Abstract
A catheter is provided having a larger size than the cannula through which it is introduced into a puncture site, such as a vein. The oversized catheter is preferably elliptical shaped, and, prior to introduction into the cannula, the catheter is folded to reduce its overall cross sectional area. The catheter is then advanced through the smaller cannula either manually, or by advancing roller drives, and then inserted into the patient. Use of an oversized catheter reduces the possibility of it slipping out from a vein, and its elliptical configuration is useful in conforming to a vein shape for improved retention therein and laminar blood flow.
