1. An integrated patient fluid management system, comprising:
an interventional device configured to effect a change in patient fluid state by delivery of an interventional therapy;
a wireless vascular dimension monitoring sensor configured to be implanted within a patient's inferior vena cava (TVC) and to monitor changes in dimension of the IVC resulting from changes in patient fluid state; and
a control system configured to (i) communicate with the interventional device and the wireless vascular dimension monitoring sensor and (ii) modulate the delivered interventional therapy in response to TVC dimension measurements as determined by the wireless vascular dimension monitoring sensor;
wherein the wireless vascular dimension monitoring sensor is a wireless resonant circuit-based sensor;
wherein the wireless vascular dimension monitoring sensor comprises a resiliently collapsible frame member with multiple strands of individually insulated conductive wires wrapped on the resiliently collapsible frame member to form a variable inductance coil, the inductance varying in proportion to changes in dimension of the IVC.
