Tunica ablation
View Patent ↗In a method of ablating a tunica of a patient, a laser fiber is inserted into the tunica of the patient. Portions of the tunica are exposed to laser light discharged from the laser fiber. The portions of the tunica that are exposed to the laser light are ablated. In one embodiment, a device is used to control the exposure of the tunica to the laser light. In one embodiment, a penile prosthesis is implanted in the ablated tunica.
1. A method of selectively ablating portions of the tunica of the corpus cavernosa of a patient comprising:
inserting a laser fiber into the tunica of the patient
exposing portions of the tunica to laser light discharged from the laser fiber; and
ablating the portions of the tunica that are exposed to the laser light.
2. The method of claim 1 , wherein exposing portions of the tunica to laser light discharged from the laser fiber comprises:
discharging pulses of laser light from the laser fiber within the tunica; and
moving the laser fiber relative to the tunica along a longitudinal axis of the tunica;
wherein the ablated portions of the tunica are surrounded by non-ablated portions of the tunica.
3. The method of claim 2 , further comprising:
removing the laser fiber from the tunica following ablating the portions of the tunica; and
implanting a penile prosthesis in the tunica.
4. The method of claim 1 , wherein:
the method further comprises:
providing a device comprising a cylindrical tube comprising an open proximal end and a plurality of openings; and
inserting the tube into the tunica of the patient;
inserting a laser fiber into the tunica of the patient comprises inserting the laser fiber into the tube; and
exposing portions of the tunica to laser light discharged from the laser fiber comprises discharging laser light from the laser fiber through the openings in the tube to the portions of the tunica.
5. The method of claim 4 , wherein providing a device comprises providing a device comprising a handle attached to the proximal end.
6. The method of claim 4 , wherein exposing portions of the tunica to laser light discharged from the laser fiber comprises:
discharging laser light from the laser fiber within the tube and the tunica; and
moving the laser fiber along a central axis of the tube relative to the tube and the tunica.
7. The method of claim 6 , further comprising rotating the laser fiber about the central axis relative to the tube and the tunica during discharging laser light from the laser fiber.
8. The method of claim 4 , further comprising:
removing the laser fiber and the tube from the tunica following ablating the portions of the tunica; and
implanting a penile prosthesis in the tunica following removing the laser fiber and the tube from the tunica.
9. The method of claim 1 , further comprising treating Peyronie's disease in response to ablating the portions of the tunica that are exposed to the laser light.
