  • Patent number: 11389154
    Abstract: A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a continuous array of single anchor to anchor stitches which can be placed close together in high density to form a line or region of stitches for a more robust securement of soft tissue to bone.

  • Patent number: 11393535
    Abstract: Embodiments for ultra-precise tuning of a selected memory cell are disclosed. The selected memory cell optionally is first programmed using coarse programming and fine programming methods. The selected memory cell then undergoes ultra-precise programming through the programming of an adjacent memory cell. As the adjacent memory cell is programmed, capacitive coupling between the floating gate of the adjacent memory cell and the floating gate of the selected memory cell will cause the voltage of the floating gate of the selected memory cell to increase, but in smaller increments than could be achieved by programming the selected memory cell directly. In this manner, the selected memory cell can be programmed with ultra-precise gradations.

  • Patent number: 11382613
    Abstract: A method and apparatus are provided for transtendinous implantation of a toggle-type bone anchor. Measured from the top surface of the tendon, the entire bone anchor is inserted to a depth of greater than or equal to 20 mm. during a rotator cuff repair on the humeral head. The anchor is pushed by the same bone punch that formed the initial hole to assure proper depth of placement. Further, the apparatus includes a nub portion that, in use, protrudes into the bone hole formed by the bone punch and maintains registration with the bone hole when the bone punch is retracted. An angled distal end on the anchor initiates toggling during insertion into the bone and at least one proximal projecting fin prevents the anchor from backing out of the bone hole while facilitating further rotation of the anchor when a suture is pulled to complete toggling.

  • Publication number: 20220211072
    Abstract: A frozen product dispenser provides a controller to control the rate of freezing and the temperature range of a frozen product. The controller monitors the temperature of the product as well as the torque applied to a scrapper blade. For example, the torque may be measured based on monitoring a current draw of a scrapper motor. The torque may be tracked over time to determine a rate of change in the torque. The rate of freezing may be controlled by setting a maximum rate of increase in the torque. Upon determining that the rate of increase in the monitored torque exceeds the maximum rate, a compressor for the frozen product dispenser may be turned off for a predetermined period of time and/or a hot gas bypass may be opened. A heat transfer medium may decouple thermal contact between an evaporator and the product to control the rate of freezing.
