Implantable tissue repair device
View Patent ↗An implantable tissue repair device has a cover and tissue regeneration material. The cover includes a top panel and a bottom panel joined together along a leading edge. The tissue regeneration material is positioned between the top and bottom panels. The cover includes a continuous sheet of biocompatible material extending across the edge and into the top panel and bottom panel. The cover is thicker along the leading edge than at least a portion of the top panel and thicker than at least a portion of the bottom panel. At least a portion of one of the panels covering the tissue regeneration material is thicker than a portion of the other panel covering the tissue regeneration material. A method of making the device is also disclosed.
