  • Publication number: 20200235464
    Abstract: An antenna for a medical implant device is described. The antenna has a magnetic field radiator portion and an electric field radiator portion coupled to the magnetic field radiator portion. The magnetic and electric field radiators are arranged to result in generation, by the antenna, of at least one of a transverse electric leaky wave and a transverse magnetic leaky wave in lossy body tissue of a human or animal body such that the lossy body tissue acts as a waveguide for the transverse electric leaky wave or transverse magnetic leaky wave, whereby to optimize at least one of the efficiency of the antenna and the far field gain of the antenna.

  • Patent number: 10264981
    Abstract: A introducer is disclosed that includes an introducer sheath for introducing a catheter into a blood vessel at an insertion point, a plurality of electrodes on the introducer sheath, a flush line coupled to the introducer sheath including a proximal end and a distal end. In addition, the introducer includes an impedance assessment unit coupled to the flush line between the proximal end and the distal end and electrically coupled to the electrodes. The impedance assessment unit is configured to inject a predetermined current or voltage into a first of the plurality of electrodes and measure a resulting voltage or current, respectively, from a second of the plurality of electrodes.

  • Publication number: 20190038214
    Abstract: In one example, a sensor is configured to be implanted into a patient's body. The sensor has at least one sensing element, a measurement device in communication with the at least one sensing element, and an internal wireless communicator in communication with the measurement device. The at least one sensing element includes a resistor, and the measurement device includes a capacitor. The measurement device measures a discharge time of the capacitor through the resistor so as to generate a measurement value that is proportional to a value of an anatomical property of the anatomical body, such as strain, that is observed by the sensor. The internal wireless communicator wirelessly communicates the measurement value through skin of the patient to an external wireless communicator situated outside of the patient's body.

  • Publication number: 20110304437
    Abstract: A sensor system having a sharply defined zone of active sensing comprising a compound antenna system comprising an antenna structure disposed in relation to a shield structure and spaced from the shield structure, the shield structure having an open aperture in front of the antenna structure in the direction of a lobe of sensitivity of the antenna structure. In various embodiments, the shield structure may be layered on the inside between the antenna and the shield structure with an RF absorbing material. The aperture may be formed in part by adjustable panels and the antenna spacing from the aperture may be adjustable by adjusting an antenna mounting position within the shield. The compound antenna system may be coupled to a receiver having a threshold response based on the compound antenna system response characteristic.
