The Boston Scientific MACH1 RBR3.5 6F Coronary Guiding Catheter (REF H749343567390) is a single-use percutaneous guiding catheter intended to facilitate the introduction and placement of interventional and diagnostic devices into the coronary vasculature. The RBR3.5 curve is configured for engagement of right coronary bypass grafts, while the MACH1 platform is engineered to deliver consistent backup support, torque response, and lumen integrity throughout the procedure.

Key Features
Three-layer shaft construction designed to balance pushability, torque transmission, and kink resistance.
PTFE inner lumen intended to support smooth device tracking and reduce friction during exchanges.
6F outer diameter with a large inner lumen to accommodate contemporary interventional devices.
Pre-formed RBR3.5 (Right Bypass) curve shaped for selective engagement of right-sided saphenous vein grafts.
Atraumatic soft tip designed to reduce the potential for vessel trauma during cannulation.
Radiopaque marker to support fluoroscopic visualization.

Clinical Applications
Selective cannulation of right coronary artery bypass grafts during diagnostic angiography.
Support catheter for percutaneous coronary interventions involving right-sided bypass graft anatomy.
Delivery conduit for guidewires, balloon catheters, stents, and other compatible interventional devices.
Use within catheterization laboratory workflows requiring stable backup support in graft anatomy.
