Method for integrating facilitated blood flow and blood analyte monitoring
First Claim
1. A method for the integrated facilitization of blood flow and monitoring of blood analyte concentration comprising:
- implanting a stent configured for implantation into a cardiovascular system of a user'"'"'s body, the stent having a longitudinal centerline and configured to facilitate blood flow, the stent having attached thereto a continuous blood analyte determination module of a blood analyte monitoring system;
disposing a reader module of the blood analyte monitoring system external to the user'"'"'s body and in proximity to a portion of the user'"'"'s skin layer;
monitoring a blood analyte concentration using the reader module and the continuous blood analyte determination module,wherein the monitoring step is accomplished by;
emitting an RF carrier signal from a first antenna of the reader module toward the stent;
receiving the RF carrier signal at a reflection antenna of the continuous blood analyte determination module;
reflecting a modulated signal by the reflection antenna wherein the modulated signal is encoded with a blood analyte concentration determined by a sensor of the continuous blood analyte determination module;
receiving the modulated signal by a second antenna of the reader module; and
decoding the analyte concentration from the modulated signal by the reader module; and
wherein the first antenna and second antenna are configured such that an RF carrier signal angle β and
a modulated signal angle α
are both less than about 30 degrees with respect to the stent center line.

Abstract
A method for the integrated facilitization of blood flow and monitoring of blood analyte concentration (for example, blood glucose concentration) includes implanting a stent configured to facilitate blood flow into a cardiovascular system of a user'"'"'s body with the stent having attached thereto a continuous blood analyte determination module of a blood analyte monitoring system. The method also includes disposing a reader module of the blood analyte monitoring system external to the user'"'"'s body and in proximity to a portion of the user'"'"'s skin layer and monitoring blood analyte concentration via (i) emitting an RF carrier signal from the reader module toward the stent; (ii) receiving the RF carrier signal at a reflection antenna of the continuous blood analyte determination module; (iii) reflecting a modulated signal by the reflection antenna with the modulated signal being encoded with a blood analyte concentration determined by a sensor of the continuous blood analyte determination module; (iv) receiving the modulated signal by the reader module; and (v) decoding the analyte concentration from the modulated signal by the reader module.
