Abstract

A prosthesis includes an outer capsule that is made of biosorbable material. An inner capsule is encapsulated by the outer capsule. A layer of fluid is interposed between the outer capsule and the inner capsule. In one implementation, the inner capsule surrounds autologous fluids or saline. Also, the layer of fluid interposed between the outer capsule and the inner capsule may comprise autologous fluids or saline.

Claims

1. A prosthesis, comprising:

an outer capsule made of biosorbable material;

an inner capsule encapsulated by the outer capsule, wherein the inner capsule surrounds a member made of autologous fluids; and

a layer of fluid interposed between the outer capsule and the inner capsule.

2. The prosthesis of claim 1, wherein the inner capsule is partially resorbable.

3. The prosthesis of claim 1, wherein the autologous fluids are autologous blood products.

4. The prosthesis of claim 1, wherein the layer of fluid interposed between the outer capsule and the inner capsule comprises autologous fluids.

5. The prosthesis of claim 4, wherein the autologous fluids are autologous blood products.

6. A prosthesis for insertion into a surgically formed cavity, comprising:

an inner capsule containing a fluid;

an outer capsule made of biosorbable material, the outer capsule encapsulating the inner capsule; and

a fluid layer that separates the inner capsule and the outer capsule, wherein the fluid layer comprises autologous fluids.

7. The prosthesis of claim 6, wherein the inner capsule is partially resorbable.

8. The prosthesis of claim 6, wherein the fluid contained by the inner capsule is autologous fluids.

9. The prosthesis of claim 6, wherein the fluid contained by the inner capsule is saline.

10. The prosthesis of claim 8, wherein the autologous fluids are autologous blood products.

11. A prosthesis for insertion into a surgically formed cavity, comprising:

an inner capsule containing a fluid;

an outer capsule made of biosorbable material, the outer capsule encapsulating the inner capsule; and

a fluid layer that separates the inner capsule and the outer capsule, wherein the fluid layer comprises autologous blood products.
