Attain Stability Quad

Attain Stability™ Quad MRI SureScan™ active fixation LV lead is designed with active fixation and quadripolar lead technology to allow for precise placement and secure fixation during implant.


Now celebrating over 100,000 patients implanted with Attain Stability Quad

Lead with confidence. Precise placement. Secure fixation. Confident extraction.

Attain Stability Quad allows for precise placement, secure fixation during implant, more flexibility in pacing location, and reduces the risk of lead dislodgement.1 Watch how Attain Stability Quad gives you more options for precise and secure lead placement in non-apical pacing locations.

Product details

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

Reduced risk for lead dislodgement

  • 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

*Based on a retrospective study comparing dislodgements to Attain Performa.
Ad-hoc analysis conducted comparing post-implant dislodgement rates between Attain Performa (Model 4298) and Attain Stability Quad (Model 4798) leads (p = 0.098, two-sided Fisher’s Exact Test). Data were collected in a similar fashion in both studies.

Designed with extraction in mind

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

  • 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
