Description

Precise placement and secure fixation

The Attain Stability™ Quad allows for more flexibility in pacing location and reduces the risk of lead dislodgement.1

Features

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 and promotes non-apical pacing
    • Integrates a mechanical stop and adhesive backfill for prevention of over-rotation and vein tissue pinching
Attain Stability™ Quad has quadripolar electrode spacing and a unique side helix.

Reduced risk for lead dislodgment

  • 81% reduction in LV lead dislodgement during catheter slitting†,1,6
  • 65% reduction in LV lead dislodgement at six months post-implant‡,1,6
  • May reduce the need for repeat procedures due to LV lead dislodgements1
  • May enable earlier patient discharge due to a reduced risk for lead dislodgement7

Designed with extraction in mind

Helix straightens and elongates below expected extraction forces, enabling removal from the vein — similar to passive fixation leads.8

Safety

  • Vessel cross-sectional analysis indicates a 1 mm average distance between a vein and the nearest artery.9  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 LV lead perforations reported within six months of follow-up.1
Learn how the unique side helix of Attain Stability™ Quad is positioned 0.25 mm away from the lead body.
