The Medtronic Sprint Quattro MRI SureScan ICD Defibrillation Lead (REF 6946M) is a transvenous, silicone-insulated, single-pass defibrillation lead engineered for chronic right-ventricular implantation. As part of the Sprint Quattro family, it integrates dual high-voltage shocking coils with a true bipolar pace/sense electrode pair and is labeled as a SureScan component intended for use within an MR Conditional Medtronic ICD or CRT-D system.
Key Features
Dual-coil configuration with right-ventricular (distal) and superior vena cava (proximal) shocking electrodes for high-voltage defibrillation therapy.
True bipolar sensing and pacing via a tip and ring electrode for discrete near-field ventricular signal acquisition.
Active fixation with an extendable/retractable helix to facilitate site selection and stable chronic fixation.
SureScan labeling for use as part of an MR Conditional Medtronic system, subject to the conditions of use defined in the system manual.
Silicone insulation with polyurethane segments and a steroid-eluting collar at the distal electrode designed to mitigate acute pacing thresholds.
DF-1/IS-1 trifurcated proximal connector compatible with Medtronic ICD and CRT-D pulse generators that accept this configuration.
Clinical Applications
Delivery of ventricular defibrillation, cardioversion and antitachycardia pacing therapies as part of an implantable cardioverter defibrillator system.
Chronic ventricular pacing and sensing in patients indicated for ICD or CRT-D therapy.
Use in patients for whom conditional MRI scanning may be required when implanted as part of a complete Medtronic SureScan system, in accordance with the manufacturer's MRI technical manual.
