Abstract:
1. An implantable pressure monitor comprising: a substantially rigid chip including: a substantially rigid substrate that: a flexible filler material located throughout space between the chip and the substrate except beneath the aperture, thereby leaving the pressure sensors exposed, such that (a) the flexible filler material connects the chip to the substrate, and (b) the distal end of the chip is connected to the substrate by only the flexible filler material; a wire that: an antenna electrically connected to the wire, emitting radiofrequency electrical signals conveying the output signals, and receiving radiofrequency power; a biocompatible sheath that encapsulates the chip, substrate, filler, wire, and antenna and is sufficiently flexible to transmit pressure exerted on the sheath exterior through the sheath; and a pressure-transferring medium extending from the sheath, through the aperture, and to the pressure sensors, thereby transferring pressure exerted on the sheath exterior to the pressure sensors.
