The Boston Scientific MACH1 JL3 7F Coronary Guiding Catheter (REF H749343576600) is a single-use, preformed Judkins Left 3.0 (JL3) shaped guiding catheter intended for use in percutaneous coronary intervention (PCI) procedures. Engineered as part of the MACH1 family, it is designed to deliver a predictable combination of backup support, torque response and lumen size for the introduction and exchange of interventional devices into the coronary vasculature.

Key Features
Preformed Judkins Left 3.0 (JL3) curve for selective engagement of the left coronary ostium.
7F outer diameter shaft sized for compatibility with a broad range of interventional devices.
MACH1 platform construction designed for 1:1 torque transmission and consistent shape retention.
Smooth inner lumen intended to support device tracking and contrast delivery.
Atraumatic soft tip designed to reduce the risk of vessel injury during ostial engagement.
Sterile, single-patient-use configuration.

Clinical Applications
Selective angiography and guiding support for the left coronary artery system.
Delivery of guidewires, balloon catheters, stents and other interventional devices during PCI.
Suitable as a workhorse guide where a standard JL geometry is preferred.
Procedures requiring a 7F guiding catheter lumen for device compatibility.
