The Boston Scientific MACH1 JL3 SH 7F Coronary Guiding Catheter (REF H749343576660) is a single-use percutaneous interventional catheter designed to deliver predictable backup support, precise ostial engagement and smooth device tracking during coronary procedures. The MACH1 platform combines a stiff proximal shaft with a softer atraumatic distal tip to balance pushability, torque response and vessel safety.

Key Features
Judkins Left 3 (JL3) preformed curve optimized for left coronary ostium engagement in smaller aortic roots.
Short Tip (SH) configuration to facilitate coaxial alignment and reduce deep intubation risk.
7F outer diameter shaft providing a generous inner lumen for multi-device interventional workflows.
Three-layer shaft construction with stainless steel braid for 1:1 torque transmission and kink resistance.
Lubricious inner lining intended to support smooth advancement of guidewires, balloons and stents.
Atraumatic soft distal tip designed to mitigate ostial trauma during cannulation.

Clinical Applications
Diagnostic and interventional access to the left coronary artery system via femoral or alternative arterial approaches.
Delivery and exchange of percutaneous coronary intervention (PCI) devices including guidewires, balloon catheters and stents.
Procedures requiring stable backup support with a short-tip Judkins Left curve.
Use by trained interventional cardiologists in catheterization laboratory settings.
