  • Patent number: 11819712
    Abstract: Apparatus and methods are provided for applying ultrasound pulses into tissue or a medium in which the peak negative pressure (P?) of one or more negative half cycle(s) of the ultrasound pulses exceed(s) an intrinsic threshold of the tissue or medium, to directly form a dense bubble cloud in the tissue or medium without shock-scattering. In one embodiment, a microtripsy method of Histotripsy therapy comprises delivering an ultrasound pulse from an ultrasound therapy transducer into tissue, the ultrasound pulse having at least a portion of a peak negative pressure half-cycle that exceeds an intrinsic threshold in the tissue to produce a bubble cloud of at least one bubble in the tissue, and generating a lesion in the tissue with the bubble cloud. The intrinsic threshold can vary depending on the type of tissue to be treated. In some embodiments, the intrinsic threshold in tissue can range from 15-30 MPa.

  • Patent number: 10790583
    Abstract: A low-profile dual-band high-isolation antenna module is fixed on a substrate and includes two high-frequency antennas and two low-frequency antennas located on two opposite sides of the substrate respectively. The bottom ends of the low-frequency antennas are connected to a grounding of the substrate. A decoupling element is disposed between the high-frequency antennas and the low-frequency antennas. The top end of each high-frequency antenna forms a bent portion, and so does the top end of each low-frequency antenna. The decoupling element has two ends extending to positions corresponding respectively to the low-frequency antennas but is not in contact with the low-frequency antennas or the high-frequency antennas. The bottom end of the decoupling element is connected to the grounding through at least one metal strip. The bent portions effectively reduce the space occupied by the antennas while the decoupling element provides isolation between the antennas.
