What is a Medtronic Sprint Fidelis Defibrillator Lead?
Manufactured by Medtronic, Inc., Sprint Fidelis leads are specific models of cardiac electrodes (thin wires) that connect an implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) directly to the heart. ICDs and CRT-Ds are devices that protect patients when irregular, life-threatening heart rhythms occur.
