The Medtronic Sprint Quattro Secure MRI SureScan Defibrillation Lead, REF 6947, is a transvenous, silicone-insulated ICD lead engineered for chronic implantation in the right ventricle. As part of Medtronic's Sprint Quattro family, it is designed to deliver high-voltage defibrillation therapy as well as bradycardia pacing and sensing when connected to a compatible Medtronic ICD or CRT-D pulse generator. The SureScan designation indicates the lead is part of Medtronic's MR Conditional system portfolio, intended to support MRI scanning under defined conditions specified in the manufacturer's MRI technical manual.
Key Features
Quadripolar DF-1/IS-1 connector configuration for compatibility with Medtronic ICD generators
Active fixation via extendable/retractable helix for stable right ventricular positioning
Dual shocking coils (RV and SVC) for high-voltage defibrillation therapy
Silicone insulation with polyurethane overlay segments for handling and durability
Steroid-eluting tip designed to support stable pacing thresholds
MR Conditional labeling as part of the Medtronic SureScan system, subject to MRI technical manual conditions
Designed for transvenous implantation through standard introducer techniques
Clinical Applications
Defibrillation therapy delivery for patients indicated for an implantable cardioverter defibrillator
Bradycardia pacing and intracardiac sensing in the right ventricle
Use as the RV defibrillation lead within single-, dual-, or triple-chamber ICD/CRT-D systems
Patient populations where MR Conditional system labeling is a procurement consideration
