The present invention provides a catheter which combines the benefits of improved drug dispersion, increased accuracy of placement and kink and collapse resistance. The catheter comprises a flexible cylindrical tube having a proximal portion open at one end and a distal portion, the portions in fluid communication, the distal portion comprising a closed, rounded tip and a diffusion area having at least one opening therein which permits fluid flow, the proximal portion including a proximal tip, and at least one reinforcement member attached at the distal tip and at the proximal tip of the flexible cylindrical tube, with the remainder of the at least one reinforcement member movable within the flexible cylindrical tube. The catheters of the present invention can find use in a variety of local, regional and peripheral pain management applications.
