Abstract
A device for dilating at least an obstructed portion of the urethra, includes a urinary catheter having a proximal portion and a distal portion; a dilation balloon capable of expanding radially outwardly disposed between the proximal and distal portion of the catheter; and a pressure source capable of sequentially contracting under pressure. The pressure source and dilation balloon are in fluid communication through a conduit which enables fluid to flow from the pressure source to the dilation balloon at a predetermined gradual rate when the pressure source is contracting, whereby the balloon expands gradually radially outwardly to effect the slow dilation of the urethra. A method for dilating the obstructed portion of the urethra and for treating prostatic hyperplasia is also provided.
