The Boston Scientific CHOICE Extra Support Coronary Guidewire (REF H74912119012) is a workhorse PTCA guidewire designed to provide reliable backup support, predictable torque response, and consistent tip behavior during percutaneous coronary intervention (PCI) procedures. The Extra Support variant of the CHOICE family is intended to facilitate device delivery in challenging anatomies where additional shaft stiffness is desired.
Key Features
Extra support shaft designed to enhance backup during balloon and stent delivery.
Shapeable distal tip intended to support navigation and lesion access.
Hydrophilic and/or PTFE coatings on designated segments to support smooth device tracking (segment coverage: Not specified in the located sources).
Consistent 1:1 torque transmission characteristic of the CHOICE platform.
Radiopaque distal segment for fluoroscopic visualization.
Clinical Applications
Intended to facilitate the placement and exchange of intravascular devices during diagnostic and interventional coronary procedures.
Useful in cases requiring additional backup support for crossing tortuous, calcified, or resistant lesions.
Supports delivery of balloons, stents, and other compatible coronary devices through the coronary vasculature.
