ABSTRACT:
A balloon catheter comprises a catheter shaft which typically defines a first inflation lumen and a first, inflatable balloon mounted on the shaft in communication with the first inflation lumen. By this invention a second inflation lumen is typically provided, spaced from the first lumen and defined by the catheter shaft. A second balloon is mounted on the shaft in communication with the second inflation lumen. The second balloon defines apertures which are sized to permit liquid flow outwardly through the balloon. Thus, medication may be delivered in a controlled manner. Alternatively, the second balloon for medication administration may be the only balloon present on the catheter.
