Abstract

The foam insert is for use in manufacturing a prosthetic socket. The foam insert includes an elongated foam body extending from an open end to a closed end, and configured to be positioned within a rigid canister. The elongated foam body includes a contoured exterior surface configured to transfer pressure through to an interior surface thereof to produce consistent surface contact with a residual limb having casting material thereon. The interior surface of the elongated foam body includes a smooth interior surface configured to interface with the residual limb.

Claims

exact text as granted — not AI-modified
That which is claimed is: 
     
         1 . A foam insert for use in manufacturing a prosthetic socket, the foam insert comprising:
 an elongated foam body extending from an open end to a closed end, and configured to be positioned within a rigid canister;   the elongated foam body including a contoured exterior surface configured to transfer pressure through to an interior surface thereof to produce consistent surface contact with a residual limb having casting material thereon; and   the interior surface of the elongated foam body including a smooth interior surface configured to interface with the residual limb.   
     
     
         2 . The foam insert according to  claim 1 , wherein the contoured exterior surface of the foam insert comprises a waffle pattern defining a contoured pattern of squares. 
     
     
         3 . The foam insert according to  claim 1 , wherein the contoured exterior surface of the foam insert comprises a matrix of peaks and valleys. 
     
     
         4 . The foam insert according to  claim 1 , wherein the elongated foam body comprises a compressible foam material including a urethane flexible foam. 
     
     
         5 . The foam insert according to  claim 1 , wherein the elongated foam body comprises a compressible foam material including a silicone flexible foam. 
     
     
         6 . A foam insert for use in manufacturing a prosthetic socket, the foam insert comprising:
 an elongated foam body extending from an open end to a closed end, and configured to be positioned within a rigid canister;   the elongated foam body including a contoured exterior surface configured to transfer pressure through to an interior surface thereof to produce consistent surface contact with a residual limb having casting material thereon.   
     
     
         7 . The foam insert according to  claim 6 , wherein the contoured exterior surface of the foam insert comprises a waffle pattern defining a contoured pattern of squares. 
     
     
         8 . The foam insert according to  claim 7 , wherein the interior surface of the elongated foam body comprises a smooth interior surface configured to interface with the residual limb. 
     
     
         9 . The foam insert according to  claim 6 , wherein the contoured exterior surface of the foam insert comprises a matrix of peaks and valleys. 
     
     
         10 . The foam insert according to  claim 6 , wherein the elongated foam body comprises a compressible foam material including a urethane flexible foam. 
     
     
         11 . The foam insert according to  claim 6 , wherein the elongated foam body comprises a compressible foam material including a silicone flexible foam. 
     
     
         12 . A method of making a foam insert for use in manufacturing a prosthetic socket, the method comprising:
 providing an elongated foam body extending from an open end to a closed end, and configured to be positioned within a rigid canister; and   forming a contoured exterior surface on the elongated foam body to transfer pressure through to an interior surface thereof to produce consistent surface contact with a residual limb having casting material thereon.   
     
     
         13 . The method according to  claim 12 , wherein the contoured exterior surface of the foam insert comprises a waffle pattern defining a contoured pattern of squares. 
     
     
         14 . The method according to  claim 13 , wherein the interior surface of the elongated foam body comprises a smooth interior surface configured to interface with the residual limb. 
     
     
         15 . The method according to  claim 12 , wherein the contoured exterior surface of the foam insert comprises a matrix of peaks and valleys. 
     
     
         16 . The method according to  claim 12 , wherein the elongated foam body comprises a compressible foam material including a urethane flexible foam. 
     
     
         17 . The method according to  claim 12 , wherein the elongated foam body comprises a compressible foam material including a silicone flexible foam.
