Abstract
A transcutaneous prosthesis is disclosed comprising a first component (1) shaped for implantation into a bone (2), a second component (4) intended for location between the bone (2) and the skin, and a third component (5) intended for location exterior to the skin surface, having a low surface energy which deters bacterial adhesion. The second component (4) may carry an adhesion-promoting protein.
Claims11
A transcutaneous prosthesis which comprises a first component shaped for implantation into a bone, a second component intended for location between the bone and the skin, the second component having a surface treatment for stimulation of fibroblastic cell proliferation and attachment of epithelial cells and a third component intended for location exterior to the skin surface having a low surface energy which deters bacterial adhesion.
A prosthesis according to any one of the preceding claims wherein the second component has a micro-pitted surface.
A prosthesis according to any one of the preceding claims wherein the surface of the second component carries a fibronectin or laminin coating.
A prosthesis according to any one of the preceding claims wherein the second component extends outwardly from the first and third components.
A prosthesis according to any one of the preceding claims where the third component carries a coating comprising a fluoro- or silicone polymer.
A prosthesis according to any one of the preceding claims wherein the third component carries a coating comprising diamond like carbon.
A prosthesis according to any one of the preceding claims wherein the third component includes a frangible or detachable linkage which permits an external component to detach in the event that an unusually high load is applied to the prosthesis.
A prosthesis according to any one of the preceding claims in which the third component is connected to an artificial limb or digit.
