The Boston Scientific MACH1 KR3S 7F Coronary Guiding Catheter (REF H749343576540) is a single-use guiding catheter designed to provide consistent backup support, smooth tracking and accurate torque transmission during percutaneous coronary interventions. The MACH1 platform features a stiff proximal shaft, a transition zone, and a softer distal segment with an atraumatic tip to facilitate coronary ostial engagement and device delivery.

Key Features
Single-piece extruded shaft construction engineered for 1:1 torque response.
Stainless steel braid reinforcement for kink resistance and pushability.
PTFE inner lumen to support smooth passage of interventional devices.
Soft, atraumatic distal tip designed to reduce vessel trauma during engagement.
KR3S preformed curve intended for right coronary artery cannulation with extra support.
7F outer diameter compatible with a wide range of interventional accessories.

Clinical Applications
Selective cannulation and contrast delivery in coronary angiography.
Conduit for guidewires, balloons, stents and other interventional devices during PCI.
Procedures requiring enhanced backup support in the right coronary system.
Use in cases where predictable curve retention and torque control are required.
