St Jude Medical has announced the launch and CE mark approval for three new Quartet left ventricular (LV) leads.
The leads are designed to offer additional electrode spacing options and one new lead shape; two leads are S-shape and one features a new double-bend design. The additional spacing combinations are aimed to more effectively target the individual cardiac anatomies of patients who need support from cardiac resynchronisation therapy pacemakers (CRT-P) and defibrillators (CRT-D).
“Heart and blood vessel anatomy vary from patient to patient so having multiple sizes and spacing options with the Quartet quadripolar lead helps me to treat all of my patients in need of cardiac resynchronisation therapy. We are now able to place the quadripolar lead in the best possible location for that patient, capturing more cardiac tissue to give heart failure patients the best opportunity to respond,” says Sami Pakarinen, Helsinki University Central Hospital in Helsinki, Finland.
The newly-approved additional quadripolar lead options are used with MultiPoint Pacing technology. The addition of this technology, according to a company press release, is intended to enable physicians to program a single Quartet LV lead to pace multiple sites on the left side of the heart, to give the clinician more choices to improve patient responses to therapy, and reduce the likelihood of costly and invasive lead revision through a second intervention procedure.
