21. A tissue dissecting implant kit, comprising:
-
an implant comprising a plurality of rings coupled to each other elastically, such that an elastic pressure is applied on tissue caught between adjacent rings; and
a sterile package encompassing the implant, wherein the implant has different distances between adjacent rings along its length or has different material thicknesses or cross-section shapes along its length. - View Dependent Claims (22, 23, 24, 25)

26. A tissue dissecting implant kit, comprising:
-
an elongate tube, sized and shaped to fit into a urethra, having a plurality of slits in a circumference of the tube, such that when the tube is in a stretched state along its length it applies a contraction force on tissue within the slits; and
a sterile package in which the tube is packaged. - View Dependent Claims (27)

34. A method of treating the urethra, comprising:
-
inserting to the urethra an outer tube;
inserting within the outer tube a viewing apparatus;
setting a position of the outer tube in the urethra, which position protects the sphincter, using the viewing apparatus; and
applying a treatment to the urethra while the sphincter is protected by the outer tube. - View Dependent Claims (35, 36, 37, 38, 39)

55. A method of implanting an implant into the urethra, comprising:
-
mounting the implant in a stretched state onto a probe suitable for insertion into the urethra;
inserting the probe into the urethra, with the implant in the axially stretched state; and
releasing the implant from the probe within the urethra, such that the implant axially condenses. - View Dependent Claims (56, 57, 58, 59)
