A method, system and apparatus for augmenting the surgical repair of soft tissue injuries, in which a first end of a bridge member attaches to a first portion of healthy tissue, and a second end of the bridge member attaches to a second portion of healthy tissue. The bridge member (or bridge members) used to augment the soft tissue repair may be interconnected or function independently. Flexibility and elasticity of the bridge member are determined by the situation and may be altered to improve healing. The device may be used in arthroscopic procedures, and may be manufactured in a variety of lengths, or may be manufactured one length and be cut to the desired length, or otherwise altered to provide an optimal length of the bridge member.

Tension-slide techniques and reconstruction systems for tendon surgical repairs. The technique improves the biomechanics of the combined fixation and helps overcome surgeons' concerns about rapid return to ADLs. The technique reliably seats the tendon against the distal cortex of the bone socket, maximizing the surface area for bone to tendon healing. The technique takes advantage of cortical fixation, while providing the unique advantage of minimizing gap formation and minimizes surgical dissection by performing the surgery through a single incision technique.

An improved distraction bone screw and a method for its use are described. The distraction screw is comprised of an implantable distal segment and a detachably secured proximal segment. The distal segment includes a head portion and a threaded shank portion. The proximal segment is represented as an elongated body having an internal bore that extends through its length. A deployable member is disposed within the bore, which is extendible outside the internal bore to securely couple to the distal segment. As an assembly, the distraction screw is used to affix and realign bone during surgical reconstruction. Upon completion of the surgical work, the proximal segment is removed and the distal segment is left attached to the reconstructed bone. Securely affixed, the distal segment provides an additional point of fixation for the skeletal plates that are used to preserve the bony alignment while bone healing occurs. The affixed distal segment will also provide a ready mechanism for distraction screw replacement at the time of surgical revision without obligatory plate removal. Different embodiments of the proximal segment, distal segment and the rotational locking mechanisms which inhibit the rotation of one segment relative to the other during deployment were also described. In addition, in cases where the distraction screw must be placed into the bone at an inclined angle, poly-axial heads were provided so that proper skeletal plate placement can still be accomplished.

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.

An anterior cruciate ligament (ACL) surgical repair technique involves the use of a single femoral and tibial tunnel and an implant that separates and positions two distinct bundles. This allows for the surgeon to create a more anatomic reconstruction with a procedure that is less technically demanding, can be performed using a transtibial or anteromedial approach, minimizes tunnel widening, and decreases operative time. The result is a strong fixation option for soft tissue grafts, with circumferential graft compression at the aperture, high pull-out strength, and ease of use. The graft bundles are positioned in a more anatomic orientation through the above noted single femoral and tibial tunnel.

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.

An apparatus, method and system for the deployment of surgical mesh material, which are particularly suited for the use in the laparoscopic surgical repair of hernias. An inner actuator rod slides within a main shaft. Mesh deployment arms are connected to an end of the shaft, and a surgical mesh is mounted to and rolled around the deployment arms.
