The Boston Scientific MACH1 LCB Coronary Guiding Catheter (REF H749343583830) is an 8F, 90 cm guiding catheter engineered to deliver consistent backup support, smooth torque transmission and reliable lumen integrity during percutaneous coronary interventions. The LCB (Left Coronary Bypass) curve is configured to facilitate engagement of left-sided coronary artery bypass graft anatomy.

Key Features
Pre-shaped LCB curve intended for left coronary bypass graft cannulation.
8F outer diameter providing a large inner lumen to accommodate complex interventional device combinations.
90 cm working length suited to standard femoral access PCI workflows.
Multi-layer shaft construction designed for kink resistance and 1:1 torque response.
Smooth atraumatic tip intended to reduce vessel trauma during engagement.
Hydrophilic-compatible outer surface to support tracking through tortuous anatomy.

Clinical Applications
Diagnostic and interventional access to left-sided coronary artery bypass grafts.
Delivery and exchange of guidewires, balloons, stents and other interventional devices during PCI.
Procedures requiring enhanced backup support from a large-lumen 8F platform.
Complex coronary cases including bifurcation, CTO support and multi-device strategies where lumen capacity is a priority.
