  • Patent number: 11871971
    Abstract: A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one of the outer housing or the inner shaft to the first portion of the tibia; coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first porti

  • Patent number: 11583269
    Abstract: A suture passing device includes a jaw assembly that is moved to an open configuration after exiting a hollow needle distal tip and moved to a closed configuration when retracted into the needle tip. The jaw assembly may include a pair of jaw members biased to a default diverging configuration. A suture capturing mechanism formed on the jaw members securely captures suture to both push and pull the captured when the jaw assembly is retracted into the hollow distal tip. The jaw members have configurations of teeth that may be staggered axially and vertically.

  • Publication number: 20220265267
    Abstract: A suture passer includes a first shaft comprising a hollow tube and a distal portion located distally of a distal end of the hollow tube; a needle comprising a needle tip and a needle shaft translatably mounted in the hollow tube for passing a suture loaded holder through tissue positioned between the distal end of the hollow tube and the distal portion of the first shaft; an actuatable engagement located in the distal portion of the first shaft for retaining the suture loaded holder after the suture loaded holder has passed through the tissue; a sheath extending around an exterior of the needle shaft and translatable with the needle shaft for at least a portion of a stroke of the needle, wherein the sheath is moveable relative to the needle for actuating the engagement to an unlatched position to release the holder from the distal portion of the first shaft.

  • Publication number: 20220192657
    Abstract: A method for passing a suture through tissue includes positioning a suture passer in a surgical cavity, the suture passer comprising a tube defined by a wall and a suture retainer received in the tube and configured to extend at least partially out of the tube; retaining a suture between a retaining surface of a cutaway in the tube and a proximally facing portion of a distal portion of the suture retainer such that the suture is retained against the retaining surface of the cutaway by the proximally facing portion of the distal portion of the suture retainer, wherein a distal end of the suture retainer is distal to the retaining surface of the cutaway and proximal to the distal end of the tube when the suture is retained against the retaining surface of the cutaway; and passing the suture passer with the retained suture through the tissue.

  • Publication number: 20220183675
    Abstract: A method for passing a suture through tissue includes extending a distal end of a suture retainer of a suture passer from a distal portion of a tube of the suture passer; locating a suture adjacent the suture retainer; retracting the suture retainer partially into the tube and retaining a suture between a retaining portion of the suture retainer and a first portion of a cutaway in a side of a wall defining the tube, wherein the first portion of the cutaway curves around a longitudinal axis of the distal portion of the tube and two longitudinally extending portions of the cutaway extend distally from the first portion to a distal end of the tube; and passing the distal portion of the suture passer with the retained suture through tissue.

  • Patent number: 11246586
    Abstract: A surgical instrument can manipulate and pass suture through tissue. The device can easily pass suture through tissue with the suture fixed to the mechanism or where the suture is captured by the mechanism and allowed to slide. Along with this ability to control suture in one of two ways is a feature to provide a large amount of suture on the other side of the tissue that will be relatively easy for the surgeon to grab and pull out of the arthroscopic portal. The device includes a handle with a hollow shaft extending therefrom and a set of fingers movable into and out of the shaft. The fingers can be designed to capture suture, permit the suture to slide while captured, and optionally hold the suture in the device.
