1. An implantable pressure and force sensing apparatus, for measuring the mechanical behavior of the soft tissue of the body, comprising:

  • a main guide cannulae;

    said main guide cannulae having an alignment key positioned at the lower end of said main guide cannulae;

    said main guide cannulae further having a direction indicator at the upper end of said cannulae;

    retractable centerline cutting and positioning means;

    tubular means comprising means that fit over said retractable centerline cutting and positioning means;

    said tubular means having at least one sensing means attached thereto;

    said tubular means having a protective pocket for said at least one sensing means;

    said tubular means further having a longitudinal slot for receiving said alignment key of said main guide cannulae, and extends from one end of said tubular means to the opposite end of said tubular means;

    said tubular means further having an alignment projection means located at the upper end of said tubular means for maintaining said tubular means in the proper orientation within tissue;

    said upper end of said tubular means being in close replaceable contact with the lower end of said main guide cannulae for the purpose of buttressing the tubular means during implantation; and

    said tubular means further having an enlarged tapered section at the end opposite said upper end for preventing said tubular means from backing out of the tissue.
