The Boston Scientific INGEVITY MRI Passive-Fixation Pacing Lead (REF 7735) is a bipolar transvenous endocardial pacing lead intended for chronic implantation and connection to a compatible Boston Scientific pulse generator. The lead features a passive-fixation tined tip designed to engage trabeculated endocardium and is part of the INGEVITY MRI lead family, which carries MRI-conditional labeling when implanted as part of an approved ImageReady MR Conditional pacing system.

Key Features
Bipolar configuration with IS-1 BI proximal connector for compatibility with standard Boston Scientific IS-1 pulse generator headers.
Passive-fixation distal tip with silicone tines for stable engagement in atrial appendage or right ventricular trabeculae.
Steroid-eluting electrode designed to help reduce acute and chronic pacing thresholds.
Silicone insulation with polyurethane outer coating engineered for handling and long-term reliability.
MRI-conditional labeling when used within an ImageReady MR Conditional system per the manufacturer Instructions for Use.
Compatible with a stylet-driven delivery technique familiar to implanting physicians.

Clinical Applications
Chronic atrial or ventricular sensing and pacing in patients indicated for permanent cardiac pacing.
Use as a component of single- or dual-chamber bradycardia pacing systems.
Procurement for electrophysiology and cardiac rhythm management programs requiring MR-conditional lead inventory. Refer to the official Instructions for Use for indications, contraindications, warnings, and patient selection.
