摘要： An electro-thermal apparatus configured to treat tissue includes an electrosurgical cable configured to couple to an electrosurgical energy source. The electrosurgical cable includes supply and return lines that are wound in a double helix arrangement around a dielectric insulator within the electrosurgical cable. An electro-thermal element is provided at a distal end of the electrosurgical cable. The electro-thermal element is in electrical communication with the supply and return lines via corresponding first and second conductive traces. The first and second conductive traces have a patterned geometry and resistivity configured to convert electrical energy provided by the supply and return lines to thermal energy for treating tissue.

摘要： The present application discloses devices that ablate human tissue. The device comprises a catheter with a shaft through which an ablative agent can travel, a liquid reservoir and a heating component, which may comprise a length of coiled tubing contained within a heating element, wherein activation of said heating element causes said coiled tubing to increase from a first temperature to a second temperature and wherein the increase causes a conversion of liquid within the coiled tubing to vapor, a reusable cord connecting the outlet of the reservoir to the inlet of the heating component, and a single use cord connecting a pressure-resistant inlet port of a vapor based ablation device to the outlet of the heating component.

摘要： This invention relates to high-frequency ablation of tissue in the body using a cooled high-frequency electrode connected to a high frequency generator including a computer graphic control system and an automatic controller for control the signal output from the generator, and adapted to display on a real time graphic display a measured parameter related to the ablation process and visually monitor the variation of the parameter of the signal output that is controlled by the controller during the ablation process. In one example, one or more measured parameters are displayed simultaneously to visually interpret the relation of their variation and values. In one example, the displayed one or more parameters can be taken from the list of measured voltage, current, power, impedance, electrode temperature, and tissue temperature related to the ablation process. The graphic display gives the clinician an instantaneous and intuitive feeling for the dynamics and stability of the ablation process for safety and control. This invention relates to monitoring and controlling multiple ground pads to optimally carry return currents during high-frequency tissue ablation, and to prevent of ground-pad skin burns. This invention relates to the use of ultrasound imaging intraoperatively during a tissue ablation procedure. This invention relates to the use of nerve stimulation and blocking during a tissue ablation procedure.

摘要： The present disclosure provides for a device and methods of use to endoluminally ablate and/or occlude a body vessel using a current to perform resistive heating. The device includes a resistive coil having thermistor properties where the resistance of the coil changes as a function of temperature. A control unit will detect the voltage, current, and resistance in the coil during the heating of the coil to determine the temperature of the coil. As occlusion occurs and the cooling effect of blood flow decreases, less power will be required to maintain the coil at a desired temperature. Detecting a large decrease in required power will indicate to the control unit that the body vessel has become occluded.

摘要： The present invention relates to ultrasound assisted tissue welding, more particularly, to a method and device utilizing ultrasound energy for effective closure and sealing of surgical incisions or other wounds. The device of the present invention comprises an ultrasound generator, an ultrasound transducer, a transducer tip at the distal end of the ultrasound transducer, and a radiation surface. A web such as gauze is placed over the incision. In an embodiment, the device may be used to bring the edges of the tissue to be sealed together as the device applies energy to the tissues. Ultrasonic waves emanating from the radiation surface pass through the web and seal the incision creating a continuous seam. The device may be used with or without additional adhesive materials or therapeutic agents.

摘要： A catheter guidance system and method for guiding a catheter through the bloodstream of the patient's cardiovascular system in a medical procedure. The catheter has a front tip with a heating element for slightly heating a media surrounding the front tip in a blood vessel of the patient's cardiovascular system, and two temperature measuring elements located adjacent to and in front and behind the heating element respectively for measuring temperatures in the media at their respective locations. A guidance device is coupled to the catheter for converting the heating power and temperature measurement signals to digital signals, processing the digital signals, and displaying guidance information indicative of the location of the front tip of the catheter relative to the blood vessel wall of the patient's cardiovascular system. The guidance information may be shown by an intuitive traffic light type display.

摘要： A laser can produce pulses of light energy to eject a volume of the tissue, and the energy can be delivered to a treatment site through a waveguide, such as a fiber optic waveguide. The incident laser energy can be absorbed within a volume of the target tissue with a tissue penetration depth and pulse direction such that the propagation of the energy from the tissue volume is inhibited and such that the target tissue within the volume reaches the spinodal threshold of decomposition and ejects the volume, for example without substantial damage to tissue adjacent the ejected volume.

摘要： A method and system for cryotreatment and mapping of target tissue. The cryotreatment system may include a cryotreatment catheter, a mapping catheter including one or more mapping electrodes, and one or more temperature sensors located on the mapping catheter and/or the cryotreatment catheter. The cryotreatment catheter distal tip may be short enough to allow at least one mapping electrode to be positioned proximate the cryoballoon, for example, within 6 mm or less from the cryoballoon. Energy, such as radiofrequency energy, may be delivered to one or more mapping electrodes when one or more temperature sensors indicate a temperature of approximately 0° C. or below at one or more mapping electrode in order to thaw or prevent the formation of ice on the mapping electrodes when positioned proximate a cryoballoon during a cryotreatment procedure in order to recapture cardiac signals.

摘要： A radiofrequency ablation catheter includes an electrode ablation head (10), a Positive Temperature Coefficient (PTC) thermistor (20), and an inner conductor (30), where the electrode ablation head (10) is disposed at an end portion of the inner conductor (30), the PTC thermistor is disposed between the electrode ablation head (10) and the inner conductor (30), and the inner conductor (30) is connected to a cable plug component (40). The radiofrequency ablation catheter and a therapy device including the radiofrequency ablation catheter can precisely control the ablation temperature by means of PTC, such that upon coagulation of tissues, the ablation catheter is not adhered to the tissues, thus avoiding the risk of complications such as rebleeding.
