A medical device includes a catheter having a proximal end and a distal end, the catheter defining a lumen. A passage for a guide wire is disposed within the lumen so as to be coaxial with the lumen. The passage has an open proximal end that is substantially coterminous with the proximal end of the catheter and an open distal end that is substantially coterminous with the distal end of the catheter. A fluid injection tube may be wound around the passage for the guide wire and may be provided with radially spaced fluid injection ports.
