Abstract
A direct vision prostate balloon catheter for treating benign prostate hyperplasia to dilate a prostate gland to reduce constriction of the urethra is provided. The catheter includes an expandable balloon and a sighting device such as a cystoscope telescopic lens proximal to the veru montanum to assist in properly positioning the expandable member. The balloon can have a thickened distal end and an overlapping proximal end to prevent undesirable migration during expansion. Alternatively, the balloon can be mounted on two tubes, one slidable axially inside the other to control balloon extension during expansion of the balloon. This construction provides advantages such as proper dilation of the prostatic urethra and helps prevent undesirable dilation of the external sphincter.
