Abstract

In methods and devices for treating a body canal or cavity, an internal applicator has an insertable part or section for insertion into the body canal or cavity (e.g. vagina or anal canal) and non-insertable part which may be detachable from a handle or second part of the device. The insertable part may include a plurality of energy delivery elements, optionally spaced apart in an array. During treatment the insertable part is positioned into or onto the body canal or cavity. The treatment may then proceed without additional movement of the insertable part. The energy delivery elements may be activated in predetermined order.

Dependent claims

A method for a female genital tissue treatment comprising:

providing an internal applicator including an insertable part and a non-insertable part;
assembling the insertable part with first and second detachable parts along a length of the insertable part, wherein the first detachable part includes a first ring-shaped circular radiofrequency electrode encircling or around the first detachable part and the second detachable part includes a second ring-shaped circular radiofrequency electrode encircling or around the second detachable part;
with the first and second ring-shaped circular radiofrequency electrodes having a length in a range of 0.1 mm to 100 mm and a radius in a range of 0.2 cm to 20 cm;
wherein the non-insertable part, the first and second detachable parts and centers of the first and second ring-shaped circular radiofrequency electrodes are configured to be on the same longitudinal axis;
wherein the first and second ring-shaped circular radiofrequency electrodes are perpendicular to the longitudinal axis;
and
wherein the first and the second ring-shaped circular radiofrequency electrodes are spaced apart from each other by a distance in a range of 0.01 mm to 20 mm;
inserting the insertable part having a length in a range of 0.75 cm to 20 cm at east partially into a vagina;
transferring a radiofrequency energy into the genital tissue of the vagina with the first and second ring-shaped circular radiofrequency electrodes;
wherein the radiofrequency energy is in a range of 350 kHz to 100 MHz with an output up to 450 W providing an energy flux in a range 0.001 W/cm2 to 1500 W/cm2;
