| titleOfInvention | Systems, methods and devices for using passive pressure sensors to measure pressure at an inaccessible location |
| abstract | In some embodiments, systems, methods and devices for using passive pressure sensors to measure pressure at an inaccessible location are provided. In some embodiments, a system for determining pressure in a ventriculoperitoneal shunt implanted in a subject is provided, the system comprising: an acoustic source emitting signals over a range of frequencies; the ventriculoperitoneal shunt, comprising: a lumen that provides a conduit for cerebrospinal fluid between; and a passive acoustic element in a wall of the ventriculoperitoneal shunt filled with a gas, wherein the passive acoustic element emits a second signal at a resonant frequency that varies based on the pressure on the passive acoustic element; an acoustic receiver that detects the second signal and outputs an electrical signal that represents at least the resonant frequency; and a processor programmed to: receive the electrical signal; determine the pressure using the resonant frequency; and present the pressure using a display. |
