An introducer for a catheter and a closed-end infusion catheter are provided. The catheter may be porous or may have a number of holes in which to infuse anesthetics into a body area of a patient. The introducer allows for introducing and proper placement of the catheter in the body of the patient. In addition, a method for using the introducer to place the catheter in the body of the patient is provided. The introducer may pierce the skin of the patient and may be inserted through the subcutaneous layer to an exit site. After a portion of the introducer protrudes through the exit site, the catheter may be attached to the introducer. The introducer may be pulled into the body, through the subcutaneous layer and out of the body at the original entry site. The introducer may then be removed, and the catheter may be pulled into place and sutured to the skin. <IMAGE>
