The Boston Scientific MACH1 RBR4 SH 6F Coronary Guiding Catheter (REF H749343567610) is a single-use interventional cardiology guiding catheter from the MACH1 family, designed to deliver consistent backup support, predictable torque response, and a stable platform for the delivery of interventional devices into the coronary arteries.

Key Features
Single-piece full-length braided shaft engineered for 1:1 torque transmission and pushability.
RBR4 (Right Backup) curve providing enhanced passive support against the contralateral aortic wall for the right coronary artery.
SH (Side Holes) configuration intended to help maintain perfusion during deep or selective engagement.
6F (French) outer profile compatible with standard radial and femoral interventional workflows.
Atraumatic soft tip designed to reduce the risk of vessel trauma during cannulation.
Lubricious inner lumen to facilitate smooth device delivery and exchange.

Clinical Applications
Selective cannulation and contrast injection of the coronary ostia.
Delivery and support platform for guidewires, balloon catheters, stents, and other interventional devices during percutaneous coronary intervention (PCI).
Procedures requiring enhanced backup support of the right coronary artery anatomy.
Diagnostic and interventional cardiac catheterization workflows where side-hole perfusion is preferred.
