Highly Reliable Ingestible Event Markers and Methods for Using the Same
First Claim
Patent Images
1. A highly reliable event marker comprising:
- a support;
a control circuit physically associated with the support to control the highly reliable event marker;
a first electrochemical material physically associated with the support and electrically coupled to the control circuit;
a second electrochemical material electrically coupled to the control circuit and physically associated with the support at a location different from the location of the first material, such that the first and second electrochemical materials are electrically isolated from each other; and
a membrane physically associated to the support and positioned relative to the first electrochemical and second electrochemical materials to generate a virtual dipole length larger than an actual dipole length defined by the first and the second electrochemical materials.

Abstract
Ingestible event markers having high reliability are provided. Aspects of the ingestible event markers include a support, a control circuit, a first electrochemical material, a second electrochemical material and a membrane. In addition, the ingestible event markers may include one or more components that impart high reliability to the ingestible event marker. Further, the ingestible event markers may include an active agent. In some aspects, the active agent, such as a pharmaceutically active agent or a diagnostic agent may be associated with the membrane.
