Attain Stability Quad™ is designed with active fixation and quadripolar lead technology to allow for precise placement and secure fixation during implant. This design provides more flexibility in pacing location and reduces the risk of lead dislodgement.1

active fixation and Quadripolar technology 

1. ADVANCED QUADRIPOLAR LEAD TECHNOLOGY

  • Reduces phrenic nerve stimulation with short bipolar spacing2-4
  • Improves thresholds and longevity with steroid on all electrodes5
  • Enables multiple point pacing (MPP)
  • Approved for 1.5T and 3T full body MRI scanning   

2. Unique Side Helix Mechanism for Active Fixation

  • Enables precise and secure lead placement
  • Eliminates the need to wedge 
  • Integrates a mechanical stop and adhesive backfill for prevention of over-rotation and vein tissue pinching

Designed with extraction in mind

Helix straightens and elongates below expected extraction forces, enabling removal from the vein — similar to passive fixation leads.6

Safety

Attain Stability Quad helix is 0.25 mm away from lead body.

  • Vessel cross-sectional analysis indicates a 1 mm average distance between a vein and the nearest artery.1  This distance was taken into account when designing the side helix.
  • The helix is positioned 0.25 mm away from the lead body — creating a 4x safety margin between the vein and artery.
  • No lead dislodgements reported within 12 months of follow-up.1
