Abstract
Apparatus and methods for forming pilot holes in bone and deploying a staple therein for fixing a sheet-like implant to the bone. A pilot hole forming trocar assembly including a trocar and a position retention sleeve can be included. The trocar can be releasably coupled to the position retention sleeve and slide in keyed arrangement within the sleeve when uncoupled. The trocar can include a distal portion having a retractable blade and a pair of pilot hole forming spikes extending distally from the trocar shaft. Once the pilot holes are formed, the position retention sleeve maintains the position relative to the pilot holes while the trocar is removed and a staple delivery device can be inserted in the lumen of the position retention sleeve to deploy a staple in the pilot holes.
