The Boston Scientific MACH1 IM SH 8F Coronary Guiding Catheter (REF H749343581290) is a single-use percutaneous catheter engineered to provide stable coronary ostial engagement and reliable backup support during diagnostic angiography and percutaneous coronary interventions. The MACH1 platform combines a full-body braided shaft with an atraumatic soft tip to deliver predictable torque response, kink resistance and consistent lumen patency throughout the procedure.

Key Features
- IM SH (Internal Mammary Short) curve intended for selective engagement of the internal mammary artery and graft anatomy.
- 8F outer diameter guiding catheter offering a large lumen for device delivery and contrast injection.
- Full-length stainless steel braid for one-to-one torque and shaft stability.
- Soft, atraumatic distal tip designed to reduce the risk of ostial trauma during cannulation.
- Lubricious inner lumen to facilitate smooth device tracking and exchange.
- Radiopaque marker for fluoroscopic visualization.
- Sterile, single-use packaging.

Clinical Applications
- Selective coronary angiography and percutaneous coronary intervention (PCI).
- Cannulation of the internal mammary artery and IMA bypass grafts where a short curve is preferred.
- Delivery of guidewires, balloons, stents and other interventional devices to target coronary anatomy.
- Use in cath lab and hybrid OR settings by trained interventional cardiologists.
