BIOCOMPATIBLE PACKAGING FOR LONG TERM IMPLANTABLE SENSORS AND ELECTRONICS

摘要

An implantable medical device is described. In an example, the implantable medical device includes an electromechanical substrate and sensor, such as a pressure sensor, disposed on the substrate. At least a portion of the sensor is packaged via a liquid encapsulation. The packaging includes a shaped flexible outer membrane that surrounds at least the portion of the sensor. The packaging also includes a hydrophobic liquid disposed between at least the portion of the pressure sensor and the flexible outer membrane. The implantable medical device can be a part of a medical system used for monitoring medical conditions or performing medical operations based on the implantable medical device. Additionally, manufacturing methods are described for packaging the sensor in a liquid encapsulation.
