Dilating device and method for prostatic urethra

A method for dilating a prostatic urethra of a patient comprising:

• Inserting a dilating device into the prostatic urethra of the patient said dilating device including a first elongated edge member having a first distally protruding nose portion and second elongated edge member having a second distally protruding nose portion symmetrically opposing each other across a spinal longitudinal axis, said first distally protruding nose portion and said second distally protruding nose portions protruding distally from the dilating device;
• aligning the first elongated edge member and the second elongated edge member with posterolateral interlobar grooves of the prostatic urethra;
• positioning said first distally protruding nose portion and said second distally protruding nose portion of the dilating device within the prostatic urethra on opposite lateral sides of a posterior portion thereof proximal to a bladder neck,
• stretching laterally posterolateral sides of the prostatic urethra adjacent to the bladder neck with said first distally protruding nose portion and said second distally protruding nose portion;
• preventing migration of the dilating device into a urinary bladder of the patient via said positioning and said stretching;
• expanding said dilating device to an open configuration within said prostatic urethra and
• exerting a radially outwards force on the prostatic urethra with said expanded dilating device to dilate the prostatic urethra.
