Claims33
A bone-implantable prosthetic device, comprising:
- an interface portion operative to interface the bone-implantable prosthetic device with an other structure;
- and
- a stem coupled to said interface portion, wherein the stem is structured for implantation to a desired depth into a bone tissue, and wherein the stem includes:
- a pin, fin and/or lattice structure operative to interface with bone tissue for load transfer between said stem and the bone tissue.
A prosthetic implant, comprising:
- an interface portion operative to interface with an other structure;
- and
- a stem coupled to said interface portion, wherein the stem is structured for implantation to a desired depth into a bone tissue, and wherein the stem includes:
- a hollow body having an outer ring structure, wherein the hollow body has a length corresponding to a desired depth of implantation, and wherein said outer ring structure includes a first plurality of openings forming an external lattice structure.
A prosthetic implant, comprising:
- an interface portion operative to interface with an other structure;
- and
- a stem coupled to said interface portion, wherein the stem is structured for implantation to a desired depth into a bone tissue, and wherein the stem includes:
- a body having a length corresponding to a desired depth of implantation;
- and
- a plurality of protrusions extending outwardly from said body and spaced apart from each other along the length of said body, wherein said protrusions are integrally formed with said body and are operative to engage the bone tissue.
A method of forming a prosthetic implant, comprising:
- freeform fabricating a ceramic mold having an integral core and integral shell, said ceramic mold structured to yield a cast prosthetic implant;
- sintering the ceramic mold;
- supplying a molten alloy to the sintered mold;
- and
- removing the ceramic mold to yield the cast prosthetic implant.
A method of forming a prosthetic implant, comprising:
- electronically defining a ceramic mold having an integral core and integral shell for casting a prosthetic implant;
- freeform fabricating the ceramic mold using the electronic definition;
- supplying a molten alloy to the ceramic mold;
- solidifying the molten alloy;
- and
- leaching the ceramic mold to yield a cast prosthetic implant.
