Abstract
A pain management system for the infusion of drug to a wound site includes a pump connected to medical tubing which is connected to an improved infusion catheter for providing uniform delivery of fluid throughout an anatomical region. One method by which the infusion catheter is advanced to the wound site includes a guide needle that is placed within an introducer tubing. The needle is pierced through the patient's skin, after which the guide needle is withdrawn and discarded, leaving the introducer tubing in place partially under the patient's skin. The infusion catheter is then threaded through the introducer tubing and advanced to the wound site. The introducer tubing is then withdrawn and the infusion catheter remains in place to provide drug to the wound site. The introducer tubing is preferably peeled off of the infusion catheter and discarded. In accordance with one embodiment of the catheter, the catheter comprises an elongated tube with a plurality of exit holes along an infusion section of the catheter, and an elongated flexible porous member residing within the tube and forming an annular space between the tube and the member.
