Key features and technical specifications

Key features and technical specifications

The RELIANCE 4-FRONT Leads are 7.3F (2.4 mm) (8F / 2.6 mm introducer), steroid-eluting, endocardial cardioversion/defibrillation and pace/sense leads available in extendable/retractable models as well as in passive fixation models. These leads utilize the DF4 connector and incorporate the IROX™ (iridium oxide) coating on the tip electrode. The silicone lead body has a lubricious coating, and the electrode coils are silicone-backfilled.

Passive-Fixation Features

Design: Leveraged from successful FINELINE 2 family. 12 mm Tip to RV Coil spacing is identical to RELIANCE. Incorporates a flexible neck region and IROX coating for improved pacing performance.

Active-Fixation Features

Terminal pin-driven extendable/retractable fixation helix: Rotating the knob of the EZ-4TM Connector tool rotates the terminal pin which extends / retracts the helix. The IROX coated platinum-iridium helix anchors the pacing electrode to the endocardial surface without support of trabecular structures, offering various lead placement possibilities for the tip electrode in the right ventricle.
Mapping: The RELIANCE 4-FRONT tip and helix design allows mapping even with the helix fully retracted. Helix is flush to prevent snagging while enabling mapping.
Fluoroscopic markers: The RELIANCE 4-FRONT active fixation model incorporates a radiographic marker system to enable clear visualization of the helix position under fluoroscopy.
