1. A sensor comprising:

  • a base;

    a probe having a first portion proximate said base and a second portion distal said base, said probe second portion embeddable within a tissue site;

    a light emitting region of said probe second portion;

    a light collecting region comprising a detector located proximate said base and spaced from said light emitting region;

    a generally planar substrate encapsulated within said base, said substrate having a first side and a second side, said detector mounted to said substrate first side; and

    an emitter mounted on said substrate proximate said probe first portion so that light is transmitted from said emitter and reflected within said probe to said light emitting region, wherein said emitter is mounted on said substrate second side and said probe first portion extends through said substrate from said first side to said emitter on said second side whereby light transmitted from said emitting region is received at said light collecting region after passing through said tissue site.
