 20190247043Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.Type: ApplicationFiled: April 25, 2019Publication date: August 15, 2019Applicant: Muffin IncorporatedInventors: Shaun Davis Gittard, John C.
