  • Publication number: 20170035417
    Abstract: An applicator instrument for dispensing surgical fasteners includes a housing having an actuator and an elongated shaft extending from the housing. The applicator instrument includes a top stamping disposed within the elongated shaft, and a bottom stamping disposed within the elongated shaft that opposes the top stamping. The applicator instrument has a firing system for dispensing at least one surgical fastener from the distal end of the elongated shaft. An end cap is assembled with the distal ends of the top stamping, the bottom stamping, and the elongated shaft for stabilizing the distal end of the applicator instrument. The end cap has a distal end face with castling for engaging an opposing surface such as surgical mesh overlying tissue. The castling prevents the distal end of the applicator instrument from sliding or moving relative to the opposing surface.

  • Patent number: 9498211
    Abstract: A method of securing a prosthetic device to tissue includes providing an applicator instrument including a housing, a shaft, surgical fasteners, a firing rod for dispensing the surgical fasteners from the shaft, a trigger, and an energy storing element. The method includes positioning a prosthetic device over tissue, juxtaposing a distal end of the shaft with the prosthetic device, and compressing the trigger for piloting the firing rod toward the distal end of the elongated shaft at a first rate of speed. The method includes preventing the firing rod from moving distally while building up energy in the energy storing element, and further compressing the trigger for releasing the firing rod for distal movement and transferring the built up energy for moving the firing rod toward the distal end of the elongated shaft at a second rate of speed that is greater than the first rate of speed.
