Publication number: 20220183676Abstract: A locking device or button configured for use with a tensionable fixation member to stabilize, fix, repair bone or soft tissue is described herein. By way of example, the locking device of the present disclosure allows for optimal tensioning of the repair or construct. The locking device of the present disclosure provides repair security and prevents loosening of the repair construct by allowing passage and tensioning of the tensionable fixation member when the tensionable fixation member is pulled through the locking device in a first direction (e.g., the “tensioning direction”), and preventing passage and loosening of the tensionable fixation member (e.g. locking the tensioning member) when the tensionable fixation member is pulled in a second direction (e.g., the “opposite direction” or “loosening direction”), without the need for a secondary locking element.Type: ApplicationFiled: December 14, 2021Publication date: June 16, 2022Applicant: Dunamis Medical Technologies, LLCInventors: Forrest Samuel, Prithviraj Chavan

Patent number: 11350968Abstract: A modular polyaxial bone screw includes a poly-axial bone screw, a polyaxial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a resilient, tapered base with a plurality of slots in and about its end that allow the end to splay outwardly over and upon the head of the bone screw to create a snap or frictional interference fit between the splayed collet and the bone screw head when a spine rod is fixed in the tulip head.Type: GrantFiled: February 13, 2020Date of Patent: June 7, 2022Assignee: LIFE SPINE, INC.Inventors: Forrest Samuel, Gregory Palagi

Publication number: 20220167962Abstract: A system and method comprising an anchor assembly including an anchor and a locking element, a tensionable fixation member (e.g., surgical suture, tape, etc.), and a release member, wherein the anchor further comprises a first end, second end and anchor body. This re-tensionable anchor is designed to be implanted into bone. One end of a suture or other tensionable fixation member is attached to the tissue on one end to assist with fixation of soft tissue. Once the anchor has been seated in the bone, the second end of the suture or tensionable fixation member is pulled through a “one-way only” passage in body of the anchor. When the tensionable fixation member enters the body of the anchor, it traverses past by bending or deflecting out of the way a locking element within the anchor that will permit passage of the suture and will stay in contact with the fixation member via elastic compression that results from the elastic bending or deflection but prevent it from passing back.Type: ApplicationFiled: December 1, 2021Publication date: June 2, 2022Applicant: Dunamis Medical Technologies, LLCInventors: Forrest Samuel, Prithviraj Chavan
