Medtronic (Minneapolis) reported FDA approval and launch of the DF4 High-Voltage Connector System, a right ventricular lead and connector used with implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) to detect and accurately treat potentially life-threatening heart rhythms. The DF4 Connector System helps simplify implantation procedures via a redesigned port and provides additional reliability by giving physicians visual confirmation of the lead connection to the device.
