Abstract
A balloon catheter comprises a catheter shaft, and first and second balloons carried on the catheter shaft with the second balloon positioned to at least partly overlie and sealingly enclose the first balloon. A lumen is defined by the catheter shaft to communicate between a space located within the first balloon and a proximal end portion of the catheter shaft. The first and second balloons each define holes of a size to permit medication delivered through the lumen to pass outwardly through the perforations of both the first and second balloons. By such an arrangement, medication may be directly delivered over a wide area to tissue without tissue damage.
