Dilating device and method for prostatic urethra

A method of expanding a prostatic urethra comprising:

• supplying an implant for the prostatic urethra the implant including a distal retractor including two distal protrusions connected by a connecting member and a proximal retractor;
• collapsing said implant by applying a laterally inward force on said distal protrusions to bend said connecting member;
• inserting said implant in a collapsed state into the prostatic urethra;
• orienting said implant in the prostatic urethra with said distal retractor cranial to said proximal retractor;
• further orienting said implant with said connecting member toward an anterior side of the prostatic urethra with relation to said distal protrusions oriented towards a posterior side of the prostatic urethra;
• positioning said distal protrusions within the prostatic urethra proximal to a bladder neck thereof;
• releasing said laterally inward force expanding said distal protrusions laterally and said connecting member anteriorly within a cranial portion of the prostatic urethra, said distal protrusions on opposite posterior-lateral sides of said bladder neck;
• expanding lateral walls of a cranial portion of the prostatic urethra adjacent to the bladder neck;
• resting said distal protrusions on a cranial side of said bladder neck to prevent migration of said implant into a urinary bladder;
• and
• opening said proximal retractor to support and expand lateral walls of a caudal portion of said prostatic urethra caudal to said cranial portion.
