Abstract
Treatment of cardiac tissue via an implantable heart treatment device is described. A device embodiment includes, but is not limited to, a substrate configured for implantation within a body; an electromagnetic signal generator coupled to the substrate and configured to generate one or more electric signals configured to stimulate one or more tissues of a heart within the body; and an energy-carrier molecule delivery device coupled to the substrate and configured to supply one or more non-oxygen cellular energy sources to one or more tissues of the heart within the body.
Claims21
An implantable heart treatment device, comprising:
- a substrate configured for implantation within a body;
- an electromagnetic signal generator coupled to the substrate and configured to generate one or more electric signals configured to stimulate one or more tissues of a heart within the body;
- an energy-carrier molecule delivery device coupled to the substrate and configured to supply one or more non-oxygen cellular energy sources to one or more tissues of the heart within the body;
- and
- control circuitry configured to generate one or more controls signals to activate one or more of the electromagnetic signal generator and the energy-carrier molecule delivery device during a fibrillation event of the heart.
