Abstract
An apparatus includes an implantable device, such as a chronically implantable device that has a device body. One or more chemical sensors are coupled with the device body. A drug eluting substance is disposed at a location including at least one of on, directly adjacent, or near the one or more chemical sensors, where the drug eluting substance prevents fibrotic growth on the one or more chemical sensors.
