Abstract
A prosthetic implant that contains a stem integrally connected to a neck, a head that sits on top of the neck, and a porous assembly disposed around them stem. The porous assembly contains a first porous tube and a second porous tube, wherein the second porous tube is disposed within the first porous tube, and the stem is disposed within the second porous tube. The porous assembly is a heat absorbent porous assembly which tends to maintain its temperature within a specified range.
Claims12
A prosthetic implant comprised of a stem integrally connected to a neck, a head that sits on top of said neck, and a porous assembly disposed around said stem, wherein:
- a. said porous assembly is comprised of a first porous tube and a second porous tube, wherein said second porous tube is disposed within said first porous tube, and wherein said stem is disposed within said second porous tube,
- b. said porous assembly is a heat absorbent porous assembly, and
- c. said head is comprised of a load bearing spring system.
A prosthetic implant comprised of a stem integrally connected to a neck, a head that sits on top of said neck, and a porous assembly disposed around said stem, wherein:
- a. said porous assembly is comprised of a first porous tube and a second porous tube, wherein said second porous tube is disposed within said first porous tube, and wherein said stem is disposed within said second porous tube,
- b. said porous assembly is a heat absorbent porous assembly, and
- c. said heat absorbent porous assembly is comprised of a shape memory alloy.
A prosthetic implant comprised of a stem integrally connected to a neck, a head that sits on top of said neck, and a porous assembly disposed around said stem, wherein:
- a. said porous assembly is comprised of a first porous tube and a second porous tube, wherein said second porous tube is disposed within said first porous tube, and wherein said stem is disposed within said second porous tube,
- b. said porous assembly is a heat absorbent porous assembly, and
- c. said heat absorbent porous assembly is comprised of heat absorbent material and, at a temperature within the range of from about 36 to about 38 degrees Centigrade, said heat absorbent material absorbs heat and changes one of its physical properties.
A prosthetic implant comprised of a stem integrally connected to a neck, a head that sits on top of said neck, and a porous assembly disposed around said stem, wherein:
- a. said porous assembly is comprised of a first porous tube and a second porous tube, wherein said second porous tube is disposed within said first porous tube, and wherein said stem is disposed within said second porous tube,
- b. said porous assembly is a heat absorbent porous assembly, and
- c. said head is comprised of a multiplicity of solid, circular shaped objects that comprise a carbon coating disposed on the exterior surfaces of said objects.
