1. An implant delivery system for delivering a sheet-like implant, the implant delivery system comprising:
an elongate insertion portion having a proximal end and a distal end, said insertion portion defining a generally longitudinal direction; an implant holder assembly proximate the distal end of the elongate insertion portion, the implant holder assembly comprising a first leg and a second leg each having a proximal and a distal end with the proximal end of each leg pivotably coupled to the distal end of the elongate insertion portion, the first and second legs moveable between a closed position and an open position wherein in the closed position the legs extend generally in the longitudinal direction and in pivoting to the open position the distal end of each leg moves in a generally transverse direction; and a sheet-like implant coupled to the implant holder assembly, wherein the sheet-like implant is folded when the legs of the implant holder assembly are in the closed position and unfolded when the legs of the implant holder assembly are in the open position to spread the sheet-like implant positioned on the implant holder assembly such that the sheet-like implant has a generally planar configuration that is substantially parallel to an axis defined by the longitudinal direction of the elongate insertion portion. |
