Radial cutter implant
An implant for creating incisions in the tissues surrounding the bladder neck and the urethra of a patient, for relaxing the opening of the bladder, the implant includes a central connector and at least one wire, the wires extend radially outwardly from the center of the central connector, the wires apply continuous pressure on the surrounding tissues, the wires are foldable within an implant sheath for enabling delivery and extraction thereof, the implant is implanted within a restricted location of the urethra for a period of time for creating incisions at the locations where the wires apply pressure on the surrounding tissues.
1. A method for extending a urinal passage by inducing infarction via application of continuous radial pressure on at least one of a urethral wall and tissue surrounding the urethral wall, the method comprising the procedures of:
delivering a removable implant to a vicinity of at least one of a bladder neck of a bladder and a prostatic urethra, said removable implant having at least one foldable wire and at least one anchor capable of self-expanding;
releasing said removable implant such that both said at least one foldable wire and said at least one anchor expand to prevent movement of said removable implant along said urethral wall in a direction toward said bladder;
applying said continuous pressure by said removable implant, thereby creating a plurality of longitudinal incisions in said urethral wall and in said tissue surrounding the urethral wall in a radial direction from a urethral axis outwardly; and
at the appearance of a predetermined condition, extracting said removable implant.
2. The method of claim 1 , further comprising a procedure of finding the location of at least one of said bladder neck and said prostatic urethra, performed before said procedure of delivering.
