초록 ▼

An apparatus for continuous monitoring of cerebral blood flow and intracranial pressure for substantially the same local region of cerebral tissue. A combined probe includes an elongated housing member that contains an ICP probe and a single optical fiber LDF microprobe. The LDF probe and the ICP probe are situated adjacent to each other within the elongated housing member, and preferably their respective intracranial ends are flush with the distal end of the elongated housing member. In addition, the combined probe is adapted to cooperate with an intracranial access system for securing the combined probe, and mitigating movement artifacts. In another embodiment, a combined probe includes a tissue oxymetry probe thus providing both metabolic and hemodynamic information for the same locus of cerebral tissue, and may be used for measuring a local cerebral metabolic rate. Another embodiment of the present invention provides a probe structure that includes a plurality of LDF microprobes for measuring CBF at spatially separate locations. In accordance with the present invention, a system and methods based on multi-modality monitoring, including monitoring of CBF and ICP for the same locus of cerebral tissue, are provided for measuring and assessing physiological processes and parameters including: autoregulation, cerebral vascular resistance (CVR), and carbon dioxide (CO2) reactivity.

A probe, having a proximal and distal end, for intracranial monitoring of pressure and blood flow in a locus of a tissue medium proximately located at the distal end, said probe comprising: a first optical conductor, having one end located at said distal end and an opposite end located at said proximal end, that guides radiation to said distal end and guides radiation scattered from said tissue medium to said proximal end for providing a first indicative of the blood flow in the locus of the tissue medium; and a second optical conductor, having one end including a pressure responsive means located at said distal end, adapted for generating an second optical signal at an opposite end located at said proximal end, said optical signal indicative of said pressure in the locus of the tissue medium; wherein said first signal indicative of the blood flow in the locus of tissue medium and second optical signal indicative of said pressure in the locus of the tissue medium are measured substantially simultaneously and continuously wherein sections of respective said optical conductors extending from said respective one ends of said first and second optical conductors, are movable together, providing an elongated integral section.
