Abstract

Fluid flow monitoring system. Structure for implantation in association with vascular tissue is provided. Fluid flow monitoring apparatus is supported on the structure to generate a signal related to fluid flow. A wireless transmitter supported on the structure transmits the signal outside the body. A reader external to the body is provided for wirelessly energizing the monitoring apparatus and transmitter and for receiving the transmitted signal. The external reader also displays fluid flow velocity and/or rate.
