The Boston Scientific ADDWIRE Extension Wire (REF H74922150012) is a sterile, single-use accessory engineered to extend the usable length of a compatible coronary guidewire. By providing additional length, the ADDWIRE supports the safe exchange of over-the-wire catheters, balloons, stents, and other interventional devices without losing distal wire position across the target lesion.

Key Features
Designed to mechanically connect to a compatible Boston Scientific coronary guidewire to increase total working length.
Intended to facilitate catheter and device exchanges while maintaining distal wire access.
Supplied sterile for single-use to support procedural workflow and reduce cross-contamination risk.
Manufactured by Boston Scientific under the ADDWIRE product line for coronary interventional use.
Compatibility, diameter, and extended length: Not specified in the located sources.

Clinical Applications
Use as an accessory during percutaneous coronary intervention (PCI) procedures requiring guidewire length extension.
Supports device exchange steps in complex coronary cases where wire position must be preserved.
Intended for use by trained interventional cardiologists in catheterization laboratory environments.
Specific indications, contraindications, warnings, and precautions: refer to the manufacturer Instructions for Use.
