摘要： 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.

摘要： A pacemaker terminal for connecting an electrode lead having a proximal end includes a first section fixed to the pacemaker and a second section moveably engaged with the first section. A spring element is interposed between the first and second sections to exert a force to displace the moveable section from the fixed section. Both sections have transverse holes which, upon application of squeezing pressure to the terminal to overcome the spring action, become aligned so as to allow insertion of the proximal end of the electrode lead. Thereafter, upon release of the pressure, the spring element displaces the sections so as to capture the electrode lead securely in the holes. The holes may be provided with an internal thread, such as an asymmetrial sawtooth pattern, to aid in holding the lead in place and maintaining electrical contact with it.
