Abstract: A repair prosthetic for repairing a hernia is disclosed. In some embodiments, the repair prosthetic includes a patch body, a frame that assists in spreading the patch body from a reduced configuration to an expanded configuration, and a plurality of tethers attached to the patch body at locations between the frame and a periphery of the patch body. In various embodiments, the tethers can be tensioned to mitigate curling or creasing in the patch body to flatten the patch to facilitate attachment to tissue.

Abstract: There is disclosed a method, apparatus and system for in situ relining underground pipes, lines and passageways particularly sewer lines. A sewer line which has deteriorated and/or otherwise requires repair is cleaned in a conventional manner by use of high pressure water jets to dislodge debris and clean the line, a T.V. inspection of the line is made to determine where the defects are located and to make a log of all ties and intersects. A moisture barrier, such as a thin polyethylene film, is installed along with a resin impregnable felt liner, the polyethylene film serving to prevent absorption of water or other moisture or contaminant by the felt liner and permitting thereby full absorption of resin by the liner. With the upstream end of the felt tube molded or otherwise sealed to the existing end of the sewer line a steel rod is then passed through the inside of the felt liner between the two points between which the repair is being made.
