ABSTRACT:
An improved dilator/introducer used to facilitate the placement of a catheter within an internal area of a body. The introducer portion of the device has a tapered and bevelled forward end. The dilator portion of the device has a longitudinally extending slot located proximate its rearward end to provide a side exit point for a "J"-wire. Optionally, a plug also having a slot can be received within the rearward end of the dilator to provide an enlarged, smooth surface area that can receive pressure from the palm area of the inserter's hand.
