The introducer end wall passage joins the introducer end wall at one or more end wall edges defining an axial stop ring configured to contact the distal tip of a navigation probe between the probe shaft and a terminal end of the distal probe tip at a line of contact to thereby prevent movement of the navigation probe in the distal direction. | 2021-12-30 |
20210401458 | OBTURATOR HAVING A DISTAL ELECTRODE - An obturator includes an elongate shaft with proximal and distal portions. A button is located in the proximal portion of the elongate shaft. A cable has first and second wires and extends from the proximal portion of the elongate shaft and is attachable to a source of electrical energy. A plate is positioned in the distal portion of the elongate shaft and is coupled to the first wire. An electrode is located in the distal portion of the elongate shaft and is coupled to the second wire. An insulator is disposed in the distal portion of the elongate shaft and electrically isolates the plate from the electrode. The obturator is capable of tunneling through body tissue. | 2021-12-30 |
20210401459 | SURGICAL DEVIDE FOR IMPLANT REMOVAL - Device for removal/evacuation of an implant including a collection container with a connector for connection to a suction source and a rimmed opening sized and shaped to enter an implant pocket and to adhere to or juxtapose the implant, such that when suction is applied, the implant is sucked into the collection container. | 2021-12-30 |
20210401460 | CELL TRANSPLANTATION DEVICE AND CELL TRANSPLANTATION SYSTEM - A cell transplantation device is used to place a graft containing cells into a target region in a living body. The cell transplantation device includes a needle extending in one direction, and a filter unit made of a fibrous member. The needle has a flow channel defined therein and an opening at the tip of the needle. The filter unit is disposed at an intermediate position in the flow channel and configured to retain a graft between the filter unit and the opening when a liquid material containing the graft enters the flow channel through the opening. | 2021-12-30 |
20210401461 | IMPLANT INSERTION DEVICE - An implant insertion device includes: an introduction needle having a needle tip that is insertable into subcutaneous tissue; an elongated implant configured to promote tissue regeneration by attachment of cells; and a tubular implant cover that covers an outer side of the introduction needle. A space extending in an axial direction is located between the implant cover and the introduction needle, and the implant is arranged in the space. | 2021-12-30 |
