  • Publication number: 20240090893
    Abstract: A surgical construct provides a dual purpose of a suture retainer and a finger protector. The surgical construct efficiently allows for surgeon's protection when using tensionable fixation devices (such as tensionable anchors) without extra steps or added cost. The surgical construct can retain suture and can be also worn on fingers to prevent glove and/or finger cuts when tensioning sutures.

  • Publication number: 20240081805
    Abstract: A suture anchor for knotless fixation of tissue. The suture anchor includes an implant configured to hold a suture to be anchored in bone without requiring suture knots. The suture is secured in bone by inserting the implant holding the suture into a hole in the bone, and advancing a fixation device, such as a cannulated interference screw, over a shaft at the proximal end of the implant.

  • Publication number: 20240081809
    Abstract: Surgical constructs, assemblies, kits and methods of tissue fixation are disclosed. A suture passing instrument includes a curved tip integral with a distal end of a shaft, a hand assembly mounted on a proximal end of the shaft, and a flexible strand attached to one or two needles and loaded through a cannulation of the shaft. The curve-shaped tip is adapted to engage dural tissue during repairs of the dura mater. The suture passing instrument can grasp and manipulate dura mater and can allow multiple suture passes through the dura mater without removal of the instrument from the durotomy site. The suture passing instrument is provided with a safety mechanism that prohibits the needle(s) to be fired into nerves, providing a safe, reliable, inexpensive, and speedy repair of a durotomy.

  • Patent number: 11844511
    Abstract: This disclosure details a surgical system and method, which is permits percutaneous insertion of anchors, and is useful in orthopedic surgical procedures involving fixation of soft tissue to bone. Because the anchors may be inserted percutaneously, the anchors can be inserted into bone without requiring a skin incision and without requiring a pre-drilled bone hole. As such, use of the disclosed system and method leads to a reduction in the number of steps in a surgical procedure, which reduces surgery time, while also reducing the size of openings formed in the skin relative to other known techniques, which reduces recovery times and results in smaller and less noticeable scarring.

  • Publication number: 20230363753
    Abstract: Soft anchor constructs and methods for soft tissue to bone repairs. The soft anchors may be knotted or knotless constructs. The soft anchors include a body formed of various soft materials (including, but not limited to, suture) and provided in various shapes and configurations that confer the anchors the ability to be easily inserted within bone tunnels or sockets and be bunched up within the bone tunnels or sockets. At least one closed loop or soft eyelet is attached to the soft anchor to allow additional sliding strands and/or shuttle/pull devices (suture passing devices) to pass through the eyelet and aid in the knotted or knotless fixation of tissue to bone.

  • Publication number: 20230255612
    Abstract: Tensionable, knotless, self-locking surgical constructs and methods for surgical repairs are disclosed. A tensionable, knotless, self-locking surgical construct includes a flexible coupler (repair suture) and a plurality of shuttle/pull devices loaded onto a fixation device. The fixation device can be a knotless fixation device such as a knotless soft anchor, for example, an all-suture knotless anchor. The knotless surgical construct provides multiple passes of the flexible coupler itself (repair suture itself), to achieve the desired friction and to also create a reverse purchase resistance to loosening. The flexible coupler (repair suture) is passed around tissue two or more times (and subsequently through the cannulation of the anchor sheath two or more times) creating a stuffed friction effect. There is no cinching loop in the final repair.

  • Patent number: 11690610
    Abstract: Suture constructs and methods for soft tissue to bone repairs. The suture construct is a soft, suture-based anchor which is self-cinching and has a specific, accordian-type configuration (i.e., with the ability to fold from a first, extended position to a second, folded or compressed position). The suture-based anchor may be formed essentially of a flexible material such as a high strength surgical suture, suture chain, or suture.

  • Publication number: 20230113040
    Abstract: This disclosure details a surgical system and method for changing one or more dimensions of harvested tissue, such an autograft, which is harvested from one location in a patient's body and used for a surgical repair or reconstruction procedure in another location in the patient's body. An example surgical system includes a first press component defining a cavity configured to receive harvested tissue, and a second press component including a projection insertable into the cavity. Further, at least one of the first and second press components are made of a transparent or semi-transparent material such that when harvested tissue is in the cavity and when the projection is inserted into the cavity, the harvested tissue is visible through at least one of the first and second press components.

  • Patent number: 11571200
    Abstract: A swivel suture anchor for knotless fixation of tissue. The suture anchor includes an anchor tip configured to capture suture, the anchor tip being rotatably received within a fixation device upon advancement of the fixation device over a shaft of the anchor tip. The anchor tip is configured to receive a suture to be anchor in bone without requiring suture knots. The anchor tip can be a conical metal tip which is self-punching and avoids the need for pre-drilling a hole in bone. The anchor tip includes a closed aperture to allow free sliding of a suture strand. The suture is secured in a hole in bone by inserting the anchor tip into bone, and advancing a fenestrated fixation device, such as a cannulated interference screw, over a shaft of the anchor tip.
