The Boston Scientific MACH1 Q3.5 6F Coronary Guiding Catheter (REF H749343562930) is a single-use guiding catheter designed for use during diagnostic and interventional coronary procedures. The MACH1 platform combines a stiff proximal shaft with a softer atraumatic distal segment to deliver predictable backup support, accurate 1:1 torque transmission and a stable working lumen for device delivery.

Key Features
Q3.5 curve geometry intended for selective engagement of coronary ostia.
6F outer diameter compatible with standard radial and femoral access workflows.
Three-layer shaft construction with stainless steel braid for kink resistance and torque response.
Soft, atraumatic radiopaque tip designed to reduce the risk of vessel trauma during engagement.
Lubricious inner lumen to support smooth passage of interventional devices.
Full-length hydrophilic or PTFE-lined inner surface (per manufacturer specifications) to facilitate device tracking.

Clinical Applications
Intended for the introduction of interventional and diagnostic devices into the coronary vasculature.
Supports balloon catheters, stents, guidewires and adjunctive PCI devices.
Q3.5 curve commonly considered for selective coronary cannulation where a Q-style backup support shape is preferred by the operator.
Use is at the discretion of the trained interventional cardiologist based on patient anatomy and procedural requirements.
