The Boston Scientific MACH1 JR4 SH 6F Coronary Guiding Catheter (REF H749343566920) is a single-use guiding catheter designed for selective cannulation of the coronary ostia and delivery of interventional devices during percutaneous coronary procedures. The MACH1 platform is engineered to provide a consistent shape, strong backup support, and a large, smooth inner lumen to facilitate device tracking and contrast delivery.

Key Features
Pre-shaped JR4 (Judkins Right 4) Short tip configuration intended for engagement of the right coronary ostium with a shorter reach geometry.
6 French outer diameter compatible with standard radial and femoral access workflows.
Stainless steel braided shaft designed for 1:1 torque response and kink resistance.
Large, polished inner lumen to support contrast injection and passage of interventional devices.
Atraumatic soft tip designed to reduce the risk of vessel trauma during ostial engagement.
Lubricious inner coating to facilitate smooth device delivery.
Single-use, sterile, packaged for procedural readiness.

Clinical Applications
Selective angiography and guiding support during percutaneous coronary intervention (PCI).
Engagement of the right coronary artery in anatomies suited to a short Judkins Right curve.
Delivery of guidewires, balloon catheters, stents, and other interventional devices to the coronary vasculature.
Use in diagnostic and interventional cardiac catheterization laboratory workflows.
