The Boston Scientific MACH1 CLS3 6F Coronary Guiding Catheter (REF H749343565730) is a single-use guiding catheter intended to facilitate the introduction and positioning of interventional devices during percutaneous coronary procedures. The MACH1 family is engineered to deliver predictable backup support, responsive torque transmission and a smooth inner lumen for device delivery.

Key Features
Preformed CLS3 (Contralateral Support) curve geometry intended for selective coronary engagement.
6F outer diameter compatible with standard radial and femoral access workflows.
Braided shaft construction designed to balance pushability, torque response and kink resistance.
Lubricious inner lumen to support smooth passage of balloons, stents and other interventional devices.
Atraumatic soft tip designed to reduce the risk of vessel injury during ostial engagement.
Radiopaque markers/materials to support fluoroscopic visualization.

Clinical Applications
Use as a conduit for the delivery of interventional cardiology devices to the coronary anatomy.
Supports diagnostic and percutaneous coronary intervention (PCI) procedures requiring enhanced backup support.
Suitable for cases where a contralateral support curve facilitates ostial cannulation and guide stability. Clinician discretion applies; use according to the manufacturer's Instructions for Use.
