Self-adjusting hydrocephalus valve |
| abstract |
A system and method of accurately measuring a pressure (Pp) within a human brain using totally-implanted or partially-external hardware. The system includes a first pressure transducer configured to measure a cerebrospinal fluid pressure (Pcsf) within a ventricle of a brain, a second pressure transducer configured to indirectly measure a second pressure (Pp) within a space of the brain, and an adjustable implanted valve controller configured to calculate the effective differential pressure (Pei=PcsfâPp) between the measured pressures Pcsf and the Pp and determine whether the effective differential pressure measurement represents a true secondary pressure. |
