Abstract
An appliance for electrically stimulating tissue contractions of a living organism has circuitry for applying a stimulation potential to the tissue region to be stimulated and for applying a reference potential circuitry for detecting to the body of the living organism, stimulated tissue contractions. Following stimulation the stimulated tissue contraction is measured by a bipolar electrode between two adjacent tissue regions, the stimulation potential applied being to at least one of these tissue regions for the purpose of stimulating a tissue contraction.
Claims9
A medical appliance adapted for in vivo implantation in an organism comprising:
- means for electrically stimulating tissue contractions in said organism having a terminal carrying a stimulation potential and a terminal carrying a reference potential;
- means for detecting stimulated tissue contractions having an input side with two terminals, said means for detecting forming a signal corresponding to the potential difference between said two terminals;
- means for applying said reference potential to said organism;
- a bipolar electrode having two contact parts adapted for in vivo contact with tissue to be stimulated;
- and
- means, for the purpose of stimulating a tissue contraction, for connecting said terminal carrying said stimulation potential to at least one of said two contact parts of said bipolar electrode and for connecting said terminal carrying said reference potential to said means for applying said reference potential, and following stimulation, for connecting one of said two terminals of said means for detecting to one of said two contact parts of said electrode and for connecting the other of said two terminals of said means for detecting to the other of said two contact parts of said electrode.
