The Boston Scientific MACH1 AL1 ST SH 8F Coronary Guiding Catheter (REF H749343581140) is a single-use interventional guiding catheter designed to provide predictable shape retention, smooth tracking and reliable backup support during percutaneous coronary procedures. The MACH1 platform is engineered to translate operator input into precise catheter response at the ostium.

Key Features
Preformed AL1 (Amplatz Left 1) curve in the ST SH (Short Tip, Side Hole) configuration for ostial engagement and pressure dampening management.
8F outer diameter compatible with larger-bore interventional devices and complex PCI tooling.
Multi-layer shaft construction intended to deliver 1:1 torque transmission and kink resistance.
Smooth inner lumen designed to support device deliverability and contrast injection.
Side hole design intended to help maintain coronary perfusion and dampen pressure when fully engaged.
Atraumatic soft tip designed to reduce vessel trauma at the ostium.

Clinical Applications
Intended for use as a conduit for the introduction of interventional devices into the coronary vasculature.
Commonly selected for engagement of the right coronary artery and certain anomalous or shepherd's-crook anatomies where Amplatz-style backup is preferred.
Suitable as a workhorse guide for complex PCI scenarios requiring 8F-compatible equipment such as larger thrombectomy, atherectomy or dual-stent techniques, per operator discretion.
