  • Patent number: 11419607
    Abstract: A mechanical system for bilaterally securing skin tissue preferably utilizes a tissue manipulator apparatus to approximate a portion of an interior surface of each of two pieces of living dermis tissue along a vertical interface below an exterior surface without overlapping either interior surface across the vertical interface. An applicator apparatus includes a driving head portion positioned in the vertical interface and at least partially below the exterior surface and a handle portion positioned at least partially above the exterior surface. The applicator apparatus bilaterally drives at least one portion of the fastener through each piece of the living dermis tissue behind the interior surface of that piece of tissue such that the fastener is positioned below the exterior surface and a portion of the fastener is positioned generally transverse to the vertical interface. The applicator can include guide features to direct tissue with respect to the driving head portion.

  • Patent number: 11045196
    Abstract: A staple drive assembly includes an actuation sled and at least one staple pusher. The staple drive assembly is adapted to fit within a staple cartridge having a plurality of staples and a corresponding number of retention slots. The at least one staple pusher includes at least one pusher plate for releasably engaging a backspan of a staple. The staple pusher may include a plurality of pusher plates that may be laterally and longitudinally spaced apart. An actuation member has at least one angled camming surface for engaging a complimentary angled surface of the at least one staple pusher. Camming engagement between the actuation member and the at least one staple pusher causes vertical movement of the at least one staple pusher. Lateral and longitudinal offset of the actuation member camming surfaces and the corresponding staple pusher following surfaces improves stability and control of the staple pusher during firing.

  • Patent number: 10945726
    Abstract: The invention provides a fastening device for laparoscopic hernia repair. The coordinated operation of two insertion members stabilizes a fastener during closure and locking to ensure that the fastener is locked in the intended location before the device releases from the fastener. One of the insertion members includes a pair of prongs that exhibit a closed configuration when they are disposed in a recess at an end of the fastener. The fastener has a hook at one end and a loop at the other end. The insertion members push the fastener out from the device and through the tissue. A curvature in at least one of the insertion members pushes the hook through the loop all while the prongs are in the recess in the fastener, thereby stabilizing the fastener with respect to the device.
