St. Jude Medical has received CE mark approval for three new Quartet left ventricular (LV) leads, providing physicians with additional electrode spacing options and one new lead shape.


The additional spacing combinations will enable physicians to target the individual cardiac anatomies of patients who require support from cardiac resynchronization therapy pacemakers (CRT-P) and defibrillators (CRT-D).

The new quadripolar leads can be used with next-generation MultiPoint Pacing technology, which allows physicians to pace various locations on the left side of the heart.

In addition, the technology helps physicians to provide new option for patients who haven’t responded to CRT.

The design of the new leads is based on the company’s quadripolar LV lead technology. They feature additional spacing options on two new S-shape and one new double-bend lead designs.

St. Jude Medical medical director and vice president of medical affairs Philip Adamson said: "These lead choices allow physicians to identify what lead spacing option will work best for each patient so they can individualize care.

"The expanded selection of quadripolar pacing leads reinforces St. Jude Medical’s leadership in quadripolar pacing and heart failure treatment options."

The company said that some of the newly approved products are also magnetic resonance (MR)-conditional, including the Quadra Assura CRT-D and Quadra Assura MP CRT-D with MultiPoint pacing.

Physicians can also customize therapy using the Auto Vect Quartet test, which is designed to automatically guide programming of appropriate therapy options available and streamline workflow.
