The Boston Scientific MACH1 KR4H SH 6F Coronary Guiding Catheter (REF H749343566520) is a single-use coronary guiding catheter engineered to deliver predictable torque transmission, reliable backup support, and atraumatic coaxial engagement during percutaneous coronary procedures. The MACH1 platform combines a stiff proximal shaft with a softer, atraumatic distal tip to facilitate device delivery while maintaining ostial stability.

Key Features
Stainless steel braided shaft construction for 1:1 torque response and kink resistance.
Tri-layer shaft design balancing pushability, lumen integrity, and lubricity.
Soft, atraumatic distal tip intended to reduce vessel trauma during engagement.
6F outer diameter offering an inner lumen sized for contemporary interventional devices.
KR4H SH curve geometry intended for coronary access in selected anatomies with a short-tip configuration.
Smooth inner surface to support contrast injection and device tracking.

Clinical Applications
Introduction of interventional and diagnostic devices into the coronary vasculature.
Delivery of contrast media to the coronary arteries.
Use as a conduit during percutaneous coronary intervention (PCI) workflows.
Procedures requiring stable backup support during device exchange and advancement.
