Medtronic received FDA clearance for its DF4 High-Voltage Connector System, a right ventricular lead and connector, compatible with various implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds).
The device is made to be easier to implant thanks to a new port featuring visual confirmation and only one connection unlike previous leads that often needed up to three hookups.
From the announcement:
The DF4 connector uses the same lead body as Medtronic’s Sprint Quattro® lead, which has more than a decade of proven performance and a high safety and efficacy profile. The DF4 design includes fewer connections between the device and the defibrillation leads. Prior to the development of the DF4, traditional high-voltage connector systems required up to three connections. 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.
In addition to the U.S., the DF4 High-Voltage Connector System is approved for use and available in most geographies including Europe, Japan, Canada, and Australia.
