The Boston Scientific MACH1 FL3.5 SH 8F Coronary Guiding Catheter (REF H74934358520) is a single-use interventional guiding catheter designed to deliver interventional devices into the coronary vasculature. The MACH1 platform combines a stiff proximal shaft with a softer atraumatic distal segment to provide stable backup support, accurate tip placement and efficient transmission of push and torque during diagnostic and therapeutic coronary procedures.

Key Features
Stiff proximal shaft engineered for high push and torque transmission.
Soft, atraumatic distal tip designed to reduce vessel trauma at engagement.
FL3.5 (Left Femoral) curve geometry for engagement of the left coronary ostium.
SH (Side Hole) configuration to support coronary perfusion during deep engagement.
8F outer diameter providing a large inner lumen for multi-device or bulky interventional equipment.
Lubricious inner lumen to facilitate device delivery and minimize friction.
Radiopaque tip marker for clear fluoroscopic visualization.
Single-use, sterile packaging consistent with interventional cardiology workflows.

Clinical Applications
Percutaneous coronary intervention (PCI) requiring stable left coronary engagement.
Complex interventions where larger lumen access is preferred, such as bifurcation, rotational atherectomy or two-stent strategies.
Procedures where side holes are desired to maintain coronary flow during deep cannulation.
Femoral access cardiac catheterization workflows.
