  • Patent number: 9265428
    Abstract: A wireless sensor for indicating a physical state within an environment includes a housing defining a hermetically sealed cavity. A structure located within the cavity of the housing has elements providing capacitance, the elements being arranged such that the distance and thereby the capacitance of the structure changes when a physical state of the environment changes. The structure has a resonant frequency based at least in part on the capacitance of the structure when in the presence of a fluctuating electromagnetic field. When the sensor is positioned within an environment and is subjected to a fluctuating electromagnetic field, the resonant frequency indicates the physical state of the environment.

  • Patent number: 8896324
    Abstract: A method for providing an in-vivo assessment of relative movement of an implant that is positioned in a living being is provided wherein a first assembly and a second assembly are positioned within the living being. The first assembly includes a passive electrical resonant circuit that is configured to be selectively electromagnetically coupled to an ex-vivo source of RF energy and, in response to the electromagnetic coupling, generates an output signal characterized by a frequency that is dependent upon a distance between the first assembly and the second assembly at the time of the electromagnetic coupling.

  • Patent number: 8665086
    Abstract: Aspects and embodiments of the present invention provide a system for obtaining, processing and managing data from an implanted sensor. In some embodiments, a patient or other persons can use a flexible antenna to obtain data from the implanted sensor. The flexible antenna includes at least one transmit loop and at least one receive loop. The transmit loop is adapted to propagate energizing signals to the implanted sensor. The receive loop is adapted to detect a response signal from the implanted sensor. The transmit loop includes a capacitor formed by a discontinuous area. The capacitor is adapted to allow the loop to be tuned. The flexible antenna can communicate with a patient device that collects the data from the implanted sensor, creates a data file and transmits the data file to a remote server over a network. A physician or other authorized person may access the remote server using an access device.

  • Patent number: 8237451
    Abstract: The present invention determines the resonant frequency of a sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. The system energizes the sensor with a low duty cycle, gated burst of RF energy having a predetermined frequency or set of frequencies and a predetermined amplitude. The energizing signal is coupled to the sensor via magnetic coupling and induces a current in the sensor which oscillates at the resonant frequency of the sensor. The system receives the ring down response of the sensor via magnetic coupling and determines the resonant frequency of the sensor, which is used to calculate the measured physical parameter. The system uses a pair of phase locked loops to adjust the phase and the frequency of the energizing signal.

  • Patent number: 7710103
    Abstract: The present invention determines the resonant frequency of a wireless sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. The system energizes the sensor with a low duty cycle, gated burst of RF energy having a predetermined frequency. The system receives the ring down response of the sensor and determines the resonant frequency of the sensor, which is used to calculate a physical parameter. The system uses a pair of phase locked loops to adjust the phase and the frequency of the energizing signal. The system identifies false locks by detecting an unwanted beat frequency in the coupled signal, as well as determining whether the coupled signal exhibits pulsatile characteristics that correspond to a periodic physiological characteristic, such as blood pressure.

  • Patent number: 7699059
    Abstract: The progress of a endovascular aneurysm repair can be monitored by inserting a pressure transducer sensor using a catheter into the sac during endovascular aneurysm repair and then using a small, hand-held read out device to measure pressure easily, safely, inexpensively and accurately. In one aspect a sensor is introduced into the body by the steps of folding or rolling the sensor into a cylinder, loading it into a catheter, and deploying into the aneurysm sac by allowing it to unroll or unfold, either by itself or facilitated by the incorporation of a super-elastic alloy component.
