The Boston Scientific MACH1 VL4.5 8F Coronary Guiding Catheter (REF H74934358740) is a single-use coronary guiding catheter designed to deliver consistent backup support, accurate torque transmission, and a smooth, large lumen for device delivery during percutaneous coronary procedures. The MACH1 platform is engineered to provide stable ostial engagement and predictable handling across a broad range of coronary anatomies.

Key Features
Stainless steel braided shaft engineered for 1:1 torque response and kink resistance.
Three-layer construction intended to balance pushability, support, and lumen integrity.
Large, smooth inner lumen designed to facilitate contrast delivery and device passage.
Soft, atraumatic distal tip configured to reduce vessel trauma at the ostium.
VL (Voda Left) 4.5 curve geometry shaped for left coronary engagement with extra backup support.
8F outer diameter providing increased lumen capacity for complex device delivery.
Lubricious coating along the working length to support navigation through tortuous vasculature.

Clinical Applications
Intended for use in percutaneous coronary diagnostic and interventional procedures.
Facilitates the introduction and exchange of interventional devices into the coronary vasculature.
Curve geometry suited for selective engagement of the left coronary system where extra backup is desired.
Suitable for procedures requiring larger-profile device delivery consistent with an 8F lumen.
