| 20120116378 | ENDOMETRIAL ABLATION WITH A DEVICE THAT CONFORMS TO SYMMETRIC OR ASYMMETRIC UTERINE CAVITIES - Methods, systems and devices for endometrial ablation. In accordance with a method, a working end of an RF ablation device is positioned in a patient uterus to contact endometrial tissue, the working end comprising a dielectric wall capable of non-expanded and expanded shapes and for conforming to an asymmetric or symmetric shape of the patient's uterine. | 05-10-2012 |
| 20120101498 | SYSTEMS AND METHODS FOR ENDOMETRIAL ABLATION - Methods, systems and devices for endometrial ablation. In accordance with a method, a working end of an RF ablation device is positioned in a patient uterus to contact endometrial tissue, the working end comprising a dielectric wall capable of non-expanded and expanded shapes for expanding an energy-delivery surface against the patient's uterine. A resistively heatable material carried by the energy-delivery surface and an electrical source is operatively coupled to the resistively heatable material such that electrical current provided by the electrical source causes the resistively heatable material to resistively heat. | 04-26-2012 |

| 20110112523 | SYSTEMS, METHODS AND DEVICES FOR ENDOMETRIAL ABLATION UTILIZING RADIO FREQUENCY - Methods, systems and devices for endometrial ablation. In accordance with a method, a working end of an RF ablation device is positioned in a patient uterus to contact endometrial tissue, the working end comprising a dielectric. Radiofrequency energy is applied for a first interval of time at constant power, the power being sufficient to capacitively couple current across the dielectric to the contacted endometrial tissue. A voltage parameter measured within the first interval, and radiofrequency energy is applied at a constant voltage over a second, treatment interval to ablate endometrial tissue, the constant voltage being related to the recorded voltage. | 05-12-2011 |
