  • Patent number: 10073125
    Abstract: A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.

  • Patent number: 9566107
    Abstract: A method of ablating a tissue site includes at least two stages. A first stage involves conducting bipolar ablation between a first pair of electrodes situated in an opposing arrangement on opposing sides of the tissue site to form a pair of opposing first stage ablation regions extending from respective sides of the tissue towards the center. A second stage involves conducting bipolar ablation between a second pair of electrodes situated in a diametrical arrangement with respect to the first stage ablation regions, which forms a second stage ablation region intermediate the pair of first stage ablation regions. The second stage completes the ablation through the entire depth of the tissue site. Since the overall process can accommodate incomplete ablation during the first stage, lower power, reduced ablation times or both may be used during the first stage, avoiding overheating and with a decrease in ablated tissue volume.

    Abstract: Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.

  • Patent number: 8853600
    Abstract: A system and method for treating subcutaneous histological features without affecting adjacent tissues adversely employs microwave energy of selected power, frequency and duration to penetrate subcutaneous tissue and heat target areas with optimum doses to permanently affect the undesirable features. The frequency chosen preferentially interacts with the target as opposed to adjacent tissue, and the microwave energy is delivered as a short pulse causing minimal discomfort and side effects. By distributing microwave energy at the skin over an area and adjusting power and frequency, different conditions, such as hirsuitism and telangiectasia, can be effectively treated.

  • Publication number: 20140207217
    Abstract: Radiofrequency (RF) skin treatment devices and methods are provided herein. RF energy is delivered via electrodes in a phase-controlled manner which heats skin volumes below the surface more than the skin surface itself. At least one electrode at least partially encloses at least one other electrode. The combination of controlling the phases of the RF energy delivered to different electrodes and the enclosing configuration of the electrodes allows concentrating the delivered energy in specific regions below the skin surface at a particularly high efficiency. Configurations of the enclosing and the enclosed electrodes, their forms and combinations with other electrodes and the phase polarities applied to the electrodes are also provided.

  • Patent number: 8788060
    Abstract: Methods, apparatus, and systems for transcutaneously treating tissue located beneath a skin surface with electromagnetic energy delivered from a treatment electrode. A portion of the treatment electrode is contacted with the skin surface. While maintaining the contact between the portion of the treatment electrode and the skin surface, the electromagnetic energy is delivered from the treatment electrode in a plurality of power pulses through the skin surface to the tissue over a treatment time with a time gap between each consecutive pair of the pulses to lower a level of pain perceived by a patient.

  • Patent number: 8731684
    Abstract: Apparatus for aligning an ablation catheter and a temperature probe relatively for an ablation procedure includes an ablation catheter with a first antenna for ablating tissue at an ablation site in a patient's body and a temperature probe for placement in a body passage having a wall portion adjacent to the ablation site so that a second antenna in the probe is positioned opposite the first antenna. A microwave source provides a pulse modulated microwave signal to one of the antennas and a radiometer is in circuit with the other antenna. A synchronizing device in circuit with the microwave source and the radiometer enables the radiometer to synchronously detect the microwave signal so that the radiometer provides an alignment signal whose strength reflects the degree of alignment of the first and second antennas which signal may be used to control an alignment display. An alignment method using the apparatus is also disclosed.

    Abstract: Methods and apparatus are provided for renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. It is expected that renal neuromodulation (e.g., denervation) may, among other things, reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease. Embodiments of the present invention are configured for percutaneous intravascular delivery of pulsed electric fields to achieve such neuromodulation.
