Medtronic nets FDA approval of new connector system for ICDs, CRT-Ds
Medtronic has received FDA approval and launched its DF4 High-Voltage Connector system, a right ventricular lead and connector used with implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds).

The DF4 connector uses the same lead body as Medtronic’s Sprint Quattro lead, and the DF4 design includes fewer connections between the device and the defibrillation leads, according to the Minneapolis-based company. The DF4 connector has a single set-screw to connect the lead to the device and is available on several Medtronic ICDs and CRT-Ds, including the Protecta, Consulta and Secura portfolio of implantable defibrillators.
