摘要： A disclosed method determines fluid pressure inside a vessel without compromising the integrity of the vessel. A sensor is positioned in operative communication with the external wall of the vessel such that expansion of the external wall of the vessel exerts a force against the sensor that is directed substantially radially outward with respect to the vessel. A substantially radially inward force is caused to be directed against the sensor in response to the substantially radially outward force exerted by the external vessel wall. The sensor can thus be used to detect the magnitude of the substantially radially outward force.A disclosed apparatus determines fluid pressure inside a vessel without compromising the integrity of the vessel. The apparatus includes a sensor and a band operatively associated with the sensor and configured to at least partially encircle the vessel so as to retain the sensor in operative communication against the external wall of the vessel.

摘要： A method for measuring pressure within a heart includes the steps of: (1) providing a passive wireless pressure sensor having a characteristic impedance and a deflectable surface, the characteristic impedance changing in response to deflection of the deflectable surface; (2) inserting the sensor to a location within the body of a patient at which the sensor can detect pressure within the heart; (3) affixing the sensor relative to the heart; (4) interrogating the sensor with an electromagnetic field; (5) receiving a signal from the sensor corresponding to a sensed pressure; and (6) leaving the sensor in situ so that future pressure measurements can be made.

A sensor is positioned in operative communication with the external wall of the vessel such that expansion of the external wall of the vessel exerts a force against the sensor that is directed substantially radially outward with respect to the vessel. A substantially radially inward force is caused to be directed against the sensor in response to the substantially radially outward force exerted by the external vessel wall. The sensor can thus be used to detect the magnitude of the substantially radially outward force, which can be used to determine the pressure of the fluid within the vessel.
