Medical device for analyte monitoring and drug delivery
First Claim
1. A method of detecting and/or treating a disease in a patient comprising:
- A) contacting an ingestible medical device with a bodily fluid by administering said device to a patient, said device having an exterior surface and an interior surface and comprising;
a) a microarray of miniature test sites configured to fluidically communicate with the bodily fluid of the patient, wherein said microarray comprises a plurality of the test sites on a continuous surface, each site of said plurality comprising a polypeptide bioactive agent immobilized thereon to effect an interaction with a disease marker suspected to be present in the bodily fluid;
b) a reservoir comprising a therapeutic agent;
c) an optical microarray scanning device that is configured to optically detect signals from the plurality of test sites on the continuous surface, wherein the signals are indicative of a physical parameter indicative of the disease marker based on an interaction between the disease marker and said polypeptide bioactive agents at said plurality of test sites;
d) a biometric recognition device that is configured to compare said physical parameter data with an analyte interaction profile;
e) a therapeutic agent releasing device that is configured to control release of at least one therapeutic agent from said reservoir;
f) an interface device that is configured to facilitate communication between said microarray scanning device and said biometric recognition device; and
g) a biocompatible polymer coating, coated on the exterior surface of said ingestible medical device, facilitating said device to pass through an intestinal tract; and
B) operating said ingestible medical device to obtain the physical parameter indicative of the presence of said disease; and
optionallyC) releasing said therapeutic agent to said patient.

Abstract
The invention relates to an ingestible, implantable or wearable medical device comprising a microarray which comprises a bioactive agent capable of interacting with a disease marker biological analyte; a reservoir which comprises at least one therapeutic agent and is capable of releasing the therapeutic agent(s) from the medical device; and a plurality of microchips comprising a microarray scanning device capable of obtaining physical parameter data of an interaction between the disease marker biological analyte with the bioactive agent; a biometric recognition device capable of comparing the physical parameter data with an analyte interaction profile; optionally a therapeutic agent releasing device capable of controlling release of the therapeutic agent from the reservoirs; an interface device capable of facilitating communications between the microarray scanning device, biometric recognition device and the therapeutic agent releasing device; and an energy source to power the medical device. Specifically, the invention relates to a medical device capable of detecting an analyte in a bodily fluid comprising at least one microneedle capable of obtaining a sample of a bodily fluid, a first microchannel through which the sample flows and is in fluid communication with the at least one microneedle, a second microchannel in fluid communication with the first microchannel, through which a buffer flows, wherein the second channel comprises a microarray with a bioactive agent, a microarray scanning device to detect an interaction between the bioactive agent and the analyte in the bodily fluid; and an interface device.
