  • 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.

  • Patent number: 11160548
    Abstract: Instruments for placing complex sutures into animal tissues, including instruments useful in arthroscopic surgical techniques which minimize incision size. Manipulate the flat tissue by, for example, rolling, wrinkling, folding, bending or tucking the tissue so that a needle can be placed through the tissue more than once. Sutures are placed, for example from top-to-bottom and bottom-to-top with a single pass of a straight needle. Roll, wrinkle, fold, bend or tuck the flat tissue so that a needle can be placed through the tissue more than once. Suturing a loop through the tissue that another suture will pass through result in sewing both sides of the tissue. This will allow surgeons to place complex locking and grasping suture configurations that will significantly improve the repair.
