The Boston Scientific MACH1 RCB 8F Coronary Guiding Catheter (REF H74934358240) is a single-use interventional cardiology guiding catheter designed to deliver therapeutic and diagnostic devices to the coronary vasculature. The MACH1 family is engineered to combine backup support, smooth torque transmission and a refined tip for consistent vessel engagement during percutaneous coronary intervention.

Key Features
Curve configuration: RCB (Right Coronary Bypass) shape intended for engagement of right coronary bypass grafts and select native anatomies.
Outer diameter: 8F profile supporting larger interventional device passage.
Construction: Multi-layer shaft with stainless steel braid for 1:1 torque response and kink resistance.
Inner lumen: PTFE-lined for low-friction device tracking and contrast delivery.
Atraumatic soft tip designed to reduce the risk of vessel trauma at engagement.
Full-length radiopaque marker support for fluoroscopic visualization.
Sterile, single-use packaging.

Clinical Applications
Intended for use as a conduit for the delivery of interventional and diagnostic devices into the coronary arteries and bypass grafts.
Supports balloon catheters, stent delivery systems, guidewires and adjunctive interventional accessories.
Selected by operators when an RCB curve and 8F lumen are appropriate for the target anatomy and planned device strategy.
