Abstract

A hernia patch has a first layer of inert synthetic mesh material selectively sized and shaped to extend across and beyond a hernia. A second layer of inert synthetic mesh material overlies the first layer to create a generally planar configuration for the patch. The first and second layers are joined together by a seam that defines a periphery of a pouch between the layers. One of the layers has a border that extends beyond the seam and has a free outer edge. A plurality of border slits extend from the outer edge through the border substantially to the seam. Access slits are formed between the layers to allow insertion of a surgeon's finger into the pouch. The pouch allows the surgeon to deform the planar configuration of the patch to facilitate insertion of the patch into the patient and to position the patch across the hernia. A resilient monofilament I-shaped spring is located within the pouch at the seam for urging the patch to conform to the generally planar configuration across the hernia as the surgeon withdraws his or her finger.
