| Popis: |
A passive resonant transensor that fulfills many of the criteria for accurate monitoring of intracranial pressures is reported. It is contained in a small distensible drum (0.06 ml. volume) and is easily implanted in the subdural space. It has been shown to be non-irritating to tissues even after it has been implanted for more than one year [2,3]. Since its action is passive, it is not limited to the life of one or more batteries. It is sensitive enough to record changes in intracranial pressure of 0.5 mm. H 2 O. It can be monitored immediately after implantation and has millisecond response. No fluid leakage or instrument clotting has occurred. The cranial vault can be sealed after implantation and no external connections are necessary; it is monitored by a nonattached oscillating detector placed over the scalp. Recordings can be made in the awake animal. In our studies this transensor has been implanted successfully in Rhesus monkeys. Longterm studies of spinal fluid dynamics in normal and pathologic situations are being carried out. |
