The Boston Scientific MACH1 IM Coronary Guiding Catheter (REF H749343561220) is an 85 cm, 6F guiding catheter shaped in the Internal Mammary (IM) configuration. It is engineered to provide consistent ostial engagement, smooth torque transfer, and dependable backup support for diagnostic access and interventional device delivery in the coronary vasculature.

Key Features
Pre-formed IM (Internal Mammary) curve intended for selective engagement of the internal mammary artery and bypass graft access.
Working length of 85 cm to support standard transfemoral and selected alternative access workflows.
6F outer diameter sized to balance lumen capacity for interventional devices with vascular access considerations.
MACH1 platform construction designed to deliver one-to-one torque response, kink resistance, and stable shape retention.
Smooth inner lumen intended to facilitate delivery of guidewires, balloon catheters, stents, and other interventional devices.
Atraumatic soft tip designed to reduce the risk of vessel trauma during engagement.

Clinical Applications
Selective angiography and intervention involving the left internal mammary artery (LIMA) and right internal mammary artery (RIMA) grafts.
Conduit for delivery of percutaneous coronary intervention (PCI) devices in graft-related procedures.
Cases requiring a stable IM-shaped guiding catheter with predictable backup support.
Use should be determined by qualified interventional cardiologists in accordance with the manufacturer's Instructions for Use.
