A catheter includes an insertion tube, first and second electrodes, and a contact-force sensor. The insertion tube is configured to insert the catheter into a patient body. The first and second electrodes are coupled to a distal-end of the catheter at a predefined distance from one another, and are configured to: (i) receive, via the insertion tube, one or more irreversible electroporation (IRE) pulses, and (ii) apply the IRE pulses, between the first and second electrodes, to tissue of the patient body. The contact-force sensor is disposed between the first and second electrodes and is configured to produce an electrical signal indicative of a contact force applied between the distal-end and the tissue.

Some embodiments provide a method of providing ultrasound energy having a stable power output. The method can comprise providing ultrasound energy from a ultrasound transducer; determining a power level threshold of the ultrasound energy; monitoring a power level of the ultrasound energy over time of the ultrasound energy; communicating a power level to a controller; adjusting the frequency of the ultrasound energy upon a change in the power level; and maintaining the power level threshold of the ultrasound energy.

The present application discloses a method and apparatus that use a two-dimensional array or matrix of RF electrodes arranged on a substrate. In one example, the RF electrodes are individually addressable. In another example, the RF electrodes are arranged in addressable clusters. The clusters of the RF electrodes could be non-symmetrical dusters of electrodes.

A portable electrosurgical device (ESD) has a housing, a probe connected to the housing and a heating element connected to the probe for destroying human tissue. The heating element is detachable from the probe and/or the probe with heating element can be detachable from the housing. The user can set a drive signal's electrical characteristics, such as operating frequency, duty cycle, peak voltage and the like for a customized drive signal formed in the ESD based on the heating element used. Memory storage allows for storage of inputted data from a keyboard, downloaded reference documents and information off the Internet from an Ethernet connector that can be displayed for reference on a screen of the ESD. Another even more compact ESD is an integral one-piece portable device having a type of pistol hand-held grip, dis-connectable probe, and a rechargeable, removable battery in the handle provides approximately 30, one-minute treatments on a single battery charge.

According to an aspect of some embodiments of the present invention there is provided a method of dynamically adapting a facial treatment based on a current facial skin profile, comprising: using at least one sensor for measuring at least one current value of at least one variable skin characteristic of facial skin of a patient; acquiring at least one personal skin characteristic of facial skin of the patient; calculating a current facial skin status of the patient according to the at least one personal skin characteristic and the at least one current value; determining instructions to operate a treatment applicator according to the current facial skin status; and instructing the treatment applicator according to the instructions.

Tumors can be treated with an alternating electric field. The size of cells in the tumor is determined prior to the start of treatment by, for example, biopsy or by inverse electric impedance tomography. A treatment frequency is chosen based on the determined cell size. The cell size can be determined during the course of treatment and the treatment frequency is adjusted to reflect changes in the cell size. A suitable apparatus for this purpose includes a device for measuring the tumor impedance, an AC signal generator with a controllable output frequency, a processor for estimating the size of tumor cells and setting the frequency of the AC signal generator based thereon, and at least one pair of electrodes operatively connected to the AC signal generator such that an alternating electric field is applied to the tumor.

Devices, kits, and methods described herein are usable for medical treatments by generating local maxima using constructive interference of multiple oscillator outputs. Where constructive interference occurs between the oscillator waves, the output signal can have significant strength to cause heating and coagulation at a bleeding vessel, for instance, while at areas with little interaction (or with destructive interference) there is insufficient power dissipated by the output signal to cause heating sufficient to cause coagulating heating.

A medical device including an evaluation unit and an electrode line. The electrode line includes at least one temperature sensor. The temperature sensor delivers a temperature signal to the evaluation unit. The evaluation unit evaluates periodic fluctuations of a signal level of the temperature signal and generates an evaluation output signal qualifying constant wall touching of the electrode line according to whether periodic fluctuations of a signal level of the temperature signal lie below or above a predetermined limit value.

The apparatus includes a source of treatment radiation which is arranged to generate radiation at one of a plurality of radiation parameters (such as power levels), a control unit and a base unit. The control unit is arranged to removably dock with the base unit and includes a sensor which can sense one of a plurality of skin parameters, and an actuator for enabling a user to interface with the control unit. The control unit operates in a sensing mode, in which the control unit is undocked from the base unit to sense a parameter of skin to be treated (such as skin tone), and a control mode in which the control unit is docked to the docking unit and is arranged to select the power level of the radiation generated by the source.
