The Boston Scientific MACH1 FL3.5 7F Coronary Guiding Catheter (REF H74934357060) is a single-use interventional guiding catheter designed to facilitate selective cannulation of the coronary ostium and provide a stable conduit for the delivery of interventional devices during percutaneous coronary procedures. The MACH1 platform is engineered to combine torque response, kink resistance and consistent backup support to help operators achieve efficient case workflow.

Key Features
- FL3.5 curve configured for left coronary access with dedicated backup support characteristics.
- 7F (French) outer diameter compatible with multi-device and complex PCI workflows.
- Three-layer construction with stainless steel braid for 1:1 torque transmission and column strength.
- Soft, atraumatic distal tip intended to reduce the risk of vessel trauma during engagement.
- Lubricious inner lumen to support smooth advancement of balloons, stents and adjunctive devices.
- Large lumen geometry to support contrast injection and device exchange.

Clinical Applications
- Selective angiography and percutaneous coronary intervention (PCI).
- Delivery of interventional devices such as balloon catheters, coronary stents and guidewires.
- Procedures requiring enhanced passive backup support from the left coronary system.
- Suitable for use via standard arterial access techniques as determined by the treating physician.
