Methods and systems for the treatment of polycystic ovary syndrome
Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may be useful in the treatment of infertility associated with PCOS.
1. A method for treating infertility associated with polycystic ovary syndrome in a patient in need thereof, the method comprising:
advancing a docking device toward an ovary of the patient;
penetrating an ovarian wall of the ovary via a distal tip of the docking device;
advancing a therapeutic element from the docking device into the ovary; and
delivering energy into tissue from inside the ovary using the therapeutic element positioned inside the ovary to ablate a volume of the tissue ranging from 30 mm 3 to 3000 mm 3 within the ovary to treat infertility associated with polycystic ovary syndrome (PCOS).
2. The method of claim 1 , wherein penetrating the ovarian wall of the ovary comprises penetrating the ovarian wall at a single entry point.
3. The method of claim 1 , wherein delivering energy comprises delivering radiofrequency energy.
4. The method of claim 1 , wherein the tissue within the ovary comprises a polycystic ovary or ovarian cyst.
5. The method of claim 1 , wherein delivering energy into the tissue within the ovary comprises delivering energy for 20 to 60 seconds.
6. The method of claim 1 , wherein delivering energy into tissue reduces hormone levels to treat PCOS.
7. The method of claim 1 , wherein the volume of the tissue ablated is from a single ablation.
8. The method of claim 1 , wherein a total affected volume of the tissue ablated within the ovary is 240 mm 3 to 3000 mm 3 .
9. The method of claim 1 , wherein advancing the docking device comprises advancing the docking device into a vaginal canal, the method further comprising penetrating a vaginal wall via the distal tip of the docking device before penetrating the ovarian wall.
10. The method of claim 1 , wherein delivering energy comprises delivering direct heating, cryoablation, cooling, laser, microwave, unfocused ultrasound, partially-focused ultrasound element, focused (HIFU) ultrasound, heated water/saline, steam, or chemical ablation energy.
11. The method of claim 1 , further comprising imaging the ovary during an ablation procedure.
12. The method of claim 11 , wherein imaging the ovary comprises imaging the ovary via an ultrasound transducer in a field of view of the ultrasound transducer.
13. The method of claim 1 , further comprising, after delivering energy, reorienting the therapeutic element within the ovary, and then delivering additional energy within the ovary via the therapeutic element for one or more additional deliveries of energy within the ovary to ablate the tissue within the ovary.
14. The method of claim 1 , further comprising removably coupling the docking device to a handle of a transvaginal ultrasound probe via an adapter configured to be removably coupled to the handle of the transvaginal ultrasound probe.
15. The method of claim 1 , wherein the therapeutic element comprises an active electrode and a return electrode.
16. The method of claim 1 , further comprising measuring temperature at the electrode during an ablation procedure.
17. The method of claim 1 , further comprising measuring tissue temperature during an ablation procedure.
18. The method of claim 17 , further comprising automatically terminating energy delivery if the measured tissue temperature exceeds a predetermined threshold.
19. The method of claim 1 , further comprising measuring tissue impedance during an ablation procedure.
20. The method of claim 1 , wherein the therapeutic element forms a curved configuration upon deployment from a lumen of the docking device within the ovary.
21. The method of claim 1 , further comprising receiving user input comprising at least one of duration of energy emission, power, target temperature, or mode of operation.
