  • Patent number: 11919407
    Abstract: This disclosure provides systems, methods and apparatus for detecting foreign objects. In one aspect an apparatus for detecting a presence of an object is provided. The apparatus includes a resonant circuit having a resonant frequency. The resonant circuit includes a sense circuit including an electrically conductive structure. The apparatus further includes a coupling circuit coupled to the sense circuit. The apparatus further includes a detection circuit coupled to the sense circuit via the coupling circuit. The detection circuit is configured to detect the presence of the object in response to detecting a difference between a measured characteristic that depends on a frequency at which the resonant circuit is resonating and a corresponding characteristic that depends on the resonant frequency of the resonant circuit. The coupling circuit is configured to reduce a variation of the resonant frequency by the detection circuit in the absence of the object.

  • Patent number: 11439357
    Abstract: A method for anatomical diagnosis includes measuring, using a catheter that includes a position sensor and an electrode, over multiple cycles of a beating heart, electrical activity and mechanical motion at a plurality of locations contacted by the catheter on a heart wall within a chamber of the heart. Based on the measured mechanical motion, a magnitude of a mechanical strain is computed over the cycles at the locations. In one embodiment, the computed strain is used in identifying a group of the locations at which the magnitude of the mechanical strain is below a predefined strain threshold and a voltage of the electrical activity is below a predefined voltage threshold as a locus of scar tissue. In another embodiment, a pathological condition of the heart is identified based on a characteristic of the mechanical strain computed over the left ventricle during the diastolic phase.
