A system for delivering an anaesthetic-containing fluid to a desired site in a patient includes a catheter for channeling the fluid into a unitary portal penetrating a body. A pump capable of delivering fluid at a constant flow rate is dimensioned to retain sufficient fluid for at least a one-day delivery and is adapted to permit being affixed to the body to permit portability. A fluid line, such as tubing, transports fluid from the pump to the catheter. A kit further includes an introducer needle dimensioned to permit the catheter to pass therethrough. A method of relieving pain at a surgical site postoperatively over an extended period of time includes the steps of inserting an anaesthetic-containing fluid into a pump interior having a capacity sufficient for at least a two-day delivery. The skin of a patient is punctured with an introducer needle at a desired site adjacent the surgical site, and an epidural-type catheter is passed through the introducer needle, which is then removed, leaving the catheter at the desired site. The catheter connects tubing to the pump interior, and fluid is permitted to flow from the pump to the desired site.
