1. indicated for use in the introduction of angiographic catheters, closed end catheters, balloon catheters, and electrodes into a vessel where minimizing blood loss is essential. 2. Material And Design : exclusive polymer, innovative design and advanced manufacturing technology to create the ultimate introducer for common catheterization procedures. 3. Kink resistance. 4. Access is gained with the less invasive taper configuration, while allowing for high flow. 5. Smooth transition between dilator and sheath. 6. provide outstanding insertion performance, with excellent wire-to-dilator and dilator-to-sheath transitions, high kink resistance and minimal wall thickness. 7. A dual layer sheath cannula provides optimal strength and flexibility, and works with an extra strong dilator to offer effortless introduction to the vessel. 8. valve design maintains hemostasis on guidewires..
