Quadripolar LV Lead


Quartet™ Quadripolar LV Lead

More pacing flexibility without compromising lead stability.

Built on the proven QuickFlex™ µ lead platform, the Quartet quadripolar LV lead offers superb deliverability with exceptional stability and performance. Studies reflect an implant success rate averaging approximately 97%.1,2

Better Management of Heart Failure Symptoms

We designed our groundbreaking quadripolar technology to enable improved management and outcomes for HF patients. With four electrodes and up to 14 pacing configurations, the quadripolar system enables left ventricular (LV) pacing at the preferred site without compromising lead stability, for better management of heart failure patients.3

HF patients who undergo implantation of unipolar and bipolar CRT devices may experience challenges such as phrenic nerve stimulation, high pacing thresholds and non-response to CRT therapy.4 Managing these challenges can result in longer implant times and surgical revisions.

Quadripolar technology can help you overcome these challenges by offering you more pacing flexibility without compromising lead stability.

Potential Benefits of Quadripolar Technology

  • Shorter implant times and decreased fluoroscopic exposure1,5
  • Fewer surgical revisions2
  • More basal pacing opportunities (pacing basally has been shown to be associated with improved outcomes)6,7

Overall, quadripolar technology can lead to greater CRT implant and postoperative efficiencies while providing improved CRT efficacy.

MRI Readiness

The Quartet quadripolar LV lead, when combined with approved devices, allows full-body, 1.5T and 3T MRI scans that meet certain scan conditions.*

  • Meets industry-standard MRI testing requirements
  • Capable of full body 1.5T and 3T MRI imaging scans

Multiple Shape and Spacing Options

  • Distal shape options include the Double Bend shape, Traditional S-shape, Traditional S-shape—wide spacing and Small S-shape.
  • Total electrode spacing options include 40, 47 and 60 mm.
 Four Quartet quadripolar LV lead shape options

Four Distinctly Spaced Electrodes

  • Enables greater pacing flexibility than unipolar or bipolar leads
  • Provides more options to help prevent pacing complications

IS4 Connector

  • Enables four pacing electrodes in a single connector for streamlined implantation

Low Profile

  • 4.7 F lead body diameter for maneuverability
  • 4.0 F tip electrode, which aids access to small targets or difficult-to-reach branch veins

Steerable Tip

  • Adjustable distal tip angle for enhanced maneuverability in venous anatomy

Optim™ Lead Insulation

  • First-of-its-kind hybrid insulation material
  • Developed specifically for cardiac lead use
  • Blends the biostability and flexibility of high-performance silicone rubber with the strength, tear resistance and abrasion resistance of polyurethane, allowing for superior abrasion resistance in a thin diameter lead8
