  • Publication number: 20250090229
    Abstract: An exemplary microwave ablation system is provided. The system may use a switching antenna for both microwave heating of target tissue and microwave radiometry to monitor the temperature of the heated tissue to ensure that the desired temperatures are delivered to adequately treat the target tissue and achieve therapeutic goals. The system may integrate switching components into the switching antenna, which eliminates error from heating of the reference termination and heating of the electrical cables.

  • Publication number: 20240398474
    Abstract: An exemplary ablation system is provided. The system is designed for safe and efficacious energy delivery into tissue by, for example, emitting energy in a controlled, repeatable manner that allows for feedback and energy emission titration based on sensed parameters (e.g., tissue temperature) measured during ablation. The system may include a switching antenna for both heating of target tissue and radiometry to monitor the temperature of the heated tissue. For example, the switching antenna may include a monopole formed by proximal and distal radiating elements, such that the proximal radiating element includes a short to defeat a choke action of the proximal radiating element. The system further includes a processor for calculating the temperature of the target tissue and estimating volume of the ablation lesion based on the target tissue temperature.

  • Patent number: 10126180
    Abstract: A transducer for noninvasively determining an internal temperature of a location of interest in a body of a subject may be configured to receive native temperature signals originating from the location of interest without substantially receiving interfering signals. Such a transducer may include one or more shielding features for preventing interference. In addition, such a transducer may include a dielectric cavity configured or positioned to increase the native temperature signals sensed, or received, by the antenna. A transducer may be configured to multiplex signals that are indicative of a temperature of a location of interest within the body of a subject and reference temperature signals. Such a transducer may include a connector that facilitates the communication of a multiplexed signal, such as a connector for a coaxial cable. The connector of a transducer may be configured to swivel relative to an end of a cable that has been coupled thereto. Systems including such a transducer are also disclosed.

  • Patent number: 9958343
    Abstract: Apparatuses and systems for determining a temperature of a targeted subject are disclosed. A temperature sensing system may include an antenna for sensing electromagnetic radiation (e.g., microwaves, etc.) emanating from the source. Based on that electromagnetic radiation, the antenna generates a temperature signal. A switch, which is located at or adjacent to an output of the antenna, receives the temperature signal, as well as a reference signal from a termination. The temperature signal and the reference signal are conveyed along a cable to a signal converter. Signal-altering events that affect the temperature signal as it is conveyed also affect the reference signal. Thus, any error caused by a signal-altering event automatically cancels out. The signal converter measures or otherwise processes the temperature signal and, since there is no need to correct for errors in the temperature signal, the reference signal, and accurately calculates the temperature of the source.

  • Patent number: 9795304
    Abstract: A low profile temperature transducer has a working surface for placement against a body surface and a first output. The transducer is a flat laminate composed of alternating conductive and dielectric layers. The laminate defines at least one slotline antenna for exposure to the body surface to pick up thermal emissions from the underlying tissue at depth. A feed network having a characteristic impedance is connected to the first output and a slotline-to-stripline transition is connected between the at least one antenna and the feed network, the transition providing a match between the impedance at the at least one antenna and the characteristic impedance. Also, a temperature sensor may be present at the working surface to detect the body surface temperature under the transducer, that surface temperature being used to calculate actual temperature at depth.

  • Publication number: 20160317210
    Abstract: The present invention provides systems and methods for temperature-controlled ablation using radiometric feedback. An interface module may include (a) a processor; (b) a first input/output (I/O) port to receive digital radiometer and digital thermocouple signals from an integrated catheter tip (ICT); (c) a second I/O port to receive ablative energy from a generator; (d) a temperature display; (e) a patient relay; (f) a computer-readable medium storing instructions for causing the processor to: (i) calculate a temperature adjacent to the ICT based on the digital radiometer and thermocouple signals and operation parameters; (ii) cause the temperature display to display the calculated temperature; and (iii) close the patient relay to pass ablative energy received on the second I/O port to the first I/O port; and (g) a temperature control subsystem to regulate the ablative power based on the calculated temperature.
