Abstract:
1. An implantable system for manipulating energy transferred by members defining a joint, comprising: a first attachment structure configured to be attached to a first member of the joint; a second attachment structure configured to be attached to a second member of the joint; and an adjustable energy manipulation device attached to the first attachment structure and second attachment structure, the adjustable energy manipulation device includes one or more adjustable link assemblies, the energy manipulation device comprises a shaft attached to a first base, an outer component attached to a second base, wherein the shaft translates inside of the outer component, a spring mounted coaxial with the shaft and outer component, the spring and outer component providing no limitation or resistance to extension of the energy manipulating device by translation of the shaft within the outer component; wherein a lesser amount of energy manipulation occurs as the members defining the joint move from their extension position through greater degrees of flexion.
