Wireless flow measurement in arterial stent
First Claim
1. A blood flow sensing system, comprising:
- a sensor coupled to at least one antennae, wherein said sensor measures a flow of blood within a blood vessel when stimulated with a short range energy field detectable by said at least one antennae;
a transmitter and a receiver, wherein said transmitter and said receiver can transmit said short range energy field to said at least one antennae of said sensor, wherein said receiver can receive data transmitted from said sensor via said at least one antennae; and
a stent integrated with sensor, wherein said stent comprises a small diameter cylinder that props open a blood vessel and wherein said stent is moveable into said blood vessel to form a rigid support for holding said blood vessel open.

Abstract
A blood flow sensing system is disclosed, including a sensor coupled to an antenna, such that the sensor measures a flow of blood within a blood vessel when stimulated with a short range radio frequency energy field detectable by the antenna. Such a system additionally can include a transmitter and receiver unit (i.e., a transmitter/receiver), which can transmit the short range radio frequency energy field to the antenna of the sensor. The transmitter and receiver unit can also receive data transmitted from the sensor via the antenna. Such a system additionally includes a stent integrated with sensor, wherein the stent comprises a small diameter cylinder that props open a blood vessel and wherein the stent is moveable into the blood vessel to form a rigid support for holding the blood vessel open in order to measure the flow of blood within the blood vessel.
