Patent number: 9050102Abstract: 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.Type: GrantFiled: March 14, 2012Date of Patent: June 9, 2015Assignee: MINERVA SURGICAL INC.Inventor: Csaba Truckai

Patent number: 9050103Abstract: A wall of a uterus is ablated by expanding a structure in the uterus and applying energy across the wall of the structure into the uterine wall. An exterior surface of the structure conforms to an inner wall of the uterus, and the energy may cause vapor to collect between the wall and the structure. The vapor is released by providing a barrier to release which is inflated at a pressure above which the barrier at least partially collapses to allow the vapor to leave the uterus.Type: GrantFiled: March 22, 2012Date of Patent: June 9, 2015Assignee: MINERVA SURGICAL INC.Inventor: Csaba Truckai

Patent number: 8715278Abstract: 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.Type: GrantFiled: November 11, 2009Date of Patent: May 6, 2014Assignee: Minerva Surgical, Inc.Inventors: Akos Toth, Csaba Truckai

Publication number: 20130310705Abstract: 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. If the flow rate drops to zero or close to zero, this indicates that the uterine cavity is intact and not perforated. If the flow rate does not drop to zero or close to zero, this indicates that a fluid flow is leaking through a perforation in the uterine cavity into the uterine cavity or escaping around an occlusion balloon that occludes the cervical canal.Type: ApplicationFiled: July 17, 2013Publication date: November 21, 2013Applicant: Minerva Surgical, Inc.Inventor: Akos Toth
