The Boston Scientific MACH1 AL.75 ST 7F Coronary Guiding Catheter (REF H749343571080) is a single-use percutaneous guiding catheter engineered to deliver interventional devices to the coronary ostia. The MACH1 platform is designed for predictable torque response, strong backup support and a smooth inner lumen to facilitate device tracking during percutaneous coronary intervention (PCI).

Key Features
- Curve: Amplatz Left 0.75 (AL.75) with short tip (ST) configuration
- French size: 7F outer diameter for higher-profile device compatibility
- Construction: Multi-layer shaft with stainless-steel braid for torque transmission and kink resistance
- Inner lumen: PTFE-lined to reduce friction during device exchanges
- Atraumatic soft tip intended to reduce risk of vessel trauma at engagement
- Single-use, sterile packaging
- Length: Not specified in the located sources

Clinical Applications
- Selective engagement of the coronary ostia for contrast injection and PCI support
- Backup support for delivery of balloons, stents and other interventional devices
- Use cases where an Amplatz Left curve and a shorter tip geometry are preferred by the operator
- Procedures requiring a 7F guiding catheter lumen for compatible interventional equipment
