The Boston Scientific MACH1 KR4S 6F Coronary Guiding Catheter (REF H749343566550) is a single-use interventional catheter engineered to deliver predictable backup support, accurate tip placement and smooth device tracking during percutaneous coronary procedures. The MACH1 platform is built around a proprietary three-layer shaft construction intended to combine kink resistance with responsive 1:1 torque transmission.

Key Features
- 6F outer diameter compatible with standard radial and femoral access workflows.
- KR4S curve geometry shaped to engage the right coronary ostium with extra backup support.
- Three-layer shaft construction designed for kink resistance and 1:1 torque response.
- Large, smooth inner lumen intended to facilitate device delivery and contrast injection.
- Atraumatic soft tip designed to reduce the risk of vessel trauma during engagement.
- Hydrophilic outer coating to support smooth advancement through the vasculature.

Clinical Applications
- Percutaneous coronary intervention (PCI) requiring guiding catheter support.
- Selective engagement and contrast delivery to the coronary ostium.
- Delivery of guidewires, balloon catheters, stents and other interventional devices to target coronary lesions.
- Procedures where enhanced backup support of the right coronary system is preferred.
