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 <IMAGE> |
