Abstract
A system delivers combined ventricular assist device (VAD) therapy and chemical and/or biological therapy to modulate myocardial tissue growth in a heart after myocardial infarction (MI). The system includes an agent delivery device to release one or more agents to an MI region to modulate myocardial tissue growth in that region, and a VAD to enhance the effects of the one or more agents by reducing myocardial wall stress and the overall cardiac workload. In one embodiment, the system is an implantable system including an implantable agent delivery device and an implantable VAD for long-term use in a patient.
