Patent number: 11918216Abstract: An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.Type: GrantFiled: March 21, 2022Date of Patent: March 5, 2024Assignee: COVIDIEN LPInventors: Elizabeth Contini, Kelly Valentine, Thomas Wingardner, David McCuen, Matthew Chowaniec, John Beardsley, Russell Pribanic, Xingrui Chen, Christopher Switalski

Publication number: 20220168007Abstract: In some examples, a tool for, e.g., creating a sub-sternal tunnel in a patient or other use, is described. The tool may include a handle and a tunneling shaft coupled to the handle. The tunneling shaft extends from a proximal end to a distal end, and at least a portion of the tunneling shaft extends in a curved orientation between the first end to the distal end. The distal end of the tunneling shaft includes a cutting tool having a sharp edge. The cutting tool is moveable from a recessed position in which the sharp edge of the cutting tool is recessed into the distal end of the tunneling shaft to a deployed position in which the sharp edge of the cutting tool extends beyond the distal end of the tunneling shaft in the deployed position, e.g., to cut pericardium, scar tissue, and/or connective tissue with the sharp edge.Type: ApplicationFiled: December 7, 2021Publication date: June 2, 2022Inventors: Garrett P.

Patent number: 11096683Abstract: An endoscopic stitching device includes an actuation shaft, a tool assembly, and a drive assembly. The tool assembly includes a suture needle and a pair of jaws transitionable between open and closed positions. Each jaw includes a needle engaging blade slidably supported thereon. Each needle engaging blade is transitionable between an extended position in which the needle engaging blade engages the suture needle and a retracted position in which the needle engaging blade is disengaged from the suture needle. The drive assembly includes first, second, and third electrical actuators. The first actuator is operatively coupled with the actuation shaft to cause axial displacement of the actuation shaft. The axial displacement of the actuation shaft causes opening and closing of the pair of jaws. The second and third actuators are operatively coupled with the needle engaging blades to provide axial displacement of the needle engaging blades.Type: GrantFiled: April 2, 2019Date of Patent: August 24, 2021Assignee: Covidien LPInventors: Stanislaw Marczyk, Russell Pribanic, Anthony Calderoni, Christopher Switalski
