  • Patent number: 11096682
    Abstract: A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop.

  • Publication number: 20210052268
    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.

  • Publication number: 20200345343
    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.
