The Boston Scientific MACH1 Q3.5 SH 7F Coronary Guiding Catheter (REF H749343572970) is a single-use interventional guiding catheter designed for selective coronary angiography and percutaneous coronary intervention (PCI). The MACH1 family is engineered to deliver predictable torque response, reliable backup support, and consistent ostial engagement to facilitate device delivery through the coronary anatomy.

Key Features
- MACH1 platform built for high backup support and stable coronary engagement.
- Q3.5 SH curve shape configured for short, horizontal or shepherd-crook coronary takeoffs.
- 7F outer diameter providing a large internal lumen for multi-device PCI strategies including kissing balloon, bifurcation, and atherectomy support.
- Braided shaft construction intended to deliver 1:1 torque transmission and kink resistance.
- Lubricious inner lumen to ease device tracking and reduce friction during exchanges.
- Atraumatic soft tip designed to minimize vessel trauma at the ostium.
- Sterile, single-use packaged device.

Clinical Applications
- Selective coronary angiography and percutaneous coronary intervention.
- Delivery and support for balloon catheters, stents, and adjunctive PCI devices.
- Procedures requiring enhanced backup support in complex coronary anatomy.
- Suitable for cases needing a large 7F lumen for two-stent bifurcation or specialty device techniques.
