Method and kit for making prosthetic socket

1. A method for forming a prosthetic socket directly on a residuum, the method comprising the steps of:

placing an inner protective sheath over a residuum;

placing a web over the inner protective sheath;

placing an outer protective sheath over the web;

forming a first seal at a proximal end between the inner and outer protective sheaths;

forming a second seal at a distal end between the inner and outer protective sheaths;

wherein an enclosed zone is formed around the web between the inner and outer protective sheaths; and

injecting material into the enclosed zone to form the prosthetic socket.

2. The method of forming a prosthetic socket according to claim 1 , further comprising the step of:

placing a liner on the residuum prior to placing the inner protective sheath over a residuum.

3. The method of forming a prosthetic socket according to claim 2 , further comprising the step of:

placing a prosthesis coupler element on the web prior to placing the web over the inner protective sheath.

4. The method of forming a prosthetic socket according to claim 3 , further comprising the step of:

tightening the prosthesis coupler element to the liner prior to placing the outer protective sheath over the web.

5. The method of forming a prosthetic socket according to claim 4 , further comprising the step of:

placing an injection fitting on the prosthesis coupler element prior to injecting material into the enclosed zone.

6. The method of forming a prosthetic socket according to claim 1 , further comprising the step of:

applying pressure around the outer protective sheath, after injecting material into the enclosed zone.

7. The method of forming a prosthetic socket according to claim 1 , further comprising the step of:

placing a breather between the inner and outer protective sheaths, prior to creating the first seal.

8. The method of forming a prosthetic socket according to claim 1 , further comprising the step of:

removing the outer protective sheath from around the formed prosthetic socket;

removing the prosthetic socket from around the inner protective sheath; and

trimming excess material from the prosthetic socket.

9. A kit for forming a prosthetic socket directly on a residuum, the kit comprising:

an inner protective sheath;

an outer protective sheath;

a web having a plurality of fibers capable of receiving a hardenable material;

and a hardenable material for impregnating the plurality of fibers of the web.

10. The kit for forming a prosthetic socket of claim 9 , further comprising:

a prosthesis coupler element;

a breather having an air permeable structure; and

an injection fitting for permitting passage of the hardenable material therethrough.

11. The kit for forming a prosthetic socket of claim 9 , further comprising:

a silicone liner that is air and moisture impervious; and

protective wrapping film arranged for wrapping about the liner.

12. A kit for forming a prosthetic socket directly on a residuum, the kit comprising:

a generally tubular web;

an inner protective sheath;

an outer protective sheath; and

a hardenable material for impregnating the web.

13. A kit for forming a prosthetic socket according to claim 12 , wherein the hardenable material is a two component, curable polyurethane resin.

14. A kit for forming a prosthetic socket according to claim 12 , wherein the hardenable material is Plaster-of-Paris.

15. A kit for forming a prosthetic socket according to claim 12 , wherein the web comprises:

at least one layer of braided fibers.

16. A kit for forming a prosthetic socket according to claim 15 , wherein the braided fibers are glass fibers or carbon fibers.

17. A kit for forming a prosthetic socket according to claim 15 , wherein the braided fibers are oriented relative to each other at an angle of between 0 degrees and 90 degrees.

18. A kit for forming a prosthetic socket according to claim 15 , wherein the web further comprises:

a prosthesis coupler element attached to a distal end of the web.

19. A kit for forming a prosthetic socket according to claim 12 , wherein the web comprises a first layer of braided fibers oriented in a first direction and a second layer of braided fibers oriented in a second, different direction.

20. A kit for forming a prosthetic socket according to claim 12 , further comprising:

an injection system for impregnating the hardenable material into the web.
