<p>A hernia prothesis deployment device (10) includes an elongated rod (12) through which a drawstring (16) extends forming a loop (22) at the distal end. The size of the loop (22) is controlled by pulling on an end of the drawstring (16) extending from the proximal end of the rod (12). A Plurality of independent segments (18) are threaded onto the drawstring loop (22) in bead-like fashion, such that when the loop (22) is expanded, the loop (22) with segments (18) is flexible. When the loop (22) is contracted, the segments (18) force the loop (22) into a planar configuration. A surgical patch (28) is attached to the loop (22) such that it can be folded and pushed into position in the body. Thereafter, the loop (22) is contracted by pulling the drawstring (16) forcing the loop (22) and attached patch (28) into a planar configuration to cover the defect to be repaired.</p> |
