Double-wall prosthetic limb assembly

A double-wall prosthetic limb socket assembly comprising:

• a first inner-wall socket adapted to receive a patient's residual limb;
• a second outer-wall socket seating the first inner-wall socket therein, the second outer-wall socket including,
• a distal, circular base-plate;
• and
• a molded circumferential wall bonded to and extending proximally from the distal, circular base-plate;
• a first one of a female and a male component of a mechanical lock seated between the first inner-wall socket and the second outer-wall socket over a proximal end of the circular base-plate;
• and
• a complimentary component of the first component of the mechanical lock extending from the first inner-wall socket and mating with the first component of the mechanical lock thus providing a mechanical lock between the first inner-wall socket and second outer-wall socket;
• the circular base-plate including a vacuum port extending an outer surface of the base-plate in fluid communication with a vacuum channel extending through the circular base-plate and out through an outlet hole in a proximal side of the circular base-plate;
• whereby, when the vacuum port is coupled to a vacuum pump, the vacuum will help to draw the first inner-wall socket into the second outer-wall socket.

• a distal, circular base-plate;
• and
• a molded circumferential wall bonded to and extending proximally from the distal, circular base-plate;
• the circular base-plate including one or more indentations extending into a circumferential outer side of the circular base-plate into which material of the molded circumferential wall is received, thus facilitating a mechanical bond between the circular base-plate and the molded circumferential wall;
• the circular base-plate also including a vacuum port extending an outer surface of the base-plate in fluid communication with a vacuum channel extending through the circular base-plate and out through an outlet hole in a proximal side of the circular base-plate;
• whereby, when the vacuum port is coupled to a vacuum pump, the vacuum will help to draw the first inner-wall socket into the second outer-wall socket.

A method for fabricating a double-wall prosthetic limb socket assembly comprising the steps of:

• fabricating a first inner-wall socket that is adapted to receive a patient's residual limb;
• installing a positive mold end-block over a distal end of the first inner-wall socket, the positive mold end-block having outer dimensions approximating outer dimensions of components to be installed between the distal end of the inner-wall socket and an outer-wall socket;
• installing a distal-end attachment plate component of the outer-wall socket over a distal end of the positive mold end-block, the distal-end attachment plate component having one or more indentations extending into a circumferential outer side of the distal-end attachment plate into which material of a molded circumferential wall of the second outer-wall socket will be received;
• and
• molding the circumferential wall of the second outer-wall socket over the first inner-wall socket, over lateral sides of the positive mold end-block and into the one or more indentations extending into the circumferential outer side of the distal end attachment plate.

• the circular base-plate also including a vacuum port extending an outer surface of the base-plate in fluid communication with a vacuum channel extending through the circular base-plate and out through an outlet hole in a proximal side of the circular base-plate;
