DF-4 Connectors for Implantable Cardioverter Defibrillators Enter Use in the US

The DF-4 Connector was recently introduced by a joint group of CRM companies, physicians, and regulatory agencies as a way of easing the implant of ICDs by reducing defibrillation connections from three to one and by minimizing the number of set screws.  Prior to the development of the DF-4, traditional high-voltage connector systems required up to three connections.

For the implanting physician, the DF-4 has a single terminal pin connection that decreases chances of lead-to-port mismatch. Fewer connections and setscrews lessen complexity, and the improved terminal pin visibility is designed to encourage proper lead connection.  For the patient, the streamlined design of the DF-4 Connector system eliminates the yoke and minimizes bulk. This may provide increased patient comfort, particularly for those who are concerned about body image or are small in stature, and may lessen the risk of lead-to-can abrasion.

ICD systems with DF-4 are now available from St. Jude Medical, Boston Scientific, and Medtronic (which received approval for its DF-4 connector only this week).
