Quartet™ Quadripolar LV Lead

Revolutionizing CRT Pacing Options

The innovative Quartet lead features four pacing electrodes and ten pacing configurations to enable LV pacing at the preferred site without compromising lead stability for better management of heart failure patients.

Built on the proven QuickFlex™ µ lead platform for superb deliverability with exceptional stability and performance, the Quartet lead implant success rate in initial studies average approximately 97%.1-2

Quartet™ Left-Heart Lead
Overview

Four Narrow Electrodes

  • The Quartet lead enables greater pacing flexibility than unipolar or bipolar leads and provides more options for pacing complication avoidance.

IS4 Connector

  • IS4 connector enables 4 pacing electrodes in a single connector for streamlined implantation

Low Profile

  • 4.7 F lead body diameter for maneuverability
  • 4.0 F tip electrode designed to aid in accessing small or difficult-to-reach target branch veins

OptimTM Lead Insulation

  • Optim lead insulation is a hybrid insulation material–the first of its kind, developed specifically for cardiac lead use. It blends the biostability and flexibility of high-performance silicone rubber with the strength, tear resistance and abrasion resistance of polyurethane. This insulation allows for an abrasion-resistant, thin diameter lead.

S-Curve Fixation

  • The S-curve shape is designed to provide enhanced lead stability in a wide variety of vein sizes.

Steerable Tip

  • Distal tip angle can be controlled to maneuver the lead through venous anatomy.
