The Boston Scientific MACH1 FCR3.5 6F Coronary Guiding Catheter (REF H749343562790) is a single-use interventional catheter engineered for diagnostic and therapeutic percutaneous coronary procedures. The MACH1 family is designed to deliver consistent backup support, accurate torque transmission, and a smooth inner lumen to facilitate device delivery during complex coronary interventions.

Key Features
- FCR3.5 curve tailored for selective access in coronary anatomy requiring an FCR (Femoral Curve Right) configuration.
- 6F (French) outer diameter compatible with standard interventional workflows.
- Full-length braided shaft for 1:1 torque response and pushability.
- Lubricious inner lining intended to support smooth passage of guidewires, balloons, and stent delivery systems.
- Atraumatic soft tip designed to reduce vessel trauma during engagement.
- Radiopaque marker for fluoroscopic visualization.
- Sterile, single-use packaging.

Clinical Applications
- Percutaneous coronary intervention (PCI) requiring stable guide support.
- Selective coronary artery cannulation and contrast injection.
- Delivery of interventional devices such as guidewires, balloon catheters, and stents into the coronary vasculature.
- Procedures performed via femoral access where an FCR-style curve is indicated by the operator.
