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. The infusion catheter is inserted into the body of a patient at a pierce site, spaced from an incision site, and extended to the wound site. The pump causes the drug to flow through the medical tubing, through the infusion catheter and to the wound site. 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 The needle is pierced through the patient's skin, after which the guide needle is withdrawn and discarded, leaving the introducer tubing in place partially under the patient's skin.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.

Abstract: A device for regulating the flow rate of a fluid includes a housing containing a plurality of flow conduits fluidly connecting an inlet and an outlet, each of the flow conduits comprising a flow control tube (310, 312, 314) and a resiliently compressive occlusion tube (316, 318, 320), wherein the flow control tubes are of substantially equal internal diameter. Each of the flow control tubes has a length associated with a different flow rate. A resilient flow-blocking element (212a, 212b, 212c) is operatively associated with each of the occlusion tubes and is movable into a flow-blocking compression against its associated occlusion tube. An actuation mechanism (206) in the housing is operable: (a) to selectively engage and move one or more of the flow-blocking elements into the flow-blocking compression against its associated occlusion tube, and (b) to selectively be disengaged from any of the flow-blocking elements.
