The Boston Scientific CHOICE PT Extra Support Coronary Guidewire (REF H74912161011) is designed to provide reliable backup support and smooth tracking during percutaneous coronary intervention (PCI) procedures. Engineered with a polymer-jacketed distal segment and hydrophilic coating, it is intended to facilitate navigation through tortuous coronary anatomy while delivering the rigidity clinicians expect from an extra-support platform.

Key Features
Extra support shaft designed to enhance device deliverability in challenging coronary anatomy.
Polymer sleeve over the distal segment for consistent lesion crossing performance.
Hydrophilic coating on the distal portion to help reduce friction during advancement.
PTFE coating on the proximal shaft to support smooth catheter exchanges.
Shapeable distal tip to allow operator customization for vessel selection.
Radiopaque distal segment to aid fluoroscopic visualization.

Clinical Applications
Intended to facilitate the placement and exchange of intravascular catheters during diagnostic and interventional coronary procedures.
Suitable as a workhorse or support wire in PCI where additional backup is desired.
May assist device delivery across tortuous, calcified, or otherwise complex coronary lesions.
Refer to the manufacturer Instructions for Use for complete indications, contraindications, warnings, and precautions.
