Vasodilator sheath

1. Establishing Vascular Access: Dilates blood vessels, providing a pathway for interventional devices and ensuring smooth passage.

2. Ensuring Smooth Procedure: The inner PTFE layer reduces friction, the spring tube enhances support and flexibility, the outer Pebax layer improves biocompatibility and durability, and the injection-molded head reduces damage to the vessel wall, making it suitable for minimally invasive procedures.

This vascular dilation sheath, with its inner PTFE layer for lubrication, middle spring tube for structural reinforcement, outer Pebax layer for human adaptation, and injection-molded head, is a core access device for vascular interventional surgery.
