The Boston Scientific MACH1 KR3S SH 6F Coronary Guiding Catheter (REF H749343566570) is a single-use interventional guiding catheter designed to deliver consistent backup support, accurate tip placement and stable torque response during percutaneous coronary procedures. The MACH1 platform is engineered to provide a balance of pushability, kink resistance and lumen integrity to facilitate device delivery to the target coronary anatomy.

Key Features
- MACH1 catheter construction engineered for high torque transmission and 1:1 response
- KR3S curve geometry intended to provide enhanced backup support for selective coronary cannulation
- SH (Side Hole) configuration to support coronary perfusion during deep engagement
- 6F outer diameter compatible with standard radial and femoral access workflows
- Smooth inner lumen designed to facilitate passage of interventional devices
- Atraumatic soft tip designed to reduce vessel trauma during engagement
- Single-use, sterile packaged device

Clinical Applications
- Diagnostic and interventional coronary catheterization procedures
- Delivery and exchange of guidewires, balloons, stents and other interventional devices to the coronary arteries
- Procedures requiring stable backup support with the option of side-hole perfusion
Use is restricted to trained interventional clinicians in accordance with the official Instructions for Use.
