  • 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: 8118749
    Abstract: An implant assembly is implanted in vivo within a vascular system in which a vessel divides at a furcation into two sub-vessels, each sub-vessel having a diameter smaller than the diameter of said vessel. An implant assembly is released into a vessel such as a pulmonary arterial vessel of a patient. The implant assembly has a diameter smaller than or substantially equal to the inner diameter of the vessel and larger than the inner diameter of each of the sub-vessels. The implant assembly is configured so that it moves downstream within the vessel along with the flow of blood. When the implant assembly reaches a furcation where the vessel divides, the implant assembly is too large and not sufficiently compliant to fit through either of the smaller branch vessels. The implant assembly thus lodges at the furcation, prevented from moving downstream by being too large and stiff to fit into the branch vessels, and prevented from moving upstream by the flow of blood through the arteries.
