Abstract
A miniature, low power electronic pressure sensor with a first, oil-filled chamber to protect its microelectromechanical systems (MEMS) pressure sensitive membrane and a second chamber filled with saline or body fluids connected by tube into an organ in the body, such as an eyeball, that needs pressure sensing, is described. The tube carries pressure from a sensitive area within the organ to the electronic pressure sensor. The pressure sensor may communicate wirelessly with external readers and pass data to a server or other computer. Running alongside the tube is another tube for draining and pressure relief. The tubes, or cannulas, can share an opening into the organ in order to minimize the number of holes needed. The tubes may be molded into a single oval cross section, combined coaxially, or share a lumen for a portion that enters the wall of an organ so as to promote healing.
