Abstract
Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.
Claims12
A medical method for ablating tissue, comprising:
- creating a negative pressure in a neutral gas in a fluid-tight chamber of a dielectric positioned adjacent to targeted tissue;
- applying RF energy to ignite and maintain a plasma in the negative pressure neutral gas;
- adjusting the negative pressure toward an ambient pressure while maintaining the plasma, wherein the dielectric delivers energy to the targeted tissue.
