Abstract
A unitary multilumen cranial bolt for use in multimodal monitoring of a plurality of physiological parameters in brain tissue incorporates a plurality of lumens, each lumen directing a catheter borne sensor through a bore hole in the cranium and into brain tissue of a patient. The lumens are configured to cause the catheters to splay outward as they enter the cranial cavity and reach their intended depth of penetration. Each lumen is associated with a guide. The guides are adapted for use with introducers that enable fragile and/or flexible sensors to be introduced into brain tissue. Each catheter borne sensor can be positioned and repositioned within brain tissue independently of all other sensors.
