  • Patent number: 10799370
    Abstract: A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.

  • Patent number: 10792143
    Abstract: The present invention relates to packages and methods of using packages that provide a sterile enclosure for an implant so that the implant can be transported and retrieved without being contaminated. In one embodiment, the package includes an insert with an implant disposed therein and a tray. The insert includes a first engagement feature and the tray includes a second engagement feature corresponding to the first engagement feature. The insert is sized to fit within and engage with the tray through engagement of the first and second engagement features, where in a first position the implant is secured within the package and in a second position, the implant is retrievable from the insert. The insert moves relative to the tray between the first and positions, but remains secured to it in both positions.

  • Patent number: 10709460
    Abstract: Disclosed herein are systems and methods for identifying the proper implant for use in an arthroplasty procedure and preparing a bone surface for the placement of such implant. In one embodiment, a centering guide system includes a cannulated post and a translucent surface trial where the cannulated post includes a slit defining legs that flex to engage the post when inserted in a hole of the surface trial. The system is used to confirm a suitable implant size and place a pilot wire in preparation for implant placement. The cannulated post and the translucent surface trial provide comprehensive visibility of the glenoid surface. When inserted into the surface trial, an extension of the cannulated post beyond an articulating surface of the surface trial is minimal or nonexistent. In this way, the congruence of a reamed glenoid surface can be evaluated prior to implantation of the implant.

  • Patent number: 10702397
    Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.

  • Patent number: 10702258
    Abstract: A ratcheting inserter device for tensioning a knotless suture anchor includes an outer inserter shaft and an inner inserter shaft having a common longitudinal axis. A ratcheting mechanism provided between the inner inserter shaft and the outer inserter shaft permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion at a distal end that is received by an anchor outer sleeve of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection at the distal end that is received by an inner core of the anchor for rotational movement therewith. The ratcheting inserter device rotates the inner core of the suture anchor to spool and tension suture thread. Thereafter, the ratcheting mechanism is disengaged and the inner inserter shaft is forced axially into the anchor outer sleeve.
