A method for repairing a hernia uses a mesh patch for permanent placement within a patient's body space. The patch has top and bottom mesh layers secured to each other with a seam. The seam surrounds and defines a pocket. The top layer has a transverse slit opening into the pocket. To serve a spring function, an implantable loop is inserted into the pocket to keep the patch expanded under tension in a planar configuration. A border on at least one of the layers extends outward past the seam. The border preferably has slits to fill uneven voids in the patient's tissue and fit more tightly. A surgeon makes a small incision in the patient and performs a dissection deep into the patient's preperitoneal space, creating a pocket in this space into which the patch is to be inserted. The patch is folded and directed into the patient's preperitoneal space, where it is unfolded and expanded into its planar configuration to cover the defect in the patient. Thereafter the surgeon secures the incision with stitches.

[ What is claimed is:] [1.]1. A method of repair of an abdominal wall hernia, comprising the steps of:(a) cutting an incision obliquely positioned above the location described as the internal ring where the hernia has occurred, the cutting extending through the patient's skin, subcutaneous fatty tissues, and the external oblique fascia, which is cut parallel with the fibers thereof a short distance to expose the underlying internal oblique muscle;(b) separating portions of the internal oblique muscle to in turn expose the transversalis fascia;(c) cutting the transversalis fascia to create an entrance into the preperitoneal space above the peritoneum at a location above the hernia;(d) identifying and freeing the hernia sac;(e) creating a pocket in the preperitoneal space;(f) providing a hernia mesh patch made of a first layer to extend across and beyond a hernia, and a second layer secured to the first layer to create a pouch therebetween, the pouch having an opening for the insertion of a finger of a surgeon, and a resilient support member located in the pouch that creates tension throughout both layers;(g) folding and compacting the hernia mesh patch;(h) directing the folded and compacted hernia mesh patch down through the incision and beyond into the preperitoneal space;(i) expanding the hernia mesh patch in the preperitoneal space by positioning it so the support member freely creates the tension throughout both layers;(j) inserting a finger of the surgeon through the incision and beyond to the transverse slit and into the pouch of the hernia mesh patch;(k) directing the hernia mesh patch through the preperitoneal space and into the pocket by the hernia;(l) withdrawing the finger from the hernia patch and back up through the incision such that the support member remains implanted in the patient; and(m) closing the incision with stitches.
