The Boston Scientific MACH1 LCB 90cm SH 8F Coronary Guiding Catheter (REF H749343584050) is a single-use interventional guiding catheter engineered to deliver predictable backup support, accurate torque response, and stable coaxial alignment during percutaneous coronary procedures. The Left Coronary Bypass (LCB) curve is shaped to facilitate selective engagement of left-sided saphenous vein grafts, while the Short Head (SH) tip configuration is intended to refine the depth of vessel engagement.

Key Features
Proprietary MACH1 shaft construction designed for high torque transmission and kink resistance.
Left Coronary Bypass (LCB) preformed curve for selective bypass graft access.
Short Head (SH) tip variant for adjusted engagement geometry.
8F outer diameter providing a large internal lumen to support interventional device delivery.
90 cm usable length suitable for standard femoral access workflows.
Lubricious inner lining intended to ease guidewire and device passage.
Atraumatic soft tip designed to reduce vessel trauma at the ostium.

Clinical Applications
Selective cannulation and contrast injection of left-sided coronary bypass grafts.
Support catheter for percutaneous coronary intervention (PCI) in graft anatomy.
Delivery conduit for balloons, stents, and adjunctive interventional devices compatible with an 8F lumen.
Diagnostic and interventional cases requiring stable coaxial backup in bypass graft procedures.
