Abstract: A method of repair of direct space and indirect space inguinal hernias and a unique prosthesis enable the use of laparoscopic surgical techniques with the benefits associated therewith, while greatly reducing the recurrence of hernial defects. The prosthetic device in accordance with the present invention is a unitary piece having an abdominal wall engaging base, a hollow projection, and a slurry retaining flap. The base includes a flange that anchors the prosthetic device against the abdominal wall and a flange that covers and gives support to the surrounding abdominal wall where direct space inguinal hernia recurrence is high. The projection, situated between the ledge and the flange, is received within the defect associated with inguinal hernias and lends support thereto.
