Patent

CA 2616037

The present invention relates to devices and systems that alter intracranial compliance, cerebral blood flow and/or intracranial pressure pulsatility/waveform by oscillating the contraction and expansion of a compressible composition within the cranial or spinal cavities such that they increase intracranial capacity. The contraction and expansion of the compressible composition in the oscillating compliance devices can be due to an individual's intracranial pressure, the result of the expansion and compression of a reservoir which is mediated by the contractility of the heart or driven by a pump gaited to a biorhythm. The invention also relates to methods for protecting an individual's brain from abnormal arterial pulsations and for altering an individual's cerebral blood flow using the devices and systems of the invention.

Dispositifs et systèmes modifiant la capacité intracrânienne, la circulation sanguine cérébrale et/ou la pulsatilité de la pression intracrânienne par soumission à une oscillation entre contraction et dilatation d'une composition compressible à l'intérieur des cavités crânienne et vertébrale, de façon à augmenter ladite capacité. Ces contractions et dilatations de la composition compressible peuvent être dues à la pression intracrânienne résultant de la dilatation et de la compression d'un réservoir sous l'effet de la contractilité cardiaque ou de l'entraînement d'une pompe adaptée à un rythme biologique. L'invention concerne également des procédés servant à protéger le cerveau contre des pulsations artérielles anormales et à modifier la circulation sanguine cérébrale au moyen de ces dispositifs et de ces systèmes.
