A surgical apparatus for anchoring and reattachment of torn tissue such as a rotator cuff against on the outer or exterior surface of a tissue substrate. The invention includes a tissue substrate anchor such as that having expandable wings, an elongated suture member securable at its proximal end to the tissue substrate anchor, and a torn tissue retainer lockingly attachable along the length of the suture member by mating interlocking structure therebetween. Tension is applied to the free distal end of the suture member while the tissue retainer is non-reversibly moved longitudinally along on the suture member to secure the torn tissue against the tissue substrate outer surface. A separate torn tissue gripping member may also be provided for broadened and enhanced torn tissue securement against the tissue substrate. In another embodiment, the tissue anchor is formed as a unit with the suture member enabling additional forms of tissue repair such as the closure of an internal meniscus tear or separation.

Torn tissue such as a rotator cuff is positioned on the bone exterior by a tissue grasper. A cannula is inserted through the skin substantially to the torn tissue. A drill guide is inserted into the cannula, a drill bit is inserted into the drill guide, and a hole is drilled through the torn tissue and completely through the bone. The drill bit is removed and an inner cannula is passed through the drill guide until its distal end is engaged on the torn tissue or alternatively passed through the hole until its distal end is at the far end of the drilled hole. A soft tissue anchor having expandable wings at its distal end and sutures secured to an eyelet at its proximal end is releasably connected to the distal end of a tubular deployment tool with the free ends of the sutures extending through the deployment tool. The deployment tool is passed through the inner cannula and drilled hole until the expandable wings clear the far end of the hole a sufficient distance to allow the wings to expand to a diameter larger than the diameter of the drilled hole. The deployment tool, inner cannula, drill guide, and cannula are removed and tension is applied to the suture to engage the expanded wings of the anchor on the exterior surface of the bone surrounding the drilled hole.

606232

A surgical suture system, suture, and tissue engaging member for tissue repair and reattachment of torn tissue to a tissue substrate, medical prosthesis or medical implant. The system includes the elongated flexible suture member having a plurality of longitudinally spaced protuberances along a length thereof and one or a plurality of the tissue engaging members each of which include two closely spaced apart locking apertures sized and configured to receive one of the suture members passed therethrough or a unique single locking aperture to allow longitudinal tensioning and/or restraining movement of the suture member in only one direction through the locking apertures for suture member tightening.
