Abstract
Intraocular pressure sensors, systems, and methods of use. Implantable intraocular pressure sensing devices that are hermetically sealed and adapted to wirelessly communicate with an external device. The implantable devices can include a hermetically sealed housing, the hermetically sealed housing including therein: an antenna in electrical communication with a rechargeable power source, the rechargeable power source in electrical communication with an ASIC, and the ASIC in electrical communication with a pressure sensor.
Claims20
An implantable device with a biocompatible coating, comprising:
- a pressure sensing element;
- and
- a coating disposed on an outer surface of the implantable device, the coating comprising an inner layer disposed on the outer surface, and an exterior layer exposed to an ambient environment,
- wherein the inner layer has an inner cross link density, and the exterior layer has an exterior cross link density that is lower than the inner cross link density.
