Vaginal remodeling device and methods
This invention relates generally to apparatus and methods for tightening tissue of the female genitalia by heating targeted connective tissue with radiant energy, while cooling the mucosal epithelial surface over the target tissue to protect it from the heat. Embodiments include a handle and treatment tip that has both an energy delivery element and a cooling mechanism. The handle may be a two-handed handle allowing control even while rotating and maneuvering the treatment around the genital opening. The apparatus or system may also include an integrated controller, which may confirm tissue contact without applying RF energy, based only on the temperature of the applicator and the time since the last application of energy from the applicator.
1. A method for remodeling a therapeutic zone within a target tissue underlying a mucosal epithelium of female genital tissue of female genitalia, the method comprising:
cooling a disposable treatment tip of an applicator from an internal lumen in the applicator, wherein the disposable treatment tip includes one or more atraumatic energy-delivery elements;
remodeling the therapeutic zone of target tissue;
determining, with a controller, a time since the one or more atraumatic energy-delivery elements of the disposable treatment tip was last activated,
taking the temperature of one or more sites on the disposable treatment tip;
determining if the one or more energy-delivery elements are in contact with the tissue without applying RF energy to the tissue by comparing the temperature of the one or more sites on the treatment tip to a threshold function for the time since the treatment tip was last activated; and
indicating if the one or more atraumatic energy-delivery elements is in contact with the tissue.
2. The method of claim 1 , further comprising confirming contact with the tissue and the one or more energy-delivery elements based on the temperature of a portion of the treatment tip on or near the one or more energy-delivery elements and the time since the treatment tip was last activated.
3. The method of claim 2 , wherein the step of confirming contact comprises confirming contact without applying energy.
4. The method of claim 1 , wherein the step of cooling the treatment tip comprises spraying coolant within the internal lumen against an internal surface of the treatment tip.
5. The method of claim 4 , further comprising recycling the coolant.
6. The method of claim 1 , further comprising connecting the treatment tip to an elongate handle of the applicator configured to be held in two hands.
7. The method of claim 1 , further comprising heating the target tissue using the treatment tip, and wherein heating the target tissue comprises heating the treatment tip to a temperature between about 45° C. and about 80° C. by applying energy from the treatment tip.
8. The method of claim 1 , wherein the method further comprises cooling the epithelium by contacting the epithelium with the treatment tip.
9. The method of claim 1 , further comprising cooling the epithelium to a temperature between about 0° C. and about 10° C.
10. The method of claim 1 , further comprising heating the target tissue using the treatment tip, and wherein the cooling precedes the heating, and continues during the heating.
11. The method of claim 1 , further comprising heating the target tissue using the treatment tip, and wherein the cooling is during the heating, and continues after heating.
12. The method of claim 1 , wherein the method comprises contacting the epithelium with the treatment tip at a one or more contact sites during a procedure, the treatment tip comprising an energy delivery element adapted to heat the target tissue.
13. The method of claim 1 , wherein the female genitalia includes the vulva and the vagina.
14. The method of claim 1 , wherein the female genitalia includes the introitus.
15. The method of claim 1 , wherein the female genitalia includes a portion of the vagina extending from the introitus inwardly to a location from about 1 cm to about 3.5 cm in from the introitus.
16. The method of claim 1 , wherein the female genitalia includes a portion of the vagina circumferentially around its wall from about 1 o'clock to about 11 o'clock, wherein the aspect closest to the urethra is at 12 o'clock.
17. The method of claim 1 , wherein the female genitalia includes a portion radiating outward from the introitus to Hart's line.
18. The method of claim 1 , wherein the female genitalia includes the mucosal surfaces of the labia minora.
19. The method of claim 1 , wherein the target tissue includes submucosa and muscularis below the mucosal epithelium.
20. The method of claim 1 , further comprising heating the target tissue using the treatment tip, and wherein the heating does not modify the mucosal epithelium of the genital tissue.
21. The method of claim 1 , wherein remodeling comprises contracting target tissue.
22. The method of claim 1 , wherein remodeling comprises tightening the introitus.
23. The method of claim 1 , wherein remodeling comprises tightening the vagina.
24. The method of claim 1 , wherein remodeling comprises denaturing collagen.
25. The method of claim 1 , wherein remodeling comprises tightening collagen-rich sites in the target tissue.
26. The method of claim 1 , further comprising heating the target tissue using the treatment tip.
27. The method of claim 1 , wherein the controller is configured to determine contact with the target tissue and generate a contact map comprising a graphical map representing relative positions of the plurality of energy applicator regions on the energy delivery element, the graphical map showing contact status of each of the energy applicator regions.
