A system and surgical methods for repairing tears in meniscal tissue using meniscal darts. In a preferred embodiment, the system includes a cannulated insertion sheath, a meniscal dart, and a disposable dart driver preloaded with a meniscal dart at its distal end. The insertion sheath is located near a meniscal tear, and sharp prongs on the tip of the sheath are used to secure and position the central fragment of the torn meniscus. The dart driver with a preloaded dart is advanced through the cannulation of the insertion sheath such that the preloaded meniscal dart at the distal end of the driver is inserted through the meniscal tear.

A biocompatible meniscal repair device is disclosed. The tissue repair device includes a scaffold adapted to be placed in contact with a defect in a meniscus, the scaffold comprising a high-density, dry laid nonwoven polymeric material and a biocompatible foam. The scaffold provides increased suture pull-out strength.

A device for repairing a tear in a portion of tissue comprises a proximal actuator portion, a transfer needle extending distally from the proximal actuator portion and a catch needle extending distally from the proximal actuator portion. A suture needle is disposed in the transfer needle, and is extendable from the transfer needle toward the catch needle and retractable from the catch needle toward the transfer needle. An extendable catch plunger is disposed in the catch needle for capturing suture therein when it is transferred from the transfer needle. A retractable insertion sheath is provided for covering the transfer needle and the catch needle when the device is inserted into a procedural site. A depth limiting apparatus limits the depth of insertion of the needle into the procedural site.

Biologic partial menisci (biologic partial meniscal replacements / constructs) used to replace at least a part of a meniscus, and methods of forming such biologic partial menisci. Meniscal cartilage is employed to form a moldable allograft paste. A sterile mold that replicates a meniscus (for example, the medial or lateral meniscus) is provided in various sizes and is used as a biologic mold to recreate the anatomic shape of the meniscus. The moldable paste is inserted (for example, injected) into the mold and allowed to set into a stable, anatomically shaped meniscus (the biologic partial meniscus). Fibrin glue or other biologic adhesives or strengtheners may be optionally added to provide further biomechanical strength. Once the biologic partial meniscus is removed from the mold, it is provided at the surgical site and attached to the excised meniscus (placed into the correct anatomical shape) to complete the meniscal repair.

A surgical fastener system that utilizes a very intense electrical discharge in a captured fluid volume to cause fluid vaporization thereby to drive a fastener body distally from an open-ended channel in an introducer member. More in particular, the fastener system comprises proximal and distal fastener components that are carried in a channel in an introducer. The proximal fastener component is a fluid sealed in a volume proximal to the head of a fastener body. The distal component of the fastener system is the fastener body itself, which typically defines a head portion and extending leg portion. The system further provides a high voltage electrical source coupled to 1.sup.st and 2.sup.nd electrode terminations that are in substantial contact with the captured fluid volume. Upon actuation of a switch mechanism, an electrical discharge is induced between the 1.sup.st and 2.sup.nd electrodes which causes an intense thermal effect within the captured fluid which generates a vapor bubble therein. The explosive expansion pressures caused by such bubble formation thereby imparts driving forces against the fastener body to drive the fastener outwardly into or through the targeted structure. The driving force applied to the fastener head can be selected by controlling the power level of the electrical discharge.

A method for in situ repair of meniscal injuries comprising induction of meniscal repair and regeneration by introducing an adhesive collagen-polyethylene glycol (PEG) hydrogel to a site of injury alone, supplemented with a synovial tissue or in conjunction with a support matrix.

The present application discloses a bidirectional suture passing instrument arranged to vertically approach soft tissue, enabling safer and more efficient surgical repair, using minimally invasive techniques, and can be used, for example, in annulus repair, meniscus repair, shoulder arthroscopy Examination, hernia repair, laparoscopic repair and wound closure.

An assembly for meniscal repair including a first tissue fixation member configured to secure a meniscal tissue, a suture anchor having a proximal end, a distal end, a central axis defined therethrough, an eyelet on the proximal end of the suture anchor, and a textured outer surface, and a first suture configured to be coupled to the first tissue fixation member and configured to be received through the eyelet of the suture anchor.

Shaped constructs for repair of a defect in a body part or tissue of a subject are discussed herein. More specifically, implants suitable for delivery to a subject, such as a subject having a defect in a body part or body tissue, are discussed. Even more specifically, implants for intervertebral disc repair comprising corticocancellous bone, which can extend into the nucleus pulposus of an intervertebral disc and can be integrally attached to the annulus fibrosus of the disc to keep the implant in position, are described. Also, implants for meniscal repair comprising corticocancellous bone, which can extend from the outer edge of the meniscus to the inner region of the meniscus and can be integrally attached to the meniscal rim to keep the implant in position, are described. Implants for the repair of defects in bone, cartilage, and fibrocartilage are further described. Further described are methods for making such implants and for delivering the implants to a defect in a body part or body tissue of a subject.

An arthroscopic needle having partial cuts or serrations along one side of a circular, hollow needle shaft allows the needle to bend, or articulate, by drawing a pull strip bar, defined by a thin strip along the interior side closet to the serrations in the hollow shaft, for compressing along the cuts to draw uncut segments into closer arrangement for curving the needle in the direction of the compressed side. The selectively articulating, or "bendable" needle that curves in response to a rotating knob provides for insertion of surgical attachment anchors in difficult-to-reach areas of meniscal tissue. The disclosed articulating needle has the ability to bend and access more anterior and posterior zones of meniscal repairs than conventional rigid needle approaches.
