30 results about "Tibial nerve" patented technology

The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.

Treatment of indications using electrical stimulation

In one embodiment, a method includes implanting an implant entirely under the subject's skin. The implant includes a passive electrical conductor of sufficient length to extend from subcutaneous tissue located below one of a surface cathodic electrode and a surface anodic electrode to the tibial nerve. The surface electrodes are positioned in spaced relationship on the subject's skin, with one of the electrodes positioned over the pick-up end of the electrical conductor such that the portion of the current is transmitted through the conductor to the tibial nerve, and such that the current flows through the tibial nerve and returns to the other of the surface cathodic electrode and the surface anodic electrode. An electrical current is applied between the surface cathodic electrode and the surface anodic electrode to cause the portion of the electrical current to flow through the implant to stimulate the tibial nerve.

An improved knee joint prosthesis located between a thighbone and a tibia to couple with a femur implanted component to allow a patient to resume normal movement and exercise. The knee joint prosthesis adopts a separate design, and includes a tibial insert which has a moving aperture to hold a bracing member coupled with the femur implanted member and a tibial baseplate which has a retaining member. The bracing member and the retaining member are swivelable in the moving aperture, and the bracing member is made from wearing resistant material, so that sliding and wearing that might otherwise occur to the tibial insert may be prevented. Therefore the life span of the posterior stabilized knee joint prosthesis increases.
