The Boston Scientific MACH1 AL1 SH 7F Coronary Guiding Catheter (REF H74934357680) is a single-use interventional guiding catheter designed to facilitate the introduction and support of interventional and diagnostic devices into the coronary vasculature. The MACH1 family is engineered for consistent torque transmission, a supportive shaft, and a soft atraumatic tip to aid in stable ostial engagement during percutaneous coronary procedures.

Key Features
Amplatz Left 1 (AL1) curve in a Short (SH) length configuration for tailored coronary engagement.
7 French outer diameter providing a generous inner lumen for multi-device techniques.
MACH1 shaft technology designed for 1:1 torque response and kink resistance.
Soft, tapered atraumatic distal tip to reduce vessel trauma during cannulation.
Lubricious inner lumen intended to support smooth device tracking and exchanges.
Radiopaque marker characteristics to support fluoroscopic visualization (refer to IFU).

Clinical Applications
Introduction of interventional and diagnostic devices into the coronary arteries.
Support during percutaneous coronary intervention (PCI) procedures where AL1 geometry is appropriate.
Cases requiring additional backup support for complex coronary anatomy.
Use as a conduit for balloon catheters, guidewires, stents, and other compatible devices, per the manufacturer's Instructions for Use.
