Heart failure is a serious health problem in Europe and the United States, and a major contributor to public health spending. The HBS project is taking advantage of recent advances in the ability to design miniature electro-mechanical components capable of generating their own electrical energy from the surrounding mechanical energy. This work is paving the way for new self-powered cardiac pacemaker implants. They should significantly improve patient comfort at lower cost than current treatments by reducing the number of post-implant surgeries. In the long run, this project aims to reduce public health spending related to heart failure therapy.
The HBS project aims to develop a low-power cardiac pacemaker (5µW instead of 25µW in current pacemakers), powered by mechanical energy from a patient's own heart beats. The goal is to eliminate the need for batteries, which must be surgically replaced every six to ten years in conventional pacemakers. A second goal is to develop smaller cardiac stimulators. The objective is to develop less than one cm3 stimulator - eight times smaller than current models - that can be placed directly inside the heart, thus avoiding the need for intravenous cardiac leads.
