A Novel Device to Perform Cardiac Resynchronization Therapy for the Treatment of Congestive Heart Failure

Stanford University, 2004 - $18,369

This E-Team developed a device that simplifies the process of implanting Cardiac Resynchronization Therapy (CRT) devices in human hearts. CRT devices (e.g., pacemakers) are used to treat instances of congestive heart failure (CHF). Implanting them requires attaching electrical leads to the ventricular walls of the heart, which in turn cause the heart to contract at regular intervals. This E-Team's device allows surgeons to access the left ventricular wall (the harder of the two walls to reach) by passing that electrical lead through the right ventricle, rather than routing it separately into the left ventricle. This approach allows for faster procedures with fewer surgical obstacles, minimizing the chances for failure.

CHF is a major (and growing) health problem, especially in the US. While pacemakers currently improve the lives of many people with CHF, the failure rate for the implant procedure is about 8%. Furthermore, there are many patients who are too sick to undergo such major surgery. Because this device lessens the operating time and avoids the obstacles surrounding the left ventricle, it could presumably make an impact in both of these groups.
