1. A stent, comprising:
- a wire tube; and
at least one pressure sensor in electrical contact with the wire tube, the pressure sensor including a diaphragm in communication with a reservoir of liquid, a channel in fluid communication with the reservoir of liquid, and a plurality of pairs of electrodes disposed on opposite sides of the channel, wherein deflection of the diaphragm causes fluid to move from the reservoir into the channel.
