Methods and systems for the manipulation of ovarian tissues
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 also be useful in the treatment of infertility associated with PCOS.
1. A system for performing an ovarian procedure, the system configured for use in combination with a transvaginal probe comprising a handle and an ultrasound transducer, the system comprising:
an ovarian tissue apparatus, the ovarian tissue apparatus comprising a docking device having an elongate body, a longitudinal axis, a proximal portion, a distal portion having an opening and a distal end having a needle tip configured to pierce a vaginal wall and an ovarian wall, wherein the opening is disposed proximal to the needle tip, and defining a lumen therethrough, an anchoring member disposed for reciprocation within the lumen and having a distal region, the distal region transitioning to a curved shape when extended through the opening into ovarian tissue, a therapeutic element disposed on the distal region of the anchoring member, and a lock at the proximal portion, the lock configured to lock the docking device such that the therapeutic element is deployable in a first orientation relative to the transvaginal probe for energy emission into the ovarian tissue and to lock the docking device such that the therapeutic element is deployable in a second orientation relative to the transvaginal probe, having a different angle relative to the longitudinal axis from the first orientation, for further energy emission into the ovarian tissue; and
a generator configured to supply energy to the therapeutic element to cause the therapeutic element to emit energy into the ovarian tissue for the ovarian procedure.
2. The system of claim 1 , wherein the lock is configured to aid in deployment of the anchoring member by maintaining planar orientation of the anchoring member relative to the ultrasound transducer during a procedure on an ovary.
3. The system of claim 1 , wherein the distal region of the anchoring member has a straightened length when disposed within the lumen.
4. The system of claim 3 , wherein the anchoring member comprises two curved structures.
5. The system of claim 3 , wherein the straightened length ranges between about 5.0 and about 40 mm.
6. The system of claim 3 , wherein the curved shape of the distal region has a radius of curvature ranges between about 3 and about 16 mm.
7. The system of claim 1 , wherein the therapeutic element comprises a pair of electrodes disposed on the distal region.
8. The system of claim 1 , wherein the therapeutic element comprises an active electrode and a return electrode.
9. The system of claim 1 , wherein the lock comprises a notch configured to mate with the docking device when an alignment adapter is in a locked position.
10. The system of claim 1 , wherein the generator is configured to supply radiofrequency energy at a power of between about 1 watts and 40 watts, and for a duration of about 10 to about 120 seconds.
11. The system of claim 1 , wherein the generator is configured to supply continuous or pulsed radiofrequency energy.
12. The system of claim 1 , wherein the distal end of the docking device comprises one or more attachment elements for releasably securing an ovary.
13. The system of claim 12 , wherein the one or more attachment elements comprise a hook, needle, or barb.
14. The system of claim 1 , wherein a portion of at least one of the docking device, the anchoring member or the therapeutic element comprises an echogenic material.
15. The system of claim 1 , wherein the generator is configured to supply the energy to the therapeutic element to cause the therapeutic element to emit the energy into the ovarian tissue to treat infertility associated with polycystic ovary syndrome.
16. The system of claim 1 , wherein the therapeutic element comprises an electrode, a cryoablation element, a cooling element, a laser, or a combination thereof.
