A prosthetic mesh and method of use in surgical methods for closure of abdominal incisions and prosthetics for repair of ventral hernias. The mesh provides for a new prosthetic that can be used for closure of laparotomy incisions, in patients at high risk for hernia formation, and in the repair of existing ventral hernias. The mesh utilizes existing multi laminar technology for intra peritoneal mesh, and fashions it in the shape of an intact Rectus Sheath. The mesh matrix can be made of any of the various absorbable or permanent polymer filaments that are woven or knitted into a scaffold for added strength to the abdominal wall closure during the healing phase, and for delivery of bio active substances that contribute to a biochemical milieu that contributes to favorable healing. A permanent non absorbable prosthesis will be desirable in certain circumstances and for particular patients, a slowly dissolving mesh would be ideal in most cases. The absorption of the prosthesis must be slow, approximately one to two years, thus giving enough time to preserve support for the healing abdominal wall repair, as this is the period of time over which most incisional hernias present.
