摘要： 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. Alternatively, the implant assembly has a diameter greater than a vessel and compliance characteristics such that, upon release, the implant assembly travels down a narrowing vessel until an interference fit is created between the anchor structure and the vessel wall, thereby preventing further distal movement.

摘要： A pressure cavity is durable, stable, and biocompatible and configured in such a way that it constitutes pico to nanoliter-scale volume. The pressure cavity is hermetically sealed from the exterior environment while maintaining the ability to communicate with other devices. Micromachined, hermetically-sealed sensors are configured to receive power and return information through direct electrical contact with external electronics. The pressure cavity and sensor components disposed therein are hermetically sealed from the ambient in order to reduce drift and instability within the sensor. The sensor is designed for harsh and biological environments, e.g. intracorporeal implantation and in vivo use. Additionally, novel manufacturing methods are employed to construct the sensors.

摘要： A coupling loop or antenna is provided that can be used with a system that 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. A cable attached to the coupling loop provides maximum isolation between the energizing signal and the sensor signal by maximizing the distance between the coaxial cables that carry the signals and maintaining the relative positions of the coaxial cables throughout the cable assembly.

摘要： 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.

摘要： 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.

摘要： A sensor has a sensor housing defining a cavity therein. A first wall partially defining the cavity is deflectable under a physiologically relevant range of pressures. An integrated circuit chip bearing electronics is fixedly mounted within the cavity. A capacitor comprises first and second capacitor plates in generally parallel, spaced-apart relation. The first capacitor plate is physically coupled to the deflectable wall so as to move as the wall deflects, and the second capacitor plate is carried by the chip. The second capacitor plate is in electrical communication with the input pad of the chip.
