ABSTRACT:
A probe for measuring epidural pressure and the elasticity of brain parenchyma includes first and second chambers both formed of a thin film with a bag-shape so that they can contract/expand in response to introduction of first and second pressure transmission mediums, respectively, wherein the first and second chambers are independent of each other and provided in a stack. Thus a probe capable of accurately measuring epidural pressure and the elasticity of brain parenchyma can be provided.
