1. A catheter and introducer needle assembly, comprising:
- a catheter having a proximal end and a distal end;
a catheter hub in fluid communication with the catheter and having a proximal end and a distal end connected to the proximal end of the catheter, the catheter hub including a radially extending wing and a side port in fluid communication with the catheter hub;
an elastomeric plug affixed to the catheter hub and located proximal of the side port;
an introducer needle having a proximal end and a distal end disposed inside the catheter; and
a needle hub having a proximal end and a distal end connected to the proximal end of needle, the needle hub defining a radially extending fin.

Abstract
The catheter includes a catheter hub at its proximal end having a radially extending wing. The needle is connected at its proximal end to a needle hub. The needle may have at least one notch therein. The needle hub defines a radially extending fin thereon. When the introducer needle is inserted through the catheter such that the distal tip of the needle extends beyond the distal tip of the catheter, the fin on the needle hub extends beyond the distal end of the wing on the catheter hub. This arrangement allows the distal tip of the needle to be retracted into the catheter with a simple proximal motion by the healthcare worker.
