Publication number: 20080004715Abstract: A method and kit for forming a definitive prosthetic socket directly on a residuum without the use of a water hardenable material. A chamber surrounding a web of braided fibers is created on the residuum via the use of inner and outer protective sheaths. A hardenable or curable material for forming the prosthetic socket is injected into the chamber around the web. Pressure is applied around the chamber to form the definitive prosthetic socket.Type: ApplicationFiled: June 28, 2007Publication date: January 3, 2008Inventor: Sigurdur Asgeirsson

Patent number: 7311866Abstract: Disclosed is a method for producing a three-dimensional composite structure and a method for producing the mold for the three-dimensional composite structure. The mold is formed of at least one rigid die member and a second thermoplastic die member. The second thermoplastic die member is formed by coupling a rubber flexible pattern to a surface of the first die member. Vacuum or pressure is applied to a heated thermoplastic sheet to cause the heated thermoplastic sheet to deform about the flexible pattern, thereby forming the second die. Strips of reinforced polymer thermoset pre-preg material are then positioned within the cavities formed by the flexible pattern and are allowed to cure. Optionally, heat, pressure, and vacuum may be applied to the mold construction to facilitate the curing of the thermoset materials.Type: GrantFiled: June 25, 2003Date of Patent: December 25, 2007Assignee: EBI, L.P.Inventors: Jeffrey B. Stearns, Juan B. Paez

Patent number: 7240414Abstract: A method of sizing, resizing or reshaping the interior of a prosthetic device includes placing a lightweight moldable or shape assuming, pliable material that adheres and hardens on the interior sides of a socket of a prosthetic device. An end of a residual limb is placed into the socket causing the moldable material to conform to the shape of the residual limb. The limb is maintained in position for a few minutes in the socket until the moldable material has sufficiently hardened. After hardening, the molded material is dressed down, sanded or feathered to remove any burrs or sharp edges. Low spots or holes may be filled in with more moldable material and the fitting process repeated.Type: GrantFiled: February 6, 2004Date of Patent: July 10, 2007Inventor: Matthew T. Taylor, Sr.

Patent number: 7220376Abstract: A negative impression of an anatomical portion of a person is captured by forcing the anatomical portion into impression foam to collapse the impression foam into the negative impression. The impression foam has a crush characteristic of approximately constant resistance force over a relatively wide predetermined range of collapse distances. The negative impression is obtained by collapsing the impression foam within the range of constant-force collapse distances, thereby creating the negative impression under conditions which reflect an equally-loaded anatomical portion. A cushion support contour created from the equally-loaded negative impression is beneficial in more appropriately supporting the anatomical portion. The present invention is particularly useful in fabricating wheelchair seat cushions.Type: GrantFiled: July 28, 2003Date of Patent: May 22, 2007Assignee: Aspen Seating, LLCInventors: Thomas R. Hetzel, Joseph S. Bieganek

Patent number: 7097799Abstract: A method of forming prosthetic sockets is provided that first creates a negative mold of the patient's residual limb while it is disposed in a positive flexion position. The mold is then removed and shaped to permit the desired range of flexion when the mold is repositioned on the residual limb. A second cast is made of the residual limb that incorporates the mold. A positive model of the residual limb is then formed, from which test or definitive sockets may be formed. The present method further lends itself to the formation of sockets using a cast-in-place methodology while the limb is disposed in a positive flexion position.Type: GrantFiled: February 23, 2004Date of Patent: August 29, 2006Inventor: Russell F. Burton

Patent number: RE40487Abstract: A method for forming the outer surface of a breast prosthesis is disclosed. A digital, three-dimensional image is formed of a patient's breast using a computerized scanner. A computer-controlled milling machine utilizes the image to form a solid model of the breast. A sheet of flexible, moldable material having a uniform, precise thickness is then vacuum-formed over the breast model. A hard, two-piece mold is cast from the flexible sheet. A soft, curable material is then either poured or injected between the two pieces of the mold to form the breast prosthesis outer surface. The breast prosthesis outer surface is then turned inside out to form a shape that is a mirror image of the patient's breast.Type: GrantFiled: July 11, 2002Date of Patent: September 9, 2008Assignee: Board of Trustees of the University of ArkansasInventor: L.
