The Boston Scientific MACH1 IM 85cm 7F Coronary Guiding Catheter (REF H749343571220) is a single-use interventional guiding catheter designed to provide stable coaxial engagement and reliable backup support for percutaneous coronary access. The MACH1 platform combines a stainless-steel braided shaft with a soft, atraumatic tip to deliver a balance of pushability, torque transmission and lumen patency required during diagnostic and interventional workflows.

Key Features
- IM (Internal Mammary) curve shaped to facilitate selective engagement of the internal mammary artery and graft anatomy.
- 7F outer diameter compatible with a broad range of interventional devices; inner lumen dimensions: Not specified in the located sources.
- 85 cm working length suited to standard femoral and selected alternative access approaches.
- Stainless-steel braided shaft for 1:1 torque response and consistent backup support.
- Soft atraumatic tip designed to reduce the risk of vessel trauma during engagement.
- Lubricious inner lumen intended to support smooth device tracking and contrast delivery.
- Single-use, sterile packaged for procedural readiness.

Clinical Applications
- Percutaneous coronary interventions requiring selective IM artery or IM graft cannulation.
