In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.

A method for performing electrothermal therapy (ETT) includes inserting one or more electrodes into a target tissue, inserting one or more temperature sensors into the target tissue, selecting a pulse waveform for a plurality of electrical pulses, and delivering to the target tissue the plurality of electrical pulses having the selected pulse waveform through the one or more electrodes, wherein a delay between ones of the plurality of electrical pulses is selected based on a temperature reading from the one or more temperature sensors.

Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

Dermatological systems and methods for providing a therapeutic laser treatment wherein the duration of a therapeutic laser pulse is based on one or more determinations of a surface temperature of the skin during the delivery of the pulse. Initiation of the therapeutic laser pulse may be based on sensed skin temperature during a cooling of the skin prior to initiation of the pulse.

A method for determining a suitable set of parameters for operating a light source within a photo-thermal targeted treatment system for targeting a chromophore embedded in a medium is disclosed. The method includes, before administration of a treatment protocol: 1) administering at least one laser pulse from the light source at a preset power level to a location to be treated, the preset power level being below a known damage threshold; 2) measuring a skin surface temperature at the location to be treated, following administration of the at least one laser pulse; 3) estimating a relationship between the parameters for operating the light source and the skin surface temperature; and 4) defining a safe operating range for the parameters for operating the light source in order to avoid thermal damage to the medium at the location to be treated while still effectively targeting the chromophore in administering the treatment protocol.

Combined methods for treating a patient using time-varying magnetic field are described. The treatment methods combine various approaches for aesthetic treatment. The methods are focused on enhancing a visual appearance of the patient.

Ablation of cardiac tissue is carried out by inserting a probe having an ablation electrode and a plurality of microelectrodes into a body of a living subject to establish contact between two of the microelectrodes and target tissue, and energizing the ablation electrode. While the ablation electrode is energized impedances are measured between the microelectrodes, and the power level of the ablation electrode adjusted according to the impedances.

A computer implemented method for estimating tissue parameters, includes collecting data, from a surgical system including an instrument and an energy source, the data including at least one electrical parameter associated with delivering energy from the instrument to tissue, communicating the data to at least one machine learning algorithm, determining, using the at least one machine learning algorithm, a tissue parameter based upon the data, communicating the determined tissue parameter to a computing device associated with the energy source for use in formulating an energy-delivery algorithm for delivering energy from the instrument to tissue, and delivering energy from the instrument of the surgical system to tissue in accordance with the energy-delivery algorithm.

A temperature measurement system for measuring a temperature of a measured surface includes: 1) a first temperature sensor; and 2) a reference surface including a second temperature sensor integrated therein. The first temperature sensor includes a field of view simultaneously covering both at least a portion of the measured surface and at least a portion of the reference surface, thus is configured for simultaneously taking a first measurement of both the portion of the measured surface and the portion of the reference surface. The first measurement of the reference surface taken by the first temperature sensor is compared to a second measurement taken by the second temperature sensor for use in calibrating the first temperature sensor.
