The Boston Scientific MACH1 IM 90cm 6F Coronary Guiding Catheter (REF H749343564460) is a single-use guiding catheter engineered to deliver predictable support, torque response, and lumen integrity during percutaneous coronary interventions. The IM (Internal Mammary) curve is shaped to facilitate selective engagement of the internal mammary artery and graft anatomy.

Key Features
- IM (Internal Mammary) preformed curve for selective IMA and graft cannulation
- 6F outer diameter compatible with standard radial and femoral access workflows
- 90 cm working length suited to coronary and graft access
- Multi-layer shaft construction designed for torque transmission and kink resistance
- Smooth atraumatic tip designed to reduce vessel trauma during engagement
- Lubricious inner lumen to support device delivery and contrast injection
- Sterile, single-use packaging

Clinical Applications
- Selective angiography and guiding support for the internal mammary artery
- Access to bypass grafts where IM curve geometry is appropriate
- Delivery conduit for coronary interventional devices including balloons, stents, and guidewires
- Diagnostic and interventional cardiac catheterization workflows
