Preferably the lumina have different cross sectional areas.

The larger of the two lumina should preferably be of sufficient size to allow an epidural catheter, spinal needle or guide wire to be introduced. The needle of the present invention has applications of regional anesthesia, chronic and post operative pain management, cricothyroid puncture, intracerebroventricular puncture and, access and drainage of concealed fluid collections within the body.
