The Boston Scientific MACH1 AL1 SH 8F Coronary Guiding Catheter (REF H74934358680) is a single-use interventional guiding catheter designed to facilitate stable coaxial engagement and device delivery during percutaneous coronary procedures. The MACH1 platform combines a stiff proximal shaft with a softer atraumatic distal tip to balance pushability, torque transmission, and vessel-friendly access.

Key Features
Amplatz Left 1 (AL1) Short curve geometry intended for selective coronary engagement.
8F outer diameter shaft for high-flow contrast injection and large-bore device compatibility.
Three-layer construction with stainless steel braid for 1:1 torque response and kink resistance.
Lubricious inner lumen to support smooth advancement of balloons, stents, and adjunct devices.
Soft, radiopaque distal tip designed to reduce vessel trauma and aid fluoroscopic visualization.
Single-use, sterile (EO) packaging for procedural readiness.

Clinical Applications
Introduction and support of interventional devices into the coronary vasculature.
Selective angiographic visualization of target coronary anatomy.
Backup support during complex PCI where 8F access and the AL1 SH curve are appropriate per operator assessment.
