The Boston Scientific MACH1 JR4 ST 8F Coronary Guiding Catheter (REF H749343586980) is a single-use interventional access catheter designed to deliver reliable backup support, smooth torque transmission and consistent lumen integrity during percutaneous coronary procedures. The MACH1 platform is engineered with a proprietary shaft construction intended to maintain shape retention and pushability when navigating tortuous anatomy.

Key Features
- JR4 (Judkins Right 4) curve shape configured for native right coronary artery engagement.
- ST (Side-hole) configuration to support perfusion during deep engagement.
- 8F outer diameter shaft providing a large inner lumen for device delivery and contrast injection.
- MACH1 shaft technology designed for high torque response, kink resistance and shape retention.
- Lubricious coating on the distal segment to facilitate smooth tracking.
- Atraumatic soft tip intended to reduce vessel trauma at the ostium.
- Single-use, sterile, packaged for procedural readiness.

Clinical Applications
- Diagnostic and interventional access to the coronary ostia.
- Support catheter for delivery of guidewires, balloons, stents and adjunctive interventional devices.
- Procedures requiring an 8F guiding lumen for complex device delivery or simultaneous device use.
- Cases where side-hole perfusion may be considered by the operator during deep or selective engagement.
