Sprint Quattro™ 6944
Steroid-Eluting, True Bipolar, Passive Fixation ICD Lead
True Bipolar Sensing and Two Defibrillation Coils
- Quadripolar technology
- More effective re-detection of VF1
More Efficient Pacing
- Greater than 750Ω pacing impedance2
- Low pacing thresholds-median pacing threshold at 1.0 V-0.20 ms
at 3 months2 - Steroid elution for reduced inflammation at the tissue interface
The new Sprint Quattro Haloe™ tip electrode, with greater than 750Ω impedance,2 is steroid eluting and platmized
Easy Introduction, Navigation and Handling
- Small 9 Fr introducer size (without guide wire)
- Isodiametric—even where lead body meets the coils
- Small lead body (8.2 Fr)
- Isoglide™ overlay provides slippery surface
Reliability
- Patented compression lumens designed to resist crush
- Built on the solid experience and reliability of over 80,000 Sprint leads sold worldwide
