Neuromodulation catheter systems with controlled irrigation capabilities and methods for using such systems are disclosed herein. One such method includes, for example, positioning an irrigated neuromodulation catheter at a treatment site within a renal blood vessel of a human patient, delivering neuromodulation energy at the treatment site, and delivering irrigation fluid to the treatment site having characteristics coordinated with the delivered energy. The characteristics can be adjusted to maintain an energy delivery element and/or tissue of the blood vessel at a constant temperature as power is increased. The method can further include monitoring at least one parameter of the tissue and/or of the energy delivery element, and adjusting the neuromodulation energy and/or the characteristics of the irrigation fluid if the at least one parameter falls outside of a treatment range of values.

Pursuant to embodiments of the present invention, a method of performing electronically controlled electrotherapy may include modifying or killing target cells and simultaneously modifying a secondary outcome by delivering electrical pulses and dynamically adjusting an energy delivery profile of the electrical pulses in response to a measurement. The secondary outcome may be a physical outcome, a biological outcome, and/or a systemic outcome.

A method and system for assessing lesion formation in tissue is provided. The system includes an electronic control unit (ECU). The ECU is configured to acquire values for first and second components of a complex impedance between the electrode and the tissue, and to calculate an index responsive to the first and second values. The ECU is further configured to process the ECI to assess lesion formation in the tissue.

A method for performing an electrosurgical procedure at a surgical site on a patient includes continually sensing electrical and physical properties proximate the surgical site that includes acquiring readings of tissue electrical impedance with respect to time at the surgical site; identifying the minima and maxima of the impedance readings with respect to time; and correlating the minima and/or the maxima of the impedance readings with hydration level and/or hydraulic conductivity in the tissue at the surgical site. The method also includes controlling the application of electrosurgical energy to the surgical site to vary energy delivery based on the step of correlating the minima and/or the maxima of the impedance readings with the hydration level/or and the hydraulic conductivity in the tissue at the surgical site. The process may be an ablation process.

Described herein are methods and systems for performing a procedure for ovarian rebalancing. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may also be useful in the treatment of infertility associated with PCOS.

A method for ablating a patient, consisting of ascertaining a CHA.sub.2DS.sub.2-VASc score for the patient and inserting a probe into the patient, so as to contact a pulmonary vein of the patient. The method further includes applying energy via the probe so as to ablate the pulmonary vein until pulmonary vein isolation (PVI) is achieved. When PVI is achieved and the CHA.sub.2DS.sub.2-VASc score is less than a preset value, ablation of the pulmonary vein is ceased. When PVI is achieved and the CHA.sub.2DS.sub.2-VASc score is greater than or equal to the preset value, energy is applied to perform a further ablation.

A cosmetic method for treating a skin of a person is presented, the method comprises inserting one or more needles to one or more depths into the skin of the person such that at least a tip of at least one needle of the one or more needles is deployed within a muscle layer of the person's skin; applying a negative DC voltage to the one or more needles, while a skin of the person is in contact with a positive electrode to form one or more closed circuits of DC current through the person's body; and providing the DC current for a pre-selected amount of time to damage and/or ablate muscles and/or muscle nerve cells in the muscle layer; thereby providing a skin treatment comprising reducing and/or smoothing wrinkles from the person's skin.

Disclosed are a method and apparatus for safety control of radio frequency operation, and a radio frequency host. The method includes: when connecting ends of a plurality of radio frequency circuits connect an operated object to a radio frequency host, acquiring detection values of the plurality of radio frequency circuits; determining whether change amounts of the detection values reach a preset value range; when a number of target radio frequency circuits reaching the preset value range is not less than a preset number, selecting the preset number of target radio frequency circuits from the target radio frequency circuits according to a preset selection rule as radio frequency input circuits, and inputting radio frequency energy into the radio frequency input circuits; when the number of target radio frequency circuits reaching the preset value range is less than the preset number, not inputting radio frequency energy into any radio frequency circuit.

Disclosed are a data adjustment method in a radio frequency operation and a radio frequency host. The data adjustment method includes acquiring set power data corresponding to the radio frequency operation, setting an output power of a radio frequency signal according to the set power data, and outputting the radio frequency signal to an object of the radio frequency operation; detecting physical characteristic data of the object in real time, and determining whether the physical characteristic data exceeds a preset range; adjusting the radio frequency output power when the physical characteristic data exceeds the preset range; and adjusting the preset range according to the physical characteristic data detected in real time in a preset period of time before a present moment when the physical characteristic data does not exceed the preset range. As a result, the safety and success rate of the radio frequency operation is improved.

Disclosed are an ablation operation prompting method, an electronic device, and a computer-readable storage medium. The method includes: acquiring an image of an ablation site and displaying the image on a screen when an ablation task is triggered; acquiring position data of a currently-being-ablated target ablation point, marking the target ablation point in the image according to the position data; acquiring the elapsed ablation time and the temperature of the target ablation point in real time, and determining the ablation status of the target ablation point according to the elapsed ablation time and the temperature; and generating a schematic real-time dynamic change diagram of the target ablation point according to the ablation status, and displaying the schematic diagram on the screen, to indicate the real-time ablation status change of the target ablation point.
