Patent abstract
A myocardial infarction patch for placement over a myocardial infarction includes an electroactive polymer (EAP) structure. Varying electricity supplied to the EAP structure causes the patch to expand and contract over the myocardial infarction. The expansion and contraction of the patch can be coordinated with the expansion and contraction of the heart. The electricity is provided to the EAP via a pacemaker, defibrillator, ICD or similar pulse-generating device. Causing the patch to expand and contract against the myocardial infarction can improve the ejection fraction of the heart.
