  • Publication number: 20150066156
    Abstract: Local swing leg control was developed that takes advantage of segment interactions to achieve robust leg placement under large disturbances while generating trajectories and joint torque patterns similar to those observed in human walking and running. The results suggest the identified control as a powerful alternative to existing swing leg controls in humanoid and rehabilitation robotics. Alternatively, a detailed neuromuscular model of the human swing leg was developed to embody the control with local muscle reflexes. The resulting reflex control robustly places the swing leg into a wide range of landing points observed in human walking and running, and it generates similar patterns of joint torques and muscle activations. The results suggest an alternative to existing swing leg controls in humanoid and rehabilitation robotics which does not require central processing.

In another aspect, the invention provides methods and apparatus for outputting positive power from a prosthesis or orthosis, facilitating high-performance artificial limbs. In one embodiment of the invention, the positive power is transferred from a functioning muscle to the prosthesis or orthosis, which mimics or assists a non-functioning or impaired muscle. In another embodiment of the invention, the positive power comes from an on-board power source in the prosthesis or orthosis.

  • Publication number: 20140081422
    Abstract: Provided herein are devices and methods for connecting a transcutaneous external prosthetic device to a bone, such as a bone of an amputee. The device is a two-piece transcutaneous implant device to provide reversible connection for ease of implantation, reliability, and relatively easy access for removal, while maximizing tissue ingrowth to reduce risk of infection and attendant adverse outcomes. The devices provided herein comprise a prosthetic interface and a bone anchor. A through-hole that traverses a longitudinal length of the prosthetic interface and at least a longitudinal portion of the bone anchor receives a fastener to reversibly connect the prosthetic interface to the bone anchor implanted in bone. A connector may connect to a failsafe element which, in turn, connects to an external prosthetic device.

  • Patent number: 8641778
    Abstract: A method and apparatus for reducing the incident of infection proximate to an exit site where a prosthesis fastener, e.g., a bone screw, percutaneously penetrates a patient's skin/soft tissue. Infection reduction is achieved in accordance with the invention by growing a tissue integrating seal around the fastener proximate to the exit site.

  • Patent number: 8632607
    Abstract: Permanent magnets or electromagnets or a combination of such magnets are provided to retain a prosthetic device on an extremity or limb, such as an amputated arm. The prosthesis utilizes the opposing forces, which are developed by virtue of like magnetic poles being in proximity to each other, to urge the prosthesis to remain attached to the extremity. The prosthesis is prevented from rotation by virtue of a centering force that is provided by an attachment magnet in the prosthesis being placed between two implanted magnets. A removable mounting ring is placed over the prosthesis to maintain it on the extremity.

  • Patent number: 8598815
    Abstract: Torsional loads can impart painful and potentially injurious shear stresses upon residual limb soft tissues in lower limb amputees. To protect the soft tissues, a controllable transverse rotation adapter (TRA) has been developed that permits rotation of the prosthetic socket relative to the prosthetic foot, relieving some of the rotational loads experienced by the residual limb, and controlling either the stiffness resisting the transverse rotational torque, or the torque. This TRA uses series elastic actuator (SEA) technology and includes a prime mover, a speed reduction device, and a torsion spring mounted in series. By measuring a displacement of the spring (e.g., using a strain gauge), motor current, and the motor shaft position, the load torque and position can be used to calculate actual stiffness or applied torque. The motor position is then adjusted relative to the load, to control the effective stiffness or torque.

  • Publication number: 20130253664
    Abstract: An antimicrobial containment cap is provided for use in a bone anchored prosthesis mounting system of the type having an externally protruding fixator pin carried by implanted bone anchored mounting post, wherein the fixator pin accommodates removable attachment to an exoskeletal prosthesis such as a prosthetic limb or the like for an amputee. The containment cap, when mounted onto the fixator pin, is interposed between the prosthesis and soft tissue covering the end or stump of an amputated residual limb or the like. The containment cap carries and supports a selected antimicrobial or antibacterial agent in substantial contact with the soft stump tissue in a position closely overlying and substantially circumscribing the tissue interface with the externally protruding fixator pin to safeguard against infection. The containment cap is adapted for quick and easy periodic removal for cleaning and/or replenishment of the antimicrobial agent.

  • Patent number: 8491667
    Abstract: A modular prosthesis system that can be inexpensively manufactured using modern technology and advanced polymer materials. The modular prosthesis system will be immediately fit on the residual limb and aligned for optimal gait without specialized tools or labs, alleviating the many steps involved with conventional labor-intensive and costly prosthesis construction. The modular prosthesis system also accommodates the changing in size and shape of the limb, eliminating the need for multiple prostheses and adjustments to an existing prosthesis during the lifetime of an amputee.

  • Patent number: 8435308
    Abstract: A locking device for a prosthesis comprising a locking mechanism that may be disengaged from the locking pin using a single hand, and that remains in the open position until the pin is removed. The locking mechanism of the present invention thus provides a secure connection that may be more easily removed than current devices. The current invention comprises a self-holding release mechanism that makes it possible to use both hands for pulling the amputation stump out of the prosthetic sleeve. The release mechanism is held in an open position by an interior locking mechanism. When the locking pin has come out of the locking mechanism, the inner locking mechanism will let the release device return and the lock will reset, and again be ready for use when the locking pin is inserted once more.

  • Patent number: 8414658
    Abstract: An upper extremity prosthetic device is provided that comprises three main components, namely, an arm cuff, a forearm section and a distal connector. The arm cuff is adjustable to accommodate lower arms of different sizes. The forearm section may be constructed in certain limited sizes to accommodate different sized forearm residual limbs. The distal connector is designed to connect to any of the forearm section configurations, and the distal connector enables any terminal device to be attached to the connector. The components may be mixed and matched in various combinations to fit the physical dimensions of virtually any amputee. The interchangeable parts will accommodate a wide range of residual limb geometries, overall sizes and lengths. Embodiments of the present invention minimize the need for time and resource-intensive customized fitting and create an affordable, relatively low-cost prosthetic interface.
