The Boston Scientific MACH1 FR3.5 7F Coronary Guiding Catheter (REF H74934357010) is a single-use interventional catheter engineered to provide stable coronary ostial engagement, predictable torque transfer, and reliable backup support for the delivery of interventional devices during percutaneous coronary procedures. The MACH1 platform is built around a multi-layer shaft construction intended to balance pushability, kink resistance, and lumen integrity throughout the case.

Key Features
Curve type: FR3.5 (Femoral Right) preformed configuration for right coronary artery access.
Outer diameter: 7F sizing to accommodate larger interventional devices and dual-device techniques.
Multi-layer shaft design intended to support torque response and shape retention.
Smooth inner lumen engineered to facilitate device tracking and contrast delivery.
Atraumatic soft tip designed to reduce the risk of vessel trauma at the ostium.
Single-use, sterile packaged device.

Clinical Applications
Intended for use in percutaneous coronary interventions where guidewires, balloon catheters, stents, and other interventional devices are introduced into the coronary vasculature.
FR3.5 curve geometry typically selected for engagement of the right coronary artery via femoral access.
Suitable for procedures requiring 7F-compatible device delivery, including selected complex PCI workflows.
