ABSTRACT:
A two part plastic catheterization device 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 rear of the device has a lumen for holding a catheter and the lumen is closed by a slidable cover member. The forward end of the lumen is terminated by a slanted guide wall and the forward end of the cover member is resiliently flexible to engage a recess in the guide wall to retain the cover member when it closes the lumen. This device eliminates the need for a separate guidewire and allows the use of a small diameter needle to minimize damage to the blood vessel wall. In an alternate embodiment, the cover member fills substantially the entire lumen and includes a longitudinal slot for holding a guidewire.
