Abstract
A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system is an unlinked structure which facilitates absorbing energy between members forming a joint such as between articulating bones.
Claims42
An implantable knee unloading device for a knee comprising:
- a first member configured to be affixed to a first member of a knee joint;
- a second member configured to be affixed to a second member of the knee joint;
- mating portions of the first and second members configured to contact one another to transmit force between the first and second members, wherein the mating portions are not connected to one another;
- wherein motion between the mating portions is confined to primarily pivoting motion, without substantial translating motion;
- and
- wherein the knee unloading device is configured to be implanted outside of the joint capsule and to absorb at least a portion of the total load applied to the knee during at least 5 degrees and during no more than 90 degrees of a natural range of motion of the knee.
3 more elements
An implantable knee unloading device comprising:
- a first member configured to be affixed to a first member of a knee joint;
- a second member configured to be affixed to a second member of the knee joint;
- mating portions of the first and second members configured to contact one another to transmit forces between the first and second members, wherein the mating portions are not connected to one another;
- and
- wherein the entire knee unloading device is configured to be implanted entirely outside of the articulating surfaces of the knee.
2 more elements
A method of treating a knee joint, comprising:
- attaching a first member to a first bone of the knee joint;
- attaching a second member to a second bone of the knee joint;
- arranging the first and second members so that they are entirely outside of articulating surfaces of the knee joint, forces are translated from the first member to the second member and the first and second members are not linked to each other.
An implantable load manipulating device for an articulating joint comprising:
- a first member configured to be affixed to a first member of a joint;
- a second member configured to be affixed to a second member of the joint;
- the first and second members configured to have a load manipulation state and a passive state wherein during the load manipulation state the first and second members are configured to form a continuous structure external to the joint and when in a passive state the first and second members form a discontinuous structure;
- and
- wherein during the continuous state the device is capable of transmission across the joint and during the discontinuous state the device is incapable of transmission load across the joint.
2 more elements
An implantable knee unloading device for a knee, comprising:
- a first member configured to be affixed to a first member of a knee joint;
- and
- a second member configured to be affixed to a second member of the knee joint, the second member comprising a mating portion comprising a flexible tension member extending between two arms, wherein mating portions of the first and second members are configured to contact one another to transmit forces between the first and second members, and the mating portions are not connected to one another.
An implantable knee unloading device for a knee, comprising:
- a first member configured to be affixed to a first member of a knee joint;
- and
- a second member configured to be affixed to a second member of the knee joint, the second member comprising a mating portion comprising a resilient, flexible ring, wherein mating portions of the first and second members are configured to contact one another to transmit forces between the first and second members, and the mating portions are not connected to one another.
An implantable knee unloading device for a knee, comprising:
- a first member comprising a first base configured to be affixed to a first member of a knee joint;
- and
- a second member comprising a second base configured to be affixed to a second member of the knee joint, wherein first and second mating portions of the first and second members, respectively, are configured to contact one another to transmit forces between the first and second members, the first and second mating portions are not connected to one another, and a resilient member is disposed between at least one of the first mating portion and the first base and the second mating portion and the second base.
An implantable knee unloading device for a knee, comprising:
- a first member comprising a first base configured to be affixed to a first member of a knee joint;
- and
- a second member comprising a second base configured to be affixed to a second member of the knee joint, wherein first and second mating portions of the first and second members, respectively, are configured to contact one another to transmit forces between the first and second members, the first and second mating portions are not connected to one another, one of the first mating portion and the second mating portion comprising a spring beam.
