Systems, apparatus, and methods are provided for promoting blood flow to a target tissue. In one aspect, the invention involves canalizing or boring channels, divots, trenches or holes through an avascular connective tissue, or through a tissue having sparse vascularity, such as a tendon or a meniscus, in order to increase blood flow within the tissue. In one method, an active electrode is positioned in close proximity to a target site on a tendon, and a high frequency voltage difference is applied between the active electrode and a return electrode to selectively ablate tendon tissue at the target site, thereby forming a channel or void in the tendon. The active electrode(s) may be moved relative to the tendon during, or after, the application of electrical energy to damage or sculpt a void within the tendon, such as a hole, channel, crater, or the like. In another aspect of the invention, an electrosurgical probe is used to elicit a wound healing response in a target tissue, such as an injured tendon, in order to stimulate vascularization of the target tissue. The present invention may also be used for vascularization of a torn or damaged tissue in conjunction with a surgical repair procedure.

It is described a construct for use in surgical repair of tendon. The construct contains at least one layer of human amnion and chorion tissues and is generally cylindrical with a C-shaped cross-section to allow for ease of implantation over the tendon. Methods for preparing the construct is described. In addition, an improved method for surgical repair of a damaged or diseased tendon using the construct is also described. The improved method reduces adhesions, scar formation, inflammation and risk of post-operative infection.

Surgical anchoring systems and methods are employed for the correction of bone deformities. The anchoring system and its associated instrument may be suitable for surgical repair of hallux valgus, tarsometatarsal sprains, ankle ligament reconstruction, spring ligament repair, knee ligament reinforcement, acromioclavicular sprains, coracoclavicular sprains, elbow ligament repair, wrist and hand ligamentous stabilization or similar conditions. The anchoring system may include a fixation system for anchoring two or more sections of bone or other body parts and a system for aligning of one section relative to another section.

Interposition and augmentation devices for tendon and ligament repair, including rotator cuff repair, have been developed as well as methods for their delivery using arthroscopic methods. The devices are preferably derived from biocompatible polyhydroxyalkanoates, and preferably from copolymers or homopolymers of 4-hydroxybutyrate. The devices may be delivered arthroscopically, and offer additional benefits such as support for the surgical repair, high initial strength, prolonged strength retention in vivo, flexibility, anti-adhesion properties, improved biocompatibility, an ability to remodel in vivo to healthy tissue, minimal risk for disease transmission or to potentiate infection, options for fixation including sufficiently high strength to prevent suture pull out or other detachment of the implanted device, eventual absorption eliminating future risk of foreign body reactions or interference with subsequent procedures, competitive cost, and long-term mechanical stability. The devices are also particularly suitable for use in pediatric populations where their eventual absorption should not hinder growth.

Knotless fixation of soft tissue to bone is accomplished using a bone anchor configured to provide interference fixation of a soft-tissue connector. The soft-tissue connector is provided in the form of a flat narrow piece of material. Additional fixation strength can be provided by configuring the bone anchor to penetrate into or through the soft-tissue connector. The bone anchor is installed into a pre-formed hole or socket in the bone.

A method and device for finding isometric points in the joints of mammals for use in surgical repair of a joint. Isometric points are first identified in radiographic or other two dimensional images and then located in the actual joint. A method for repairing a cruciate ligament-deficient canine stifle employing the method and device for finding isometric points is described. A method and apparatus for locating the axis of rotation of a joint is also described.
