The Boston Scientific MACH1 BR1 Coronary Guiding Catheter (REF H74934356400) is an 80 cm, 6F single-lumen guiding catheter featuring the BR1 (Bypass Right 1) curve. It is designed to deliver interventional devices and contrast media into the coronary or bypass graft vasculature during percutaneous catheter-based procedures.

Key Features
Working length of 80 cm with a 6F outer profile to balance access reach and inner lumen capacity.
BR1 preformed curve geometry intended to facilitate engagement of right coronary bypass grafts.
MACH1 platform construction engineered for back-up support, torque response and lumen patency during device delivery.
Atraumatic soft tip designed to reduce the risk of vessel trauma at engagement.
Lubricious inner lumen to support smooth passage of guidewires, balloons and stent systems.

Clinical Applications
Selective cannulation of coronary ostia and saphenous vein or arterial bypass grafts where a BR1 curve is appropriate.
Delivery conduit for guidewires, angioplasty balloons, stents and other interventional accessories during percutaneous coronary intervention (PCI).
Injection of radiopaque contrast media for diagnostic coronary or graft angiography.
