Abstract
An apparatus for dilation of the prostate urethra comprises a urinary catheter for insertion in the prostate urethra, dilation means mounted on the proximal section of the catheter and in communication with the interior of the catheter, location means mounted axially on the catheter at a distance from the dilation means such that the location means is at the bulbous urethra when the dilation means is at the prostate urethra, and activating means for activating said dilation means and said location means. A method for the treatment of benign prostatic hyperplasia comprises inserting a urinary catheter having dilation means and location means and removing the catheter after dilation.
Claims15
An apparatus for dilation of the prostate urethra comprising:
- a urinary catheter for insertion in the prostate urethra, said catheter having a proximal section and a distal section;
- dilation means mounted on said proximal section of the catheter for dilating the prostate urethra;
- location means mounted on the catheter at a distance from the dilation means such that the location means is positioned at and fits in the bulbous urethra distal from the external sphincter when the dilation means is positioned at the prostate urethral;
- and
- activating means located at said distal section of the catheter for activating said dilation means and said location means, and thereby holding the catheter in place when said dilation means and said location means are activated.
A method for the treatment of benign prostatic hyperplasia which comprises:
- inserting into a prostate urethra a hollow, impervious, urinary catheter having dilation means for dilating the prostate urethra and location means for locating the dilation means at the prostate urethra;
- locating and fixing said location means;
- placing and dilating said dilation means and thereby dilating the prostate urethra with said dilation means to alleviate obstruction of the prostate urethra resulting from benign prostatic hyperplasia;
- deactivating said dilation means and location means, and removing said catheter from said prostate urethra.
