The guiding catheter is a sophisticated medical device designed to facilitate interventional procedures by providing a reliable access point for various tools such as balloon catheters, guidewires, and therapeutic devices. Key features of this product include a nylon shaft with a frictionless outer surface that helps prevent thrombus formation, a soft tip to minimize potential vessel injury, and radiopaque marker bands for improved visibility under imaging. The coaxial segments offer exceptional torsion control and maneuverability, while the 304V stainless steel braiding with a reduced pitch size ensures robust support and resistance to kinking. The large lumen design maximizes the flow of contrast media and enhances compatibility with different devices. Additionally, the PTFE inner tube design provides superior pushability during the delivery of support devices. An 18mm flexible distal segment ensures a seamless transition between the distal and proximal ends, contributing to excellent steerability and torque control throughout the procedure. Overall, this guiding catheter is engineered to deliver precision, safety, and efficiency in complex cardiovascular interventions.
