Abstract: The attachment plate for a prosthetic socket is fabricated into the distal end of a prosthetic socket. The attachment plate comprises a body with a peripheral seal, a valve, an air tunnel, and an exhaust port. When fastened in the distal end of a prosthetic socket, the peripheral seal creates a secure seal to the inner wall of the prosthetic socket and the exhaust port remains exposed to atmosphere. The valve is open to the cavity of the prosthetic socket for air to be removed to secure a prosthetic via vacuum or suction. Air from the cavity moves through the valve, through an air tunnel machined into the cylindrical body, and is expelled out of the exhaust port.

Abstract: The Prosthetic Vacuum Pump is a manually-operated device, that is affixed to or integral with a prosthetic socket. The manual operation allows a wearer to increase the vacuum in the socket cavity if there is any noticeable decrease at any time. The Prosthetic Vacuum Pump includes a removable pump mechanism that allows a user to customize the level of vacuum drawn by the Prosthetic Vacuum Pump. The intake valve of the Prosthetic Vacuum Pump is in direct connection with the cavity of a prosthetic socket. By eliminating vacuum lines, the vacuum pump creates an immediate vacuum in the cavity. The result is an immediate suspension when the prosthetic limb is put on without the need to walk or wait for the battery to draw a sufficient vacuum. The compact construction and optional depress-lock is easily hidden beneath clothing.

Abstract: A liner interface and method of making the liner interface comprising attaching non-compressible deformable electrically conductive receptors to an inner surface of a fabric layer, placing the fabric layer into a female part of a molding machine, axially deforming the deformable receptors from their initial thickness with a male part of the molding machine, injecting a molten gel elastomer into the molding machine to completely surround and adhere to the receptors and inner surface of the tubular fabric layer, allowing the molten gel to cure, and removing the male part from the molding machine and allowing the axially deformed receptors to axially expand beyond the inner surface of the cured liner interface.

Abstract: The following invention is a device for measuring the force applied by the residual limb of an amputee to the distal region of a socket. The device has an upper surface with a “force sensor measuring region” that maintains a central location on the upper surface of the DFMD. The DFMD is affixed to the inside surface of the distal most area of the socket and maintains a permanent location of the “force sensor measuring region” of the device. Regardless of physical characteristics or changes to the socket, liner, socks, proper or improper placement of the limb into the socket, the consistent location of the “force sensor measuring region” on the DFMD provides congruent force data as it relates to the force applied by the socket to the distal area of the residual limb. The data collected by the DFMD is processed and modified by a software algorithm into meaningful data for the user and/or medical professional.

Abstract: A gel liner made by starting initially with a one-piece knitted tubular sock-shaped fabric having a closed distal end section of gel impermeable knitted fabric and an open proximal end section of gel impermeable knitted fabric and being a gel permeable loosely knitted fabric. Molding the liner to have a gel cushion layer on its interior surface with the gel passing through and partially embedding the yarns of the proximal fabric section with the outermost portions of the yarns free of gel to form at least one annular seal whereby the proximal end section forming a seal not inhibited in deformation and/or elongation by the fabric when the liner is worn thereby reducing or eliminating any twisting or discomfort of the liner during ambulation caused by the annular seal.

Abstract: An insert interface adapted to fit within a prosthesis between a convex-shaped distal end of a prosthetic liner and an interior distal end of a prosthetic socket for collecting data measurement of the fit of a residual limb of an amputee within the prosthesis comprising an insert comprising a resilient pad of elastomeric material having an upper surface and a lower surface with a concave shaped upper surface adapted to provide a contiguous surface with an interior surface of a prosthetic socket when inserted therein and provide a cushion for a distal end of a residual limb when worn by an amputee, and a lower surface having a shape complementally configured to a distal interior surface of a prosthetic socket when inserted therein, and at least one force sensor mounted centrally within said pad in proximity to the upper surface of the pad for sensing forces against the pad created by a downward movement of a residual limb of an amputee when wearing the socket and for electronically wirelessly transmitting data

Abstract: A liner interface and method of making comprising non-compressible deformable electrically conductive neural receptors having electrically conductive elements extending therefrom, formed by attaching each receptor and the conductive elements to an inner surface of a fabric layer, placing the fabric layer into a first part of a molding machine having a predetermined shape, moving a second part of the molding machine having a shape complemental to the first predetermined shape toward said fabric layer to either abut or axially deform the deformable receptors and define a space therebetween, injecting a molten gel elastomer into the space to surround and adhere to the receptors, conductive elements and fabric layer, allowing the molten gel to cure to form a gel inner surface, and removing the second part from the molding machine and allowing the receptors to either axially expand beyond or remain even with the inner surface of the cured liner interface.

Abstract: A gel liner made by starting initially with a one-piece knitted tubular sock-shaped fabric having a closed distal end section of gel impermeable knitted fabric, an open proximal end section of gel impermeable knitted fabric and at least one intermediate section being a gel permeable loosely knitted fabric.
