Abstract
A catheter introducer is disclosed having a splittable introducer and an introducer needle. The splittable introducer includes a pair of wings and a tray with an open top extending from the proximal end of the introducer cannula between the wings to lead the distal end of a long, thin and flexible medical device into the open proximal end of the splittable introducer cannula.
