The Boston Scientific MACH1 AL.75 ST SH 8F Coronary Guiding Catheter (REF H749343581190) is a single-use interventional guiding catheter designed to deliver intravascular devices to the coronary anatomy. The MACH1 platform is engineered for consistent backup support, predictable torque transmission, and a smooth inner lumen to facilitate device delivery during percutaneous coronary procedures.

Key Features
Amplatz Left 0.75 (AL.75) curve geometry for targeted coronary ostial engagement
Side-hole (ST SH) configuration intended to support perfusion when the catheter tip is engaged
8 French outer diameter for compatibility with larger or multi-device interventional workflows
MACH1 shaft construction designed for 1:1 torque response and kink resistance
Smooth inner lumen intended to facilitate device tracking and deliverability
Atraumatic soft tip designed to reduce vessel trauma at engagement
Working length and inner diameter: Not specified in the located sources
Sterile, single-use device

Clinical Applications
Percutaneous coronary intervention (PCI) requiring Amplatz Left curve support
Delivery of balloons, stents, and adjunctive interventional devices to the coronary arteries
Cases requiring 8F access for bulky devices, complex lesion preparation, or dual-device techniques
Procedures where side-hole perfusion characteristics are clinically preferred
