The invention comprises a system, method, and apparatus for securing two ends of a ruptured or partially ruptured tendon in the hand or wrist during a repair, recession, or revision procedure. During this tenorrhaphy, anchoring material is inserted into the proximal ruptured surface of the tendon by an apparatus comprising multiple needles of at least two different types. Connecting material spans the site of tenorrhaphy of a ruptured tendon, or a multiplicity of ruptured tendons. In some embodiments, interlocking patterns of loop and helical suture are inserted by straight and helical needles, respectively.

Provided herein are compositions and methods for treating a subject with damaged tissue, such as an injury associated with a tissue to tissue (e.g., a connective tissue-to-connective tissue or tissue to bone) interface. One aspect provides an adhesive film or adhesive layer, optionally comprising a biomaterial, tissue growth factors, including CTGF/CCN2, or cells.

A device for the reconstruction of the rotator cuff including a flat element having at least two opposite ends and adapted to be connected to at least one of the damaged tendons of the rotator cuff of a patient at the ends; the flat element being entirely made of biodegradable and resorbable material.

A tendon repair apparatus includes a tendon bridge having oppositely disposed proximal and distal bridge ends spaced longitudinally apart by a bridge body. A plurality of engagement legs is provided. Each engagement leg has a proximal leg end attached directly to a corresponding one of the proximal and distal bridge ends and a distal leg end spaced transversely apart from the tendon bridge. At least one receiver plate, transversely spaced from the tendon bridge and extending substantially longitudinally and laterally parallel to the tendon bridge, is provided. The receiver plate includes a plurality of receiver apertures. Each receiver aperture corresponds to a selected engagement leg. Each receiver aperture is configured to selectively engage with a corresponding selected engagement leg. Engagement between the receiver aperture and the engagement leg maintains the receiver plate in transversely spaced indirect connection with the tendon bridge.

An assembly for use in repairing a severed tendon comprises an elongate threading element adapted to transit along a lumen of a tendon sheath, for covering a curved needle and carrying the needle within the lumen. The assembly can also comprise a liner for lining an internal surface of the tendon sheath, defining an internal passage along which a tendon stump coupled to the curved needle can pass. The liner can have a collapsed, rest configuration in which it is adapted to be inserted into the lumen of the tendon sheath, and an expanded, operating configuration, the liner being movable to the expanded configuration by contact with the tendon stump. Once released from the liner, the threading element receives the curved needle, for covering and carrying the curved needle through the liner and along the lumen of the tendon sheath trailing the connected tendon stump.

Devices and methods for reconnecting or supporting torn, damaged or weak tissue are disclosed. The disclosed embodiments can be used on long slender tissue such as ligaments, tendons, nerves, vessels, intestines, muscles, bones, appendages and any other elongate tissue within the body, of both humans and other animals. The devices can wrap around elongate tissue and is capable of supporting the tissue or keeping two severed ends in close proximity to one another. The devices can be used in addition to or in lieu of sutures. The devices can function similar to a Chinese Finger Trap and are capable of decreasing in diameter upon extension, thus constricting upon the tissue. The multiple coils of the devices can make sufficient surface contact on the ligament or tendon, using friction to keep the device in place, while also allowing access for diffusion of oxygen and nutrients.

Medical constructs with collagen fibers and gelatin and related collagen fibers. The collagen fibers can be derived from extruded soluble dermal collagen and can include a gelatin film attached to the at least one collagen fiber. The gelatin film can include one or more minerals and has a gelatin concentration of between about 0.1% to about 40% weight per volume.

The present disclosure pertains to membranous tissue grafts comprising one or more pre-made attachment points. The one or more pre-made attachment points may include pre-made markings and/or pre-made suture holes. The membranous tissue grafts can be in the form of a tube. The membranous tissue grafts can also be rectangular in shape and can be used in a nerve repair by wrapping the severed or damaged nerve. In some embodiments, the membranous tissue grafts are suitable for repairing severed nerves that have a short gap or no gap with a gap of less than 5 mm between the severed stumps. Accordingly, methods are provided for repairing a damaged or severed nerve by implanting the membranous tissue grafts on to the damaged or severed nerve.

Systems and methods for fastening tissue include a hollow element and an elongate insertion element. The insertion element has a delivery device including a cone, suture, and needle at a delivery end, and an anchor at an opposite end. The hollow element includes an engagement structure in its interior surface that permits movement of the insertion element through the hollow element in a first direction, and prevents movement of the insertion element through the hollow element in a second direction opposite the first direction. The engagement structure may include a braid or mesh that operates on a finger-trap principle. The hollow element may include an elongate element with a cone, suture, and needle at a delivery end, and an anchor at an opposite end. Alternatively, the hollow element may include a button that incorporates the braid or mesh.

Devices, systems and/or methods for repairing soft tissue adjacent a repair site. In one embodiment, a repair device is delivered with a delivery device system configured to move a cartridge with the repair device disposed therein toward an anvil with soft tissue positioned thereon. The delivery device linearly moves the cartridge toward the anvil with a worm drive positioned within a housing by rotating a thumb wheel disposed around the worm drive. Such linear movement is provided with a finger element extending from the worm drive that is configured to cooperate with an internal surface of the thumb wheel. With this arrangement, upon rotating the thumb wheel, the worm drive rotates with the finger element engaged with the internal surface of the thumb wheel to linearly move the cartridge toward the anvil.
