Abstract

An activator device for activation of cardiac tissue having a stint for placement within the interior volume of a natural heart adjacent cardiac tissue thereof. The device also includes a yoke for placement around a portion of the exterior surface of the natural heart in general alignment with the stint and connected to the stint by at least one cord. The device provides a simple yet reliable mechanism for assisting in extended activation of a natural heart with minimal impact and intrusion.
