Left-heart leads
Attain™ Performa™ MRI SureScan™ lead
The Attain™ Performa™ MRI SureScan™ lead is part of our cardiac resynchronization therapy (CRT) device system.
Description
Our Attain™ Performa™ MRI SureScan™ lead is part of our cardiac resynchronization therapy (CRT) device system, which allows you to personalize CRT. It offers:
- Three lead shapes for varying patient anatomies
- Steroid on all electrodes to improve thresholds and longevity1
- Short bipolar spacing to reduce phrenic nerve stimulation occurrence2,3
Product details
Quadripolar LV lead with wide electrode spacing
- Larger electrical field — phrenic nerve stimulated

Attain™ Performa™ with short bipolar spacing
- Smaller electrical field — phrenic nerve not stimulated

VectorExpress™ LV automated test
Provides clinically actionable data for all 16 vectors — in 2 minutes to4:
- Select a pacing location
- Maximize longevity
- Optimize CRT response
The 2.0 version of our VectorExpress™ LV automated test optimizes CRT response with LV electrical delay:
- RV sense to LV sense
- RV pace to LV sense

Multiple point pacing (MPP)
- Pacing from two LV electrodes provides another option for non-responders
- Fully compatible with AdaptivCRT™, EffectivCRT™ diagnostic, and EffectivCRT™ during atrial fibrillation (AF)
- Five new vectors added to allow for multiple point pacing
- VectorExpress™ 2.0 displays longevity information for MPP vectors as well as single-site vectors
