[ What is claimed is:] [1.] A chronically implantable sensor device having tubular assembly with a first and second end and having a substantially circular passageway extending fully there through from said first to said second ends forming a passageway through said tubular assembly such that the internal surface of the passageway is coextensive with the external surface of the tubular assembly and wherein a slit extends along the axial length of the passageway from one opening of the passageway at said first end to another opening end of the passageway at said second end thus, said slit providing an access opening from said first opening end to said second opening end through said passageway wall and wherein on the interior surface of the passageway in said device, opposite from said slit, the interior surface has a substantially flat area into which a sensor is mounted.
