The Boston Scientific MACH1 FL3 6F Coronary Guiding Catheter (REF H74934356050) is a single-use interventional catheter designed to provide reliable coronary ostial engagement and consistent backup support during percutaneous coronary procedures. The MACH1 platform combines a refined shaft construction with the FL3 curve geometry to assist clinicians in achieving stable cannulation and smooth device delivery.

Key Features
Pre-shaped FL3 (Left Femoral 3) curve intended for left coronary access via a femoral approach.
6F outer diameter profile compatible with standard interventional workflows.
MACH1 multi-layer shaft construction designed to balance pushability, kink resistance and torque transmission.
Smooth inner lumen intended to support passage of guidewires, balloons, stents and other 6F-compatible interventional devices.
Atraumatic soft tip designed to reduce vessel trauma at the engagement site.
Sterile, single-use packaging.

Clinical Applications
Intended for use as a conduit during percutaneous coronary diagnostic and interventional procedures, including guidewire, balloon and stent delivery.
FL3 geometry typically selected by operators seeking enhanced support for left coronary system engagement.
Suitable for catheterization laboratory and hybrid OR settings where 6F guiding access is required.
