The Boston Scientific MACH1 CLS4 SH 6F Coronary Guiding Catheter (REF H749343565790) is a single-use guiding catheter from the MACH1 platform, designed to deliver consistent backup support and high torque transmission during diagnostic and interventional coronary procedures. The CLS4 SH curve is a Short-tip variant of the Contralateral Left Support family, intended to engage the left coronary system with stable seating in challenging anatomies.

Key Features
Single-piece full-length braided shaft engineered for 1:1 torque response and kink resistance.
Large round inner lumen optimized for device delivery and contrast flow at 6F.
CLS4 Short-tip curve geometry intended to provide enhanced backup support for the left coronary system.
Atraumatic soft tip designed to reduce the risk of vessel trauma during engagement.
Hydrophilic or lubricious outer coating to facilitate navigation through tortuous vasculature.
Radiopaque marker and shaft construction to support fluoroscopic visualization.

Clinical Applications
Introduction and support of interventional devices into the coronary vasculature.
Percutaneous coronary intervention (PCI) procedures requiring stable left coronary engagement.
Cases benefiting from contralateral wall support, including complex or calcified left-sided lesions.
Delivery of contrast media and compatible interventional accessories during catheterization.
