  • Method of manufacturing a prosthesis cuff to receive an amputation stump
    Patent number: 4696780
    Abstract: In a method of manufacturing a prosthesis cuff to receive an amputation stump, particularly for a lower-leg prosthesis, a positive cast of the stump is positioned in an expanded and heat shrinkable rough cuff of a plastics material, whereupon the rough cuff is caused by heating and vacuum-forming to adjust to the surface contour of the stump. The positive cast is subsequently removed. A connecting element for the prosthesis is provided on the rough cuff, for example having formation embedded in the plastics material.
