A method of making an epidural insertion of a catheter and means for retention therein whereby a double lumen catheter having an air and medication conduit are provided, and the air conduit has a retention balloon at the distal, epidural end and a pilot indicator balloon at the proximal end. The catheter is inserted through a stylet and the balloon is expanded. The stylet (needle) is withdrawn, the catheter temporarily fastened by external means, the balloons deflated, the needle removed, and the epidural balloon reinflated to hold the catheter in place.
