1. A method for determining fluid pressure inside a vessel without compromising the integrity of the vessel, comprising the steps of:

  • positioning a sensor 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;

    causing a substantially radially inward force to be directed against the sensor in response to the substantially radially outward force exerted by the external vessel wall which further comprises the step of inserting the sensor between the external wall of the vessel and an adjacent body of tissue; and

    using the sensor to detect the magnitude of the substantially radially outward force.
