Implanted medical system including a self-powered sensing system
First Claim
1. An implantable medical system for use in the control of the operation of a part of a body comprising:
- control unit means for mounting in one location of a body;
control circuit means in said control unit means for controlling the operation of the control unit means;
battery means in said control unit means for supplying electrical energy to said control unit means and said control circuit means;
flexible lead means for mounting in said body and being connected to said control unit means and extending from said control unit means to another location inside said body;
said flexible lead means comprising a continuous flexible hollow tube having an outer and an inner surface;
stimulation electrode means mounted on said flexible lead means and being located in said another location for receiving electrical energy from said control unit means through said flexible lead means and applying electrical energy to said body at said another location;
self-contained, self-powered, flexible, electrical signal generating means mounted in a portion of said flexible lead means in spaced relationship to said stimulation electrode means for self-generation of electrical control signals solely by mechanical movement induced solely by flexible movement of said flexible lead means in said another location caused by action of and conditions in the body and without any electrical connection to and supply of electrical energy from any other source;
a fixed support secured to said inner surface;
said self-contained, self-powered, flexible, electrical signal generating means mounted for cantilever action on said fixed support; and
electrical control signal transmitting means, connected to said self-contained, self-powered, flexible, electrical signal generating means and said control circuit means, to transmit the generated electrical control signals to said control circuit means.

Abstract
Self-contained, self-powered, flexible electrical control signal generating means are located in the right ventricle of a heart and generate electrical control signals solely by mechanical movements caused by actions of and conditions in the heart without any electrical connection to and supply of electrical energy from any other power source which electric control signals are transmitted to a control circuit system of an implanted control unit which control unit transmits an electrical signal to a stimulation electrode implanted in tissue at the apex of the right ventricle of the heart which stimulation electrode uses the electrical signal to stimulate the heart.
