2. The removable urethral implant of claim 1 , wherein each one of said at least two wires is configured to self-expand, once exposed from an implant sheath.

3. The removable urethral implant of claim 2 , wherein at least part of said removable urethral implant is enabled to be folded within said implant sheath in said folded configuration.

4. The removable urethral implant of claim 1 , wherein a time period during which said removable urethral implant is implanted is selected from a list consisting of:

determined in real time according to observations;

predetermined; and

between one hour and 29 days.

5. The removable urethral implant of claim 1 , wherein said proximal end is tapered.

6. The removable urethral implant of claim 1 , wherein a shape of each one of said at least two wires is selected from the list consisting of:

wider at said proximal end than at said distal end thereof for preventing said removable urethral implant from moving in the distal direction;

wider at said distal end than at said proximal end thereof for preventing said removable urethral implant from moving in the proximal direction; and

narrower at the middle thereof than at said distal end and said proximal end for preventing said removable urethral implant from moving in said proximal direction and in said distal direction.

7. The removable urethral implant of claim 1 , wherein said at least one anchor is configured for preventing said removable urethral implant from moving in the direction of extension of said at least one anchor.

8. The removable urethral implant of claim 1 , wherein said removable urethral implant is made from biodegradable materials.

9. The removable urethral implant of claim 1 , further comprising a substance release element, the release element being configured to slowly release substances into a body of an implantee, wherein said substances are selected from the list consisting of:

anti-inflammatory;

anti-biotics; and

painkillers.

10. The removable urethral implant of claim 1 , wherein said at least one anchor comprises two anchors including a first anchor extending in a proximal-normal direction; and a second anchor extending in a distal-normal direction.

11. The removable urethral implant of claim 1 , wherein said narrower portion is configured for implanting within a bladder neck, and said wider portion is configured for positioning within a bladder.

12. The removable urethral implant of claim 11 , wherein said wider portion is configured to prevent said removable urethral implant from moving away from said bladder along a urethra.

13. The removable urethral implant of claim 11 , wherein said at least one anchor is configured to anchor at said bladder neck to prevent said removable urethral implant from moving along a urethra in a direction toward said bladder.

14. The removable urethral implant of claim 1 , wherein said at least two wires are configured to induce infarction via application of continuous radial pressure on at least one of a urethral wall and tissue surrounding the urethral wall.

15. The removable urethral implant of claim 1 , wherein said at least two wires are configured to apply pressure on tissues of at least one of a urethra and a prostate gland, and wherein said at least two wires are configured to create incisions in said tissues.

16. A removable urethral implant for extending a urinal passage, the removable urethral implant comprising:

a central connector having a distal end and a proximal end;

at least one wire extending along said central connector between said distal end and said proximal end, the at least one wire coupled with said central connector at said distal end and at said proximal end, said at least one wire converges with said central connector and arcs between said proximal end and at said distal end in an expanded configuration of said removable urethral implant; and

at least one anchor coupled to said at least one wire, said at least one anchor being capable of expanding and configured for anchoring said removable urethral implant;

wherein said at least one wire is foldable in a folded configuration of said removable urethral implant for enabling delivery and extraction of said removable urethral implant, wherein said central connector is a tube enabling urine flow therethrough, and wherein said removable urethral implant is only configured to be implanted within a urethra.

17. The removable urethral implant of claim 16 , wherein said at least one wire is configured to induce infarction via application of continuous radial pressure on at least one of a urethral wall and tissue surrounding the urethral wall.

18. The removable urethral implant of claim 16 , wherein said at least one anchor is configured to anchor at a bladder neck of a patient to prevent said removable urethral implant from moving along a urethra in a direction toward a bladder of said patient.

19. The removable urethral implant of claim 16 , further comprising wing elements for preventing tissue from growing around said at least one wire.

20. The removable urethral implant of claim 16 , wherein said at least one wire is configured to apply pressure on tissues of at least one of a urethra and a prostate gland, and wherein said at least one wire is configured to create incisions in said tissues.

21. A removable urethral implant for extending a urinal passage; the removable urethral implant comprising:

at least two wires extending between a distal end and a proximal end of said removable urethral implant, said distal end and said proximal end are termini of said removable urethral implant, each wire includes a wider portion extending between said proximal end and an intermediate portion of said wire, and a narrower portion extending between said intermediate portion and said distal end, said at least two wires converge at said proximal end and at said distal end in an expanded configuration of said removable urethral implant; and

at least one anchor having two ends, the two ends being linked to form a closed loop, both of said two ends being coupled to one of said distal end and said proximal end, said at least one anchor configured to extend radially outwardly to be positioned in said expanded configuration;
