Patent number: 8696764Abstract: The present invention relates to an improved system for use in rehabilitation and/or physical therapy for the treatment of injury or disease to the lower limbs or extremities. The system can enable an amputee to proceed over any inclined or declined surface without overbalancing. The system is mechanically passive in that it does not utilize motors, force generating devices, batteries, or powered sources that may add undesirable weight or mass and that may require recharging. In particular the system is self-adapting to adjust the torque moment depending upon the motion, the extent of inclination, and the surface topography. An additional advantage of the improvement is that the system can be light and may also be simple to manufacture.Type: GrantFiled: January 20, 2012Date of Patent: April 15, 2014Assignee: Northwestern UniversityInventors: Andrew H. Hansen, Eric A. Nickel

Patent number: 8690962Abstract: This invention provides new above knee (AK) and below the knee (BK) prosthetic sockets and implements specific manufacturing processes for the production of prosthetic sockets through the automated, computer controlled bi-axial and tri-axial braiding of sockets, over a mold or mandrel made of carved foam, plaster material or wax that is a replica of the patient's truncated limb, and is created by a Computer Aided Design (CAD) file controlling a Numerically Controlled (CNC) machine tool. This method of manufacture using aerospace fibers such as graphite or Kevlar, and high performance resins, is used to create a socket which is stronger and lighter weight than conventionally manufactured sockets. Braiding also allows incorporation of woven cloth, tapes and other reinforcements into the braiding process for added strength at selected areas. The method dramatically decreases the production time and cost of the prosthetic relative to conventional methods.Type: GrantFiled: December 15, 2011Date of Patent: April 8, 2014Assignee: Mentis Sciences, Inc.Inventors: John J. Dignam, Bradley J. Mate, Christopher S. Anderson, Patrick P. McDermott
