1. A catheter introducer, comprising:
- an introducer cannula having a proximal portion, an open proximal end, an open distal end, a lumen extending between the open proximal end and the open distal end;
a pair of wings connected along the proximal portion of the introducer cannula;
a tray, with an open top, extending from the open proximal end of the introducer cannula between the pair of wings;
an introducer needle disposed in the lumen of the introducer cannula and defining an annular space with the introducer cannula, the introducer needle having a sharp distal tip, a proximal end, a longitudinal axis and a needle lumen extending between the sharp distal tip and the proximal end wherein the introducer needle defines a notch to provide fluid communication between the needle lumen and the annular space; and
a needle hub with a center of mass connected to the proximal end of the introducer needle.

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.

5. A catheter introducer, comprising:
-
an introducer cannula having a proximal portion, an open proximal end, an open distal end, a lumen extending between the open proximal end and the open distal end, a longitudinal axis and a radius;
a pair of wings having a center of mass connected along the proximal portion of the introducer cannula such that the center of mass is offset from the longitudinal axis of the introducer cannula;
a tray, with an open top, extending from the open proximal end of the introducer cannula between the pair of wings;
