Abstract
An intraocular pressure monitoring and sensing device for implantation in an eye of a patient may include a substrate having a pressure sensor disposed on a top surface thereof and a pressure sensor cap disposed on the substrate over the pressure sensor. The pressure sensor cap may include a wall structure extending from the top surface of the substrate, the wall structure laterally surrounding the pressure sensor. The pressure sensor cap may further include a cap top situated above the pressure sensor, the cap top and wall structure together forming an interior chamber, and a chamber inlet providing fluid access to the interior chamber. At least one of the cap top and the wall structure includes a semi-permeable surface to aid in priming.
Claims15
An intraocular pressure (IOP) sensing device comprising:
- a substrate comprising a substrate chamber, an inlet, and an outlet;
- a differential pressure sensor formed from a flexible member located above the substrate, one side of the flexible member located adjacent the substrate chamber;
- and
- a pressure sensor cap disposed on the substrate over the differential pressure sensor, the pressure sensor cap enclosing an interior chamber, the pressure sensor cap comprising a semi-permeable material.
