Devices, systems and / or methods for repairing a lacerated tendon or ligament adjacent a repair site. In one embodiment, a repair device includes an elongated flexible structure and multiple anchors, the multiple anchors pre-positioned with the elongated flexible structure. The repair device may be coupled to the tendon or ligament at the repair site with a delivery device. The repair device may be pre-positioned in a cartridge such that the cartridge is loaded into the delivery device. The lacerated tendon or ligament is positioned within a cradle portion of the delivery device such that the tendon is positioned between the cradle portion and the cartridge that holds the repair device. The delivery device may then be triggered to actuate and drive the repair device from the cartridge to couple to the lacerated tendon or ligament. In this manner, the repair device may be anchored to the lacerated tendon.

An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch and / or plug having a body portion that is larger than a portion of the opening or weakness so that placement of the body portion against the defect will cover or extend across that portion of the opening or weakness. At least one tether, such as a strap, extends from the patch or plug and may be manipulated by a surgeon to position the patch or plug relative to the repair site and / or to secure the patch or plug relative to the opening or weakness in the tissue or muscle wall. The tether may be configured to extend through the defect and outside a patient's body to allow a surgeon to position and / or manipulate the patch from a location outside the body. An indicator may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and / or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and / or positioning of the patch or plug over the opening or weakness.

Apparatus and methods for repairing damaged tendons or ligaments. Various repair apparatus include an elongate tensile member and a pair of anchor structures connected for movement along the tensile member on either side of a repair site, such as a tear or laceration. The anchor structures may take many forms, and may include barbed, helical, and crimp-type anchors. In the preferred embodiments, at least one anchor structure is movable along the elongate tensile member to assist with adjusting a tendon segment to an appropriate repair position and the anchor structure or structures are then lockable onto the elongate tensile member to assist with affixing the tendon at the repair position. Tendon-to-bone repair apparatus and methods are also disclosed employing similar concepts. Tendon retrieval devices include helical members for rotating into a tendon end and subsequently moving the tendon to an appropriate operating position.

A cartilage plug, which is made from a biocompatible, artificial material, that is used to fill a void in natural cartilage that has been resected due to traumatic injury or chronic disease is disclosed. Alternatively, the plug may be relied upon to anchor a flowable polymer to subchondral bone. The plug is prefabricatable in any size, shape, and contour and may be utilized either singly or in a plurality to fill any size void for any application. The plug may be formed of a laminated structure to match the physiological requirements of the repair site. Additionally, ridges may be formed about the periphery of each plug to facilitate its anchoring to surrounding cartilage, bone and / or adjacent plugs. A procedure for resecting damaged or diseased cartilage and for implanting a replacement plug or plugs according to this invention, as well as a set of instruments for effecting the procedure, and a self-contained system for orthopaedic surgeons, which includes a variety of differently sized and shaped plugs, as well as a set of instruments for the procedure are also disclosed.

A device for mixing and delivering a mixture of fluids to a target site includes a tube for containing the mixture. A compressible auger for mixing the fluids is movably disposed within the tube, one end of the auger being free at the distal end of the tube. A plunger is also movable within the tube in communication with the other end of the auger. When the plunger is moved axially within the tube the auger also moves axially and the auger is compressed to dispense the fluid. The mixing and delivery device can be used with an apparatus for the arthroscopic delivery of a tissue repair material to a repair site. The apparatus includes a first sheath and a second sheath removably attached to the first sheath for delivering the tissue repair material to the repair site.

An implantable prosthesis for repairing an anatomical defect, such as a soft tissue and muscle wall defect. The prosthesis is configured to reduce the likelihood that an applied force at the repair site, such as due to intraabdominal pressure or tissue shrinkage, can lead to detrimental effects associated with tension at the anchoring locations between the prosthesis and host tissue and / or contraction of the prosthesis. In this regard, the prosthesis may be configured to limit the amount of tension at the anchoring locations caused by the application of a force or pressure to the prosthesis and / or contraction of the prosthesis. Alternatively, the prosthesis may be configured to compensate for contraction of the prosthesis due to tissue shrinkage at the repair site. The prosthesis may be configured to both limit tension at the anchoring locations and compensate for tissue shrinkage. The prosthesis may facilitate a reduction in postoperative discomfort, a recurrence of the defect, or the creation of a new defect associated with tension and / or prosthetic contraction.
