The Boston Scientific MACH1 IM 8F Coronary Guiding Catheter (REF H74934358260) is a single-use interventional catheter designed to provide reliable coronary ostial engagement, predictable torque transmission, and stable backup support during percutaneous coronary procedures. The MACH1 platform is engineered to combine a smooth inner lumen with a supportive shaft for consistent device delivery.

Key Features
- Curve: IM (Internal Mammary) configuration for selective engagement of the internal mammary artery and graft anatomy.
- French size: 8F outer diameter for accommodating larger interventional devices.
- Shaft design: Multi-layer construction intended to balance pushability, kink resistance, and torque response.
- Inner lumen: Lubricious liner designed to support smooth device tracking and contrast delivery.
- Atraumatic soft tip: Designed to reduce vessel trauma during ostial engagement.
- Sterility: Supplied sterile for single-use only.

Clinical Applications
- Selective angiography and interventional access of the internal mammary artery (IMA) and IMA grafts.
- Support catheter for delivery of guidewires, balloon catheters, stents, and other interventional devices.
- Diagnostic and interventional coronary procedures requiring an IM-shaped guiding catheter.
- Procedures requiring an 8F working channel for larger or multiple device delivery.
