The Boston Scientific MACH1 JL4 7F Coronary Guiding Catheter (REF H749343576620) is a single-use guiding catheter designed for selective cannulation of the left coronary artery using the Judkins Left 4.0 curve. Built on the MACH1 platform, it combines a stiff proximal shaft, a flexible atraumatic tip, and a lubricious inner lumen to deliver predictable torque response, strong backup support, and consistent device tracking during percutaneous coronary procedures.

Key Features
Judkins Left 4.0 (JL4) preformed curve for left coronary ostial engagement
7F (French) outer diameter shaft for compatibility with a wide range of interventional devices
MACH1 multi-layer shaft construction for 1:1 torque transmission and kink resistance
Soft, atraumatic distal tip designed to reduce vessel trauma during cannulation
Lubricious inner lumen to facilitate smooth advancement of balloons, stents and guidewires
Radiopaque tip marker to support fluoroscopic visualization
Sterile, single-use packaging

Clinical Applications
Selective angiography and contrast delivery to the left coronary artery
Conduit and support catheter during percutaneous coronary intervention (PCI)
Delivery of interventional devices such as balloons, stents and guidewires
Procedures via standard femoral access where a 7F guide is appropriate
