Abstract
A catheter assembly comprises a stylus including a first generally conically shaped end tapering to a point at a predetermined angle and a second end. A cannula includes a first lumen for slidably receiving the stylus. The cannula includes a first end having an end wall and a second end. A catheter includes a second lumen for slidably receiving the cannula, a first end and a second end. The first end of the catheter includes an end wall having an outer surface tapered at the predetermined angle and an inner surface. The stylus, cannula, and catheter are configured so that the stylus, cannula, and catheter are aligned when the stylus, cannula and catheter are assembled for insertion into a patient's body. The first end of the stylus projects from the first end of the cannula, the tapered outer surface of the end wall of the catheter is aligned to be substantially coincident with the generally conically shaped end of the stylus to form a generally conical tip portion of the catheter assembly, and the end wall of the cannula abuts the inner surface of the end wall of the catheter to facilitate insertion of the catheter assembly into the patient's body.
