ABSTRACT:
Soft, multi-fingered resilient robotic fingers for selectively assisting heart ventricles or other organ to produce internal pressure and to pump blood, in synchrony with the systolic contraction of the ventricle or organ, as well as providing arrhythmia control of a beating heart. The apparatus is electrically-controlled and implantable. The plurality of soft fingers monitor and gently squeeze the heart (systole) or organ to enhance blood circulation and assist the heart or organ. The soft fingers work in harmony, by means of a micro-processor controlled solenoid or other linear robotic actuators such as metal-hydride actuators or polymeric artificial muscles, and a resilient body or a spring, to close once the solenoid is powered to retract away from the heart or organ when the solenoid is not powered. Monitoring electrodes can be affixed to the soft fingers. The power supply for the implanted device can be transcutaneously rechargeable batteries.
