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.

Abstract: A method is provided of producing a moulding having a configuration corresponding to the surface configuration of a model. The method comprises the steps of bringing a gas-tight evacuatable container having at least one flexible wall portion in a position relative the configuration of the model such that the wall portion can be deformed to the contours of the model without cracking or creasing. A quantity of granular material is then poured into the container to deform the flexible wall portion to the shape of the model by pressure, whereafter at least a partial vacuum is created in the container to cause the granules to form a solid, persistent mass conforming to the shape of the model. The model is then removed while maintaining the condition of at least partial vacuum in the container.
