Abstract
Abstract Apparatus and method for laparoscopic hernia repair including the use of an introducer sheath housed around an inner tubular plunger. The plunger houses an elongated ribbon formed into a loop, the loop being formed by a bipartite distal end of the ribbon. A patch with a passageway is attached to the loop with each of the two ends of the bipartite distal end of the ribbon being introducible into one end of the passageway for opening the patch into a planar configuration once it is pushed out of the sheath by the plunger.
