ABSTRACT:
A plastic device for inserting a catheter or the like into a body, wherein the forward end of the device acts as a dilator and has an offset axial opening along one side for a relatively small needle to pass through. The main portion of the device has a lumen for holding a catheter or the like. The forward end of the lumen is terminated by a slanted guide wall. The device eliminates the need for a separate guidewire and allows the use of a small diameter needle to minimize damage to the body wall.
