The Boston Scientific MACH1 AL1 ST 8F Coronary Guiding Catheter (REF H749343581030) is a single-use interventional guide catheter designed to deliver and support coronary devices during percutaneous procedures. The MACH1 platform is engineered for predictable torque response, stable ostial engagement and a large, consistent inner lumen to facilitate device passage.

Key Features
Amplatz Left 1 (AL1) curve in a short-tip (ST) configuration for targeted coronary ostial engagement.
8F outer diameter compatible with standard interventional access sheaths.
Full-length braided shaft construction intended to support 1:1 torque transmission and kink resistance.
Large, uniform inner lumen to accommodate balloons, stents and adjunctive interventional devices.
Atraumatic soft tip designed to reduce vessel trauma at the ostium.
Lubricious inner coating intended to support smooth device tracking and delivery.
Radiopaque construction to aid fluoroscopic visualization.
Supplied sterile for single patient use.

Clinical Applications
Intended for use in percutaneous coronary interventional procedures where an Amplatz Left curve provides suitable backup support.
Delivery and exchange of interventional devices including guidewires, balloon catheters and stent systems.
Selective contrast injection and pressure monitoring during diagnostic and interventional coronary workflows.
Cases requiring short-tip AL1 geometry for challenging ostial or anatomical configurations.
