Abstract

An incising implant creates incisions in the prostatic urethra of a subject. The implant includes at least two closed-shaped wires, each of the wires having a proximal section, a distal section and two lateral sections extending between the proximal section and the distal section. Each of the closed-shaped wires is elastic thereby being compressible into a compressed configuration. Each of the lateral sections of each of the wires is adjoined with another lateral section of another one of the wires.

Claims

1. Incising implant for creating incisions in the prostatic urethra of a subject, the implant comprising:

at least two closed-shaped wires, each of said wires having a proximal section, a distal section and two lateral sections extending between said proximal section and said distal section, each of said closed-shaped wires being elastic thereby being compressible into a compressed configuration, each of said lateral sections of each of said wires being adjoined with another lateral section of another one of said wires.

2. The incising implant of claim 1, wherein each of said lateral sections of each of said wires being wound around said another lateral section of said another one of said wires.

3. The incising implant of claim 1, further comprising a proximal cap coupled with said proximal section of each of said wires, said proximal cap configured to hold said wires together.

4. The incising implant of claim 3, wherein said proximal cap including a proximal non-round niche configured to accept a corresponding pin, and configured to transfer rotary motion of said pin to said incising implant.

5. The incising implant of claim 1, wherein an extraction string is coupled with said incising implant and being arranged to allow pulling said incising implant out of said subject.

7. The incising implant of claim 1, wherein said wires form together a wire frame having a proximal apex formed by said proximal section of each of said wires, and having a distal base formed by said distal ends of each of said wires.

8. The incising implant of claim 1, further composing an anchoring leaflet for preventing said incising implant from moving in the direction of extension of said anchoring leaflet.

9. The implanting method of claim 8, further comprising the procedure of rotating said implant into a desired rotary stance, said procedure of rotating being performed after said procedure of pushing said incising implant and before said procedure of pulling said incising implant.

10. The implanting method of claim 8, wherein said incising implant remains implanted for at least one day.

11. The implanting method of claim 8, further comprising the procedure of extracting said incising implant by inserting an extraction sheath into said urethra, enfolding said incising implant within said extraction sheath, and pulling said extraction sheath and said incising implant out of said subject.

8-1. A method for implanting an incising implant within a prostatic urethra of a subject, said method comprising the following procedures:

enfolding said incising implant within a sheath thereby compressing said incising implant such that said incising implant conforms to a diameter of said sheath, said incising implant being elastic;

inserting said sheath into a urethra of said subject until a distal end of said sheath extends into a bladder of said subject;

pushing said incising implant within said sheath until said incising implant exits said distal end of said sheath; and

pulling said incising implant until said incising implant being implanted within said prostatic urethra.
