The present invention relates to an energy transmission module for a vaginal canal treatment apparatus, a method for controlling same, and a treatment method using same according to the present invention allow transmission of energy by means of insertion into the vaginal canal and expansion of the vaginal canal, and thus allow treatment by selectively or complexly generating denaturation such as coagulation and ablation over a large area in a short time, allow one-shot treatment, and allow treatment of an area with folds. Therefore, the efficiency and accuracy of the treatment can be enhanced. Since the tissue in the vaginal canal can be treated even without a surgical operation, user's pain and discomfort can be minimized.

A first followability of the temperature of the heating element in the first phase is higher than a second followability of the temperature in the second phase. The processor is configured to terminate the controlling of following the temperature of the heating element to the target temperature when a parameter is beyond a predetermined range wherein the parameter being defined as a fluctuation between the temperature of the heating element and the target temperature.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

A method of body tissue ablation includes defining an ultrahigh-power ultrashort-duration (UPUD) ablation protocol that specifies an ablation signal having (i) a target ablation power of at least 400 Watts and (ii) a pulse duration that does not exceed three seconds, for creating a specified lesion in tissue in a body of a patient. Contact is made between an ablation probe and the tissue. Using the ablation probe, the ablation signal is applied to the tissue according to the UPUD protocol, which delivers the ablation signal having the specified target ablation power and duration.

A surgical instrument is disclosed that comprises a motor, a radio frequency (RF) energy generator, a first jaw, a second jaw movable relative to said first jaw in response to an actuation from said motor to capture tissue, and a segmented circuit comprising a first electrode configured to measure tissue impedance at a first position and a second electrode configured to measure tissue impedance at a second position. The RF energy generator is configured to transmit RF energy to the tissue by way of said first electrode or said second electrode. A controller is configured to control said motor based on the measured tissue impedances, energize said first electrode with a first amount of RF energy based on the tissue impedance measured at said first position, and energize said second electrode with a second amount of RF energy based on the tissue impedance measured at said second position.

Methods for estimating of the effectiveness of catheter ablation procedures to form lesions, and particular lesions which together form an ablation segment of an ablation line. Lesion effectiveness parameters are received, and effectiveness, optionally the joint effectiveness, of corresponding ablations (optionally planned, current, and/or already performed) is estimated. In some embodiments, estimating is based on use by computer circuitry of an estimator constructed based on observed associations between previously analyzed lesion effectiveness parameters, and observed lesion effectiveness. Additionally or alternatively, estimators may be constructed based on analytic functions. The estimator is used by application to the received lesion effectiveness parameters.

Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

A method for producing an image of a body tissue surface. The method includes transforming a source 3-D model of the body tissue surface into a flattened model comprising details of the body tissue surface represented visually on an unwrapped and flattened surface, wherein the flattened model represents transformed positions of the source 3-D model of the body tissue surface defined between a first edge and a second edge. The first edge is formed about a lumen defined by the body tissue surface, and the body tissue surface projects about the lumen to the second edge. The method further includes producing an image from the flattened model.
