Patent application number | Description | Published |
20120016493 | Passive ankle-foot prosthesis and orthosis capable of automatic adaptation to sloped walking surfaces and method of use - 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. | 01-19-2012 |
20120116540 | Prosthetic foot and method of making - A prosthetic foot is made by machining or molding a prosthetic foot profile to have a plurality of slots in and along the length of the forefoot region of the foot shape to achieve the appropriate roll-over shape during walking, and slotting the heel region of the machined foot shape to provide shock absorption in early stance phase of walking. | 05-10-2012 |
20130006386 | Further improvements to ankle-foot prosthesis and orthosis capable of automatic adaptation to sloped walking surfaces and methods of use - 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.

20130096694 | VACUUM PUMP SYSTEMS FOR PROSTHETIC LIMBS AND METHODS OF USING THE SAME - Pump systems for use in suspension of a prosthetic device from a residual limb and methods of suspending a prosthetic device from a residual limb are disclosed. The pump systems include a mechanically activated pump having a first compression member coupled to a second compression member, a compressible bladder disposed between the first and second compression members, and coupling elements that engage and couple together the first and second compression members. The mechanically activated pump may be connected with an electrically activated pump within a fluid circuit of a hybrid pump system to provide vacuum engagement between a prosthetic device and a residual limb. | 04-18-2013 |
20140074255 | ARTIFICIAL ANKLE, ARTIFICIAL FOOT AND ARTIFICIAL LEG - The present invention relates in the field of orthopedics to an artificial ankle which imitates the natural human gait in a proper way, thereby enabling its user to walk not only in a plane environment but also uphill and downhill without any unpleasant effects. The present invention further relates to an artificial foot and an artificial leg containing said artificial ankle. | 03-13-2014 |
20140087920 | Foldable Parallel Bar Apparatus - A foldable parallel bar apparatus includes generally U-shaped first and second end frames and a set of handrails connected to and extending between the first and second end frames, wherein the handrails are foldable so as to move the first and second end frames closer to one another thereby compacting the apparatus. When multiple modules of the end frames are connected, they provide an uninterrupted path between the handrails. An alternative embodiment provides base platforms that are foldable relative to each other and handrails that are vertically and horizontally adjustable. | 03-27-2014 |
20140088730 | Ankle-Foot Prosthesis for Automatic Adaptation to Sloped Walking Surfaces - An ankle-foot prosthesis includes a foot plate, an ankle frame attached to the foot plate, a yoke pivotally connected to the ankle frame and including a member for attaching to a leg, a damper having a first end connected to the yoke and a second end connected to the ankle frame, and a control mechanism for switching the damper between low and high settings. | 03-27-2014 |
