Abstract
This invention provides a non-kinking and thin-walled introducer sheath (10) having a flat wire metal coil (12) that lies within a plastic covering (20) fitted onto the exterior surface of the flat wire metal coil (12) and extends into a space between adjacent turns of the flat wire metal coil (12) without covering the interior surface. Each turn of the flat wire metal coil (12) has a thickness within the range between 0.75-3.0 mils with a width to thickness ratio lying between 12 and 80. A plastic adapter (30) is provided and is located at a proximal end of the sheath (10) for inserting guide wires through the sheath (10) into a vessel.
