Abstract: A surgical implantation approach for preparing a patient and precisely and effectively placing an energy absorbing apparatus relative to the patient's anatomy. Various surgical implantation apparatus and methods for achieving proper device-to-anatomy juxtapositional relationships are employed in the implantation approach.

Abstract: Implantable assemblies for manipulating energy transferred by members defining an anatomical joint, and methods of implanting and using. The members of the anatomical joint collectively define a path of motion. An assembly includes a first component configured to be attached to a first member of the anatomical joint; a second component configured to be attached to a second member of the anatomical joint; and a joint joining the first and second components. The first component includes a first flex member and the second component includes a second flex member. The first and second flex members are configured to flex to absorb energy transferred by the members of the anatomical joint.

Abstract: Various embodiments are directed to base components that are usable with implantable mechanical energy absorbing systems. According to one embodiment, the base component includes a low-profile body having a elongate, straight portion at a first end and a curved body portion at a second end. The second end is elevated as compared to the first end. An inner surface of the low-profile body has a raised portion extending along the elongate, straight portion of the low-profile body. The base component also includes a plurality of openings positioned along the low-profile body for alignment and purposes of affixation to body anatomy.

Abstract: A system and method for sharing and absorbing energy between body parts. In one aspect, the method involves identifying link pivot locations, fixing base components and minimally invasive insertion techniques. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

Abstract: Various embodiments are directed to a sheath for covering one or more components of an extra-articular implantable mechanical energy absorbing system. The sheath is generally an elongated structure having an inner space extending the length thereof. In use, the sheath can exclude the energy absorbing system from surrounding tissue and facilitate creating a capsule for its operation. Materials and dimensions are selected to achieve these purposes. The ends of the sheath include various attachment mechanisms for securing the sheath to one or more components of an extra-articular implantable mechanical energy absorbing system.

Abstract: Ankle distraction or load bypassing devices include a shoe or shoe insert that securely holds a patient's foot, and a cuff that securely holds the patient's lower leg. A load bypassing device can transmit force between the cuff and the shoe or shoe insert bypassing a portion of the load around the joint. A distraction force generating mechanism between the cuff and the shoe or shoe insert can distract the patient's ankle, while permitting the ankle to flex at a joint which joins together the cuff and the shoe.

Abstract: Implant apparatus and methods directed toward treating conditions involving the knee joint and the patella specifically are disclosed. Full range of motion of the knee joint and tissue integrity are maintained in treatment approaches involving implanting a joint surface load reducing implant proximate the joint to change the direction of the tendons or muscles exerting forces on the joints.

Abstract: A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, an anterior portion, at least one suture attachment configured to allow the patellar implant to be attached using at least one suture. The superior portion being configured to reside below a patellar tendon and to elevate and/or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes attaching the implant using at least one suture.

Abstract: Positioning instruments and related methods are described for implanting an energy absorbing system for treating joints. The positioning instruments and methods allow the energy absorbing system to be positioned at a joint such that the desired motion will occur for the particular design of a particular energy absorbing system which is to be implanted. The positioning instruments include a locating instrument for locating an anatomical feature and a target location for implantation of the energy absorbing system, a verification instrument for verification of the target location, a placement guide for guiding placement of a part of the energy absorbing system, and positioning device for aligning portions of the energy absorbing system.
