The Boston Scientific MACH1 CLS3 SH 7F Coronary Guiding Catheter (REF H749343575770) is a single-use interventional catheter designed to provide stable cannulation of the coronary ostia and a supportive platform for the delivery of guidewires, balloons, stents and other interventional devices during percutaneous coronary procedures. The MACH1 platform is engineered to deliver consistent torque transmission, kink resistance and a smooth inner lumen to facilitate device tracking.

Key Features
- CLS3 Short Hook (SH) curve configured for left coronary system support with a shorter secondary curve geometry.
- 7F outer diameter providing an enlarged inner lumen for multi-device interventional strategies.
- MACH1 shaft technology intended to combine pushability, torque response and kink resistance.
- Lubricious inner lining to support smooth device passage and reduce friction during exchanges.
- Atraumatic soft tip designed to minimize vessel trauma during ostial engagement.
- Single-use, sterile packaging for procedural readiness.

Clinical Applications
- Selective angiography and percutaneous coronary intervention (PCI) of the coronary arteries.
- Delivery of interventional devices including guidewires, balloon catheters and coronary stents.
- Cases requiring enhanced backup support with the CLS3 SH curve geometry.
- Procedures where 7F lumen capacity is preferred for complex or multi-device strategies.
