Alert Indications, Safety, and Warnings

Overview

Precise Placement. Secure Fixation.

Watch how Attain Stability Quad gives you more options for precise and secure lead placement in
non-apical pacing locations.

Active Fixation and Quadripolar Technology

1. Advanced Quadripolar Lead Technology

Reduces phrenic nerve stimulation with short bipolar spacing^2-4
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

Dislodgement During Slitting^*1,6

Dislodgement (6 Months)^†1,6

P = ns

Graph depicting dislodgement rate of 0.7% for Attain Stability Quad versus 2.0% for Attain Performa

*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

Reported Extractions as of January 2021⁷

Attain Stability Quad
Longest 14–15 months

Implant Duration Prior to Explants

Bipolar LV Lead with Side Helix (OUS)^‡
30 reported extractions, longest 46–47 months

Implant Duration Prior to Explants

^‡This lead is not and will never be FDA approved or available for use in the United States. This lead is no longer manufactured. The data included here is in regard to the lead's side helix mechanism, which is identical in design and function to the side helix on the Attain Stability Quad lead.

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
