Biocompatible packaging for long-term implantable sensors and electronics

摘要

An implantable medical device is described. In one example, an implantable medical device includes an electromechanical substrate and a sensor, such as a pressure sensor, disposed on the substrate. At least a portion of the sensor is packaged by liquid encapsulation. The packaging includes a flexible outer membrane that is shaped to surround at least a portion of the sensor. The packaging also includes a hydrophobic liquid disposed between at least a portion of the pressure sensor and the flexible outer membrane. The implantable medical device can be part of a medical system that is used to monitor a medical condition or to perform a medical procedure based on the implantable medical device. Furthermore, a manufacturing method for packaging the sensor by liquid encapsulation is described.
