The Boston Scientific MACH1 KR3S 8F Coronary Guiding Catheter (REF H749343586540) is a single-use interventional access catheter from the MACH1 platform, designed to deliver predictable backup support, smooth tracking, and consistent torque transmission during percutaneous coronary procedures. The KR3S curve is intended for tailored ostial engagement, while the 8F lumen accommodates a broad range of interventional devices.

Key Features
Single-piece, full-length braided shaft engineered for 1:1 torque response and kink resistance.
KR3S preformed curve geometry for targeted coronary ostial engagement and supportive backup.
8F outer diameter with a large inner lumen to facilitate device delivery and contrast injection.
Atraumatic soft tip designed to reduce vessel trauma during cannulation.
Hydrophilic or lubricious coating per manufacturer specification to support smooth navigation. Not specified in the located sources for coating length.
Sterile, single-use configuration intended for use with compatible guidewires and interventional accessories.

Clinical Applications
Introduction and support of interventional devices into the coronary vasculature.
Selective angiography and contrast media delivery during diagnostic and interventional cardiology procedures.
Procedures requiring an 8F guide platform, including those involving larger profile devices, bifurcation strategies, or complex lesion access where additional lumen capacity is preferred.
Use by trained interventional cardiologists in catheterization laboratory settings.
