Ultra-compact integrated cardiac pacemaker and distributed cardiac pacing system

摘要

The present invention includes a control unit that outputs a control signal, a cardiac stimulation unit that electrically stimulates cardiac tissue in response to the control signal, an electrocardiogram information detection unit that detects and outputs electrocardiogram information to the control unit, and a drive A power supply unit for supplying power, wherein the control unit outputs a control signal based on electrocardiogram information, and the power supply unit is a biofuel cell for extracting electrons by an oxidation reaction of biofuel, A fuel cell is composed of an anode electrode and a cathode electrode, on which an oxidase of a biofuel and a mediator are immobilized, and blood and / or body fluid is used as an electrolyte solution, and blood and / or It is a biofuel cell that uses biofuel and oxygen in body fluids, and is inserted into the tip of the catheter and implanted in the heart. There is no necessity on the ultra-compact integrated cardiac pacemaker. The object of the present invention is that the heart can be paced without the need for a lead wire that conventionally connects the electrode and the pacemaker body, and can be implanted into the heart only by catheter operation without incising the chest wall. It is an object of the present invention to provide an ultra-compact integrated cardiac pacemaker and a distributed cardiac pacing system that do not impose an extra burden on the wearer.
