The Boston Scientific MACH1 AL1 90 cm SH 8F Coronary Guiding Catheter (REF H749343583980) is a single-use coronary guiding catheter engineered to deliver predictable backup support, controlled torque response, and stable coaxial engagement during percutaneous coronary interventions. The MACH1 platform is designed to provide consistent shape retention and a smooth inner lumen to facilitate device delivery through the guiding catheter.

Key Features
- Curve: AL1 (Amplatz Left 1) shape for engagement of the left coronary system and select anatomies
- Working Length: 90 cm
- French Size: 8F outer diameter
- Tip Configuration: SH (Side Holes) to support perfusion during deep engagement
- Construction: Multi-layer shaft design intended to combine torque transmission, kink resistance, and back-up support
- Inner Lumen: Lubricious inner coating to facilitate smooth device tracking and delivery
- Use: Single-use, sterile, disposable

Clinical Applications
- Selective angiography and percutaneous coronary intervention (PCI) of the coronary arteries
- Anatomies where the AL1 curve provides suitable coaxial alignment and back-up support
- Procedures requiring an 8F lumen for delivery of larger interventional devices, atherectomy systems, or multiple-device techniques
- Cases in which side holes may help maintain distal coronary perfusion during deep or ostial engagement
