The Boston Scientific MACH1 KR3H 8F Coronary Guiding Catheter (REF H749343586480) is a single-use guiding catheter from the MACH1 family, designed to provide consistent coronary ostial engagement and reliable backup support during percutaneous coronary procedures. The KR3H curve is intended for right coronary access with extra back-up support, while the 8F outer diameter accommodates the passage of interventional devices through the catheter lumen.

Key Features
Single-piece, full-length braided shaft engineered for 1:1 torque response and pushability.
KR3H curve geometry intended to facilitate cannulation of the right coronary ostium with enhanced back-up support.
8F outer diameter sized to accommodate a broad range of coronary interventional devices.
Smooth inner lumen designed to support consistent device tracking and contrast delivery.
Atraumatic soft tip designed to reduce the potential for vessel trauma during engagement.
Hydrophilic or lubricious coating profile as specified by the manufacturer for the MACH1 family.

Clinical Applications
Introduction and support of interventional cardiology devices into the coronary vasculature.
Use in percutaneous coronary intervention (PCI) cases requiring extra back-up support from the right coronary system.
Delivery of contrast media and compatible therapeutic or diagnostic devices to a target coronary site.
