  • Publication number: 20220142636
    Abstract: An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

  • Patent number: 10765420
    Abstract: The present disclosure concerns a surgical instrument for manipulating suture. In particular, the present disclosure relates to an instrument for passing suture through tissue. There is described a surgical instrument having a shaft and a handle connected to the proximal end of the shaft. The shaft is formed from a tubular member having a proximal end and a distal end, with a lumen extending between the proximal and distal ends, and a tip distal to the tubular member. The shaft also includes a distal portion having an opening in a sidewall, proximal to the tip. The opening is in communication with the lumen through a side channel. The instrument further includes a suture snare, the snare being slidably receivable within the lumen and side channel, and movable between extended and retracted positions for capturing suture.

  • Publication number: 20200155143
    Abstract: The present disclosure relates to a suture anchor. The suture anchor includes a body having a proximal end and a distal end, the body including threads along at least a partial length of the body and at least one through hole, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape. Delivery devices and anchor dilators are also disclosed.

  • Patent number: 10603028
    Abstract: Finger traps for collapsible suture loops are provided. In general, a suture coupled to an implant can be tensioned to facilitate desirable positioning of the implant relative to tissue in a patient's body. The suture can include a finger trap and a knot. In general, the finger trap is a hollow area of the suture through which the suture passes through itself and is configured to slide in a single direction when under tension. In an exemplary embodiment, the knot is located along a length of the suture that is closer than the finger trap to a tail of the suture that is being pulled to tension the suture.

  • Patent number: 10582920
    Abstract: Examples of a suture anchor (100) having a non-expandable body (105) and expendable cap (110) are described herein. In response to an axial insertion force that brings the non-expandable body and expendable cap together inside a bone hole, the expendable cap expands radially. This creates a radial force of expansion that advantageously augments an interference fit between the suture anchor and bone hole, which leads to higher fixation strength. Other examples include retention features that inhibit the expendable cap from returning back into its unexpanded state. This advantageously maintains the radial force of expansion against the surrounding pressure of the walls of the bone hole pressing back on the suture.

  • Patent number: 10582922
    Abstract: A one-piece knotless suture anchor with a breakaway distal tip is disclosed. The suture anchor includes a thin section connecting a distal anchor portion and proximal anchor portion. The thin section has a cutaway geometry allowing it to break in a repeatable manner. Force from a driver breaks the thin section connecting the distal and proximal anchor portions. The proximal anchor portion slides distally over the elongated member (either distal or proximal to the distal eyelet) and a repair suture is pinched between the distal and proximal anchor portions, or in between the bone tunnel walls and outer diameter of the sleeve, thereby fixing the repair suture in place without tying an arthroscopic knot.
