The Boston Scientific MACH1 VL4 7F Coronary Guiding Catheter (REF H74934357730) is a single-use coronary guiding catheter designed to provide consistent backup support, torque transmission and lumen integrity during percutaneous coronary interventions. The MACH1 platform combines a stiff proximal shaft with a softer atraumatic distal tip to facilitate ostial engagement and device delivery.

Key Features
Three-layer shaft construction engineered for 1:1 torque response and kink resistance.
Stainless steel braid reinforcement supporting lumen patency under load.
VL4 (Voda Left 4) curve geometry intended for left coronary artery cannulation with extra backup support.
7F outer diameter compatible with standard 7F-capable interventional accessories.
Soft, tapered atraumatic distal tip designed to reduce vessel trauma at engagement.
PTFE inner lumen liner to support smooth device tracking and delivery.
Sterile, single-use configuration.

Clinical Applications
Introduction of interventional devices into the coronary vasculature.
Left coronary artery engagement requiring enhanced backup support via a Voda-style curve.
Complex PCI workflows where 7F lumen capacity is needed for multi-device or larger-profile equipment.
Diagnostic and therapeutic catheterization laboratory procedures performed by trained interventional cardiologists.
