  • Patent number: 10912549
    Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.

  • Patent number: 10898178
    Abstract: Devices and methods for soft tissue reconstruction are provided. One exemplary embodiment of a device includes a body a suture filament extending through through-holes formed in the body. The suture is formed into an overhand knot having three collapsible openings with filament limbs extending from the knot. The limbs can be passed through the thru-holes of the body and selectively into the collapsible openings of the overhand knot to form coils extending to an opposite side of the body. For example, one limb can be passed through first and second collapsible openings to form two coils, while the other limb can be passed through the first and third collapsible openings to form two coils. The collapsible openings are collapsed around the limbs disposed in the openings, resulting in a secured overhand knot. Other configurations of knots, as well as devices and methods for use in tissue reconstruction, are also provided.

  • Publication number: 20210007840
    Abstract: Systems and methods for preparing a tissue repair construct for a ligament reconstruction procedure using a reinforced whip-stitching are provided. The described techniques include passing a needle having suture tails attached thereto through a first surface of a graft at an origin point so that a portion of the suture tails exits on a second, opposite surface of the graft while a terminal length of the suture tails is maintained on the first surface of the graft. Multiple suture loops are formed by repeatedly passing the needle with the suture tails around opposite sides of the graft and through the first surface of the graft at subsequent entry points spaced apart along a length of the graft. Each loop is formed so that the construct is reinforced by having a terminal length of each of the suture tails disposed between the first surface of the graft and the loop.

  • Patent number: 10856967
    Abstract: A device having one or more adjustable loops or coils associated with an implant body for use in soft tissue reconstructions is provided. One exemplary embodiment of a device includes a body and a suture filament, with the filament being used to form a self-locking sliding knot disposed on a top side of the body and a plurality of adjustable coils that are substantially disposed on the body's bottom side. Terminal ends of the filament located above the body's top side can be passed through an opening of a Lark's Head knot from opposite sides, thus forming a self-locking sliding knot, and then the terminal ends can be tensioned to adjust a circumference of the coils. Changing a coil's circumference changes a location of a ligament graft disposed on the coil. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.

  • Publication number: 20200178951
    Abstract: A suture anchor for fixation within an anatomical structure includes an actuation member in contact with an anchor body at a first location thereof. The anchor body is elongate along a direction of elongation and defines a central axis. In a neutral configuration, the anchor body is flat and defines a thickness along a transverse direction and a width along a lateral direction, the width being greater than the thickness. The anchor body has first and second tails that are braided together along a portion of the actuation member from the first location to a second location of the anchor body. The actuation member is configured to apply a force to the braided anchor body so as to actuate the anchor body in a manner increasing its maximum thickness along a second direction that is angularly offset from the direction of elongation.

  • Patent number: 10667901
    Abstract: A graft retention device has an elongated body with a first and second ends and a midpoint therebetween. A pair of elongated slots formed through the body defines a tang therebetween. A graft retention loop is disposed over the tang and is slidable therealong. A trailing line connects to the body adjacent the slots and extends therefrom through the graft retention loop toward the first end. Tension applied to the trailing line thus tends to urge the graft retention loop away from the first end and toward the midpoint.
