The Boston Scientific MACH1 VL4.5 SH 7F Coronary Guiding Catheter (REF H74934357800) is a single-use interventional catheter designed to facilitate selective cannulation of the coronary ostia and provide a conduit for the delivery of interventional devices during percutaneous coronary procedures. The MACH1 platform is engineered to combine stable backup support, responsive torque transmission, and a smooth inner lumen for consistent device tracking.

Key Features
- MACH1 construction with a multi-layer shaft engineered for 1:1 torque response and kink resistance.
- VL4.5 (Voda Left 4.5) curve shaped to provide extra backup support in the left coronary system.
- Short tip (SH) configuration to assist coaxial engagement of the coronary ostium.
- 7F outer diameter compatible with standard 7F introducer sheaths and large-bore interventional devices.
- Lubricious inner lumen to support smooth passage of guidewires, balloons, stents, and adjunctive devices.
- Atraumatic soft tip intended to reduce the risk of vessel trauma during engagement.
- Radiopaque marker to support fluoroscopic visualization.

Clinical Applications
- Selective cannulation of the left coronary artery during diagnostic and interventional coronary procedures.
- Conduit for delivery of guidewires, balloon catheters, stents, and other interventional devices.
- Cases requiring enhanced backup support for complex coronary anatomy or higher-profile device delivery.
