The Boston Scientific MACH1 Q3.5 SH 6F Coronary Guiding Catheter (REF H749343562970) is a single-use interventional guiding catheter engineered to provide predictable engagement and stable backup support during percutaneous coronary procedures. The MACH1 platform is designed to deliver a balance of pushability, torque response and lumen integrity to facilitate device delivery during diagnostic and therapeutic coronary interventions.

Key Features
- Curve: Q3.5 (Amplatz-style configuration) for targeted coronary ostial engagement.
- Tip configuration: SH (Short) tip variant.
- Outer diameter: 6F.
- Construction: Multi-layer shaft design intended to combine kink resistance with torque transmission.
- Inner lumen: Lubricious PTFE inner liner intended to support smooth device passage.
- Atraumatic soft tip intended to reduce vessel trauma at the ostium.
- Radiopaque marker for fluoroscopic visualization.
- Usable length: Not specified in the located sources.
- Maximum guidewire compatibility: Not specified in the located sources.
- Sterile, single-use device.

Clinical Applications
- Selective cannulation of the coronary ostia during percutaneous coronary intervention (PCI).
- Delivery of interventional devices such as guidewires, balloon catheters and stent delivery systems into the coronary vasculature.
- Procedures requiring an Amplatz-style curve geometry for backup support, including selected left and right coronary anatomies as determined by the operator.
- Use should be in accordance with the manufacturer Instructions for Use and by trained interventional cardiology personnel.
