The Boston Scientific MACH1 RBR3.5 SH 6F Coronary Guiding Catheter (REF H749343567600) is a single-use interventional guiding catheter from the MACH1 family, designed to deliver consistent torque response and predictable coronary ostial engagement. The RBR3.5 SH curve is intended to provide enhanced backup support for the right coronary artery in selected anatomies, while the 6F profile balances inner lumen capacity with low-profile vascular access.

Key Features
Full-length braided shaft engineered for 1:1 torque transmission and pushability.
Atraumatic soft tip designed to reduce the risk of vessel trauma during engagement.
RBR3.5 SH (Short) curve geometry for backup-style support in right coronary anatomy.
6F outer diameter for radial or femoral access compatible with common interventional workflows.
Hydrophilic-compatible MACH1 platform construction for smooth navigation through tortuous vasculature.
Large inner lumen to accommodate standard PCI device delivery.

Clinical Applications
Selective angiography and percutaneous coronary intervention (PCI) procedures.
Right coronary artery engagement requiring backup support curves.
Delivery and exchange of guidewires, balloon catheters and stent systems within the coronary tree.
Use as a conduit for diagnostic and interventional accessories during cardiac catheterization.
