IMPLANTABLE MEDICAL DEVICE FOR DIAGNOSTIC SENSING
First Claim
1. An implantable medical device for use with an external detector to detect an analyte in vivo, the implantable device consisting essentially of:
- a substrate;
a plurality of discrete reservoirs located in the substrate, each reservoir having at least one opening;
a reacting component contained in each reservoir; and
at least one non-degradable barrier layer covering each reservoir opening, the barrier layer being permeable to an analyte to be detected,wherein the reacting component remains inside the reservoirs and can react with the analyte to be detected,wherein the device is adapted for implantation into the body of a patient.
