Patent number: 9283093Abstract: An adjustable socket system, method, and kit for use with prosthetic devices or orthotic, orthopedic, or exoskeletal support devices that includes a paddle and a compressing device coupled to the paddle. The paddle is chosen from a plurality of paddles of different shapes in such a way that the paddle inner surface is substantially coextensive with a soft tissue area overlying skeletal structures. The compressing device presses the paddle against the soft tissue area in order to minimize the motion of the paddle relative to the underlying skeletal structures without causing discomfort to the user or compressing areas not in contact with the paddle, allowing compressed tissue to flow into uncompressed areas. The system, method, and kit can include an external tool, sensors, actuators, and controllers, to assist fitting and for adjustment after fitting. A stabilizer can be added to resist the bending force on the paddle.Type: GrantFiled: March 12, 2013Date of Patent: March 15, 2016Inventor: Randall D. Alley
