This NSF-funded and Stony Brook-led project includes collaborators from seven leading universities and centers working together to develop far more realistic cardiac device models than what currently exists. The CyberCardia platform can be used to test and validate medical devices faster and at a far lower cost than existing methods. CyberCardia, which is funded through NSF's cyber-physical systems program, can also be used to design optimal, patient-specific device therapies, thereby lowering the risk to the patient.
