Abstract
A system for manipulating energy transferred by members defining a joint and a method of implantation includes a first attachment structure configured to be attached to a first member of the joint and a second attachment structure configured to be attached to a second member of the joint.
Claims23
A method of implanting a medical device at an interventional site of a patient, comprising:
- implanting a first component at the interventional site;
- inserting a second component attached to a temporary component at the interventional site between the first and second components;
- implanting the second component at the interventional site;
- assessing kinematic characteristics for a link component based upon the configuration of the temporary component between the first and second components;
- and
- removing the temporary component from the interventional site.
A method of implanting a medical device across an articulating knee joint, comprising:
- viewing a femur and a tibia of the articulating joint from a side vantage point;
- positioning a bulls-eye at a position of an approximate center of rotation of the femur;
- positioning a first guide generally perpendicular to the femur;
- inserting a first K-wire into the femur through the guide;
- and
- configuring a pivot hole of a first base component over the first K-wire.
An implantable system for manipulating energy transferred by members defining a knee joint including ligaments attached there across, 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 absorber attached to the first attachment structure and second attachment structure, the absorber including three springs;
- wherein energy manipulated by the absorber is in a direction opposite from any forces absorbed by the ligaments.
An implantable system for manipulating energy transferred by members defining a knee joint including ligaments attached there across, 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 absorber attached to the first attachment structure and second attachment structure, the absorber including at least one spring and at least one spherical bearing;
- wherein the absorber applies a force to the bones of the joint in a direction opposite from forces applied by the ligaments of the joint;
- and
- wherein at least one screw of the first attachment structure and the second attachment structure passes through the spherical bearing.
