Abstract
Abstract A surgical crimping instrument for crimping a sleeve including an anvil and a hammer moveable relative to each other to crimp the sleeve, a pusher movable longitudinally and engaging the hammer and/or anvil for urging the hammer and the anvil together as the pusher moves longitudinally from a first position to a second position, and cooperative stops adjacent to the hammer and the anvil for limiting the relative movement of the hammer towards the anvil.
