The Boston Scientific MACH1 KR3H 7F Coronary Guiding Catheter (REF H749343576480) is a single-use interventional guiding catheter designed to deliver coronary devices to the target vessel while providing stable backup support. The MACH1 platform is engineered for consistent torque response, lumen integrity under pressure, and reliable ostial engagement across a range of anatomies.

Key Features
Full-length braided shaft construction intended to support 1:1 torque transmission and kink resistance.
KR3H curve geometry within the MACH1 family for shaped backup support during selective coronary cannulation.
7F outer diameter sizing to accommodate larger or multiple interventional devices through a single guide.
Smooth inner lumen designed to facilitate device tracking and contrast delivery.
Atraumatic soft tip intended to reduce the risk of vessel trauma during engagement.
Radiopaque marker characteristics: Not specified in the located sources.

Clinical Applications
Intended for use in percutaneous coronary procedures requiring introduction of interventional devices into the coronary vasculature.
Supports diagnostic and interventional workflows where stable guide support and predictable curve behavior are required.
Specific approved indications, contraindications, and access route suitability should be confirmed against the current Boston Scientific Instructions for Use.
