The Boston Scientific MACH1 FCR4 7F Coronary Guiding Catheter (REF H749343572800) is a single-use interventional catheter designed to facilitate the delivery and exchange of intravascular devices during percutaneous coronary procedures. The MACH1 platform is engineered to combine a supportive proximal shaft with an atraumatic distal tip, helping interventional teams achieve stable ostial engagement and consistent device tracking through tortuous anatomy.

Key Features
- 7 French outer diameter shaft compatible with standard introducer sheaths.
- FCR4 (Femoral Curve Right 4) preformed curve intended for engagement of the right coronary ostium via femoral access.
- MACH1 multi-layer shaft construction designed to deliver 1:1 torque response and resistance to kinking.
- Large inner lumen intended to support contrast injection and simultaneous device delivery.
- Soft, atraumatic distal tip designed to reduce vessel trauma during cannulation.
- Lubricious inner surface intended to facilitate smooth advancement and withdrawal of interventional devices.
- Sterile, single-use packaging.

Clinical Applications
- Diagnostic and interventional coronary angiography requiring a stable guiding platform.
- Percutaneous coronary intervention (PCI) procedures involving the right coronary artery via the femoral approach.
- Delivery of balloon catheters, coronary stents, guidewires, and other compatible interventional devices.
- Procedures where predictable backup support and torque transmission are required.
