The catheter has an elongate tubular body with an elongate central lumen defined therein. The catheter also includes at least one occlusive balloon disposed on the exterior of and about the tubular body, and a drug delivery lumen defined within the tubular body separately of the central lumen and extending in the lengthwise direction of the tubular body. A drug delivery outlet is defined at and in communication with a distal end of the drug delivery lumen for permitting the delivery of fluids passed through the drug delivery lumen separate of any fluids passed through the central lumen of the catheter. A separate drug infusion port, in fluid communication with the drug delivery lumen, is provided at a proximal end of the catheter so that any desired fluids and/or medicines may be passed into the patient through the drug delivery lumen separately of the central lumen. The catheter may also include a pressure sensor at the distal end of the tubular body for measuring the pressure of fluid thereat during catheterization and/or fluid delivery therethrough.
