Intravascular access is achieved by introducing a catheter having a guide element recess that is placed to receive a contoured distal end of a guide element. The guide element may advance along the outer surface of the access needle to form a loop beyond the distal end of the needle. Once beyond the distal end of the needle, the deployed guide element may form a partial or complete loop. After the catheter has been properly positioned, the access needle and guide element may be removed by automatic withdrawal, leaving the catheter in place within the vessel and available for use. 通过引入具有引导元件凹陷的导管来实现血管内进入，该引导元件凹陷被放置以接收引导元件的带轮廓的远端。引导元件可以沿着进入针的外表面前进，以形成超过针远端的环。一旦超过针的远端，部署的引导元件可以形成部分或完整的环。在导管已经被正确定位之后，进入针和引导元件可以通过自动撤回来移除，将导管留在血管内的适当位置并可供使用。
