A method for construction of Nitinol antenna for implantable medical devices

Abstract

A methods for construction of inductively coupled implants within human or animal bodies are disclosed. An internal coil assembly to be used with the implant and receives both power and data from the external transmitting coil. The internal coil assembly design and choice of specific construction materials significantly reduces size while improving biocompatibility and ease of implantation. Nickel Titanium shape-memory alloy (Nitinol) is used with other materials to form a functional, biocompatible antenna. The geometry of the internal receiving coil assembly and distance are chosen to reduce the influence of noise and increase efficiency.
