Abstract
A tissue aperture repair device which is inserted using either an openly or minimally invasive surgical procedure for at least partially covering a tissue aperture or hernial ring. The repair device includes a foldable sheet of material that is maintained with support means in an unfolded shape. The support means includes a second sheet of material attached to the circumference of the foldable sheet for forming a cavity therebetween. An elastic stiffener wire is inserted into the cavity for maintaining the device in its unfolded shape. Percutaneous insertion of the device is accomplished with the inclusion of an introducer in which the device is folded about the distal end thereof and contained within a containment sheath. The device is percutaneously inserted into the abdominal cavity of a patient, unfolded, and extended to the unfolded shape with an elastic stiffener wire also percutaneously inserted through the introducer. The device is attached to tissue surrounding the hernial ring using suture material or helical coil fasteners. Alternatively, the device is fastened using an affixation suture extending from the foldable sheet of material.
