International Classification:

A61N 1/36
A61B 5/02

US Classification:

607 33, 600508

Abstract:

Aspects according to the present invention provide a method and implant suitable for implantation inside a human body that includes a power consuming means responsive to a physiological requirement of the human body, a power source and a power storage device. The power source comprises a sheathed piezoelectric assembly that is configured to generate an electrical current when flexed by the tissue of the body and communicate the generated current to the power storage device, which is electrically coupled to the power source and to the power consuming means.
