Abstract
A system for manipulating energy transferred by members defining a joint. The system 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. There is also an adjustable energy absorbing device attached to the first attachment structure and second attachment structure, wherein adjusting the energy absorbing device changes the load manipulating characteristics of the energy absorbing device.
Claims14
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 assemblies, wherein the adjustable assemblies comprise a plurality of nonthreaded teeth and a locking collar configured to contact the teeth to lock the adjustable energy manipulation device into a position corresponding to a loading characteristic, and wherein the adjustable energy manipulation device includes at least one spring and the adjustable assemblies adjust a size of the energy manipulation device to affect an amount of compression in the spring.
An implantable system for manipulating energy transferred by members defining a knee joint, comprising:
- a first attachment structure configured to be attached to a first member of the knee joint;
- a second attachment structure configured to be attached to a second member of the knee joint;
- and
- an adjustable energy manipulation device including at least one spring, the adjustable energy manipulation device being attached to the first attachment structure and second attachment structure, the adjustable energy manipulation device including one or more adjustable assemblies for adjusting a size of the energy manipulation device to affect an amount of compression in the spring, wherein the adjustable energy manipulation device permits expansion of the spring to no more than a maximum expansion position and compression of the spring to no more than a maximum compression position that is spaced at a compression distance from the maximum expansion position, and wherein adjusting the size of the energy manipulation device adjusts a size of the maximum compression distance.
An implantable system for manipulating energy transferred by members defining a knee joint, comprising:
- a first attachment structure configured to be attached to a first member of the knee joint;
- a second attachment structure configured to be attached to a second member of the knee joint;
- and
- an adjustable energy manipulation device including at least one spring, the adjustable energy manipulation device being attached to the first attachment structure and second attachment structure, the adjustable energy manipulation device including one or more adjustable assemblies for adjusting a size of the energy manipulation device to affect an amount of compression in the spring,
- wherein the adjustable assembly includes a ball attached to the energy manipulation device and the ball includes an extension including teeth.
An implantable system for manipulating energy transferred by members defining a knee joint, comprising:
- a first attachment structure configured to be attached to a first member of the knee joint;
- a first socket of a first ball and socket joint removably attached to the first attachment structure;
- a second attachment structure configured to be attached to a second member of the knee joint;
- a second socket of a second ball socket joint removably attached to the second attachment structure;
- and
- an energy manipulation device including at least one spring, a first ball and a second ball, wherein the energy manipulation device is attached to the first and second attachment structures by the first and second balls, wherein the energy manipulation device includes one or more adjustable assemblies for adjusting a size of the energy manipulation device to affect an amount of compression in the spring, wherein the adjustable energy manipulation device permits expansion of the spring to no more than a maximum expansion position and compression of the spring to no more than a maximum compression position that spaced at a compression distance from the maximum expansion position, and wherein adjusting the size of the energy manipulation device adjusts a size of the maximum compression distance.
