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.
