The Boston Scientific MACH1 RBL4 6F Coronary Guiding Catheter (REF H749343567360) is a single-use percutaneous coronary guiding catheter engineered to provide stable backup support and predictable coaxial engagement during diagnostic angiography and percutaneous coronary intervention (PCI). The MACH1 platform is designed to combine torque response, kink resistance, and a smooth inner lumen to facilitate device delivery throughout the coronary anatomy.

Key Features
Preformed RBL4 (Renal Backup Left) curve intended to provide enhanced backup support for left coronary engagement.
Outer diameter of 6 French for compatibility with standard radial and femoral access workflows.
MACH1 shaft construction designed for 1:1 torque transmission and kink resistance.
Lubricious inner lumen to support smooth passage of guidewires, balloons, stents and other interventional devices.
Atraumatic soft tip designed to reduce the risk of vessel trauma during engagement.
Radiopaque marker characteristics to aid fluoroscopic visualization.
Sterile, single-use device supplied in protective packaging.

Clinical Applications
Selective coronary angiography of the left coronary system.
Delivery and support platform for guidewires, balloon catheters, stents and adjunctive PCI devices.
Procedures requiring additional backup support for engagement of the left main and its branches.
Use in cardiac catheterization labs for diagnostic and interventional cardiology workflows.
