1. An anatomical-positioning apparatus for acquiring mechanical data from a mammalian tissue to facilitate determining type of said tissue and transition between different tissues and cavities, comprising:

  • a) a cannula having a tip at the distal section of said cannula;

    b) an expandable device having a contracted form size, when in a contracted state, and an expanded form size, when in an expanded state, wherein said expanded form size is substantially larger than said contracted form size;

    c) an introducer, having a longitudinal axis and a distal end, facilitating the introduction of said expandable device into said mammalian tissue, said expandable device being in said contracted state;

    d) an expanding-mechanism for expanding and contracting said expandable device; and

    e) a sensor for measuring physical parameters associated with said expandable device, to thereby provide sensed data, while said expandable device exerts pressure onto portions of said mammalian tissue, to thereby facilitating determining the type of tissue that is in contact with said expandable device and to determine a transition between different tissues and cavities,wherein said expandable device is securely attached to said tip of said cannula or on the external circumference of said cannula, proximal to said tip of said cannula; and

    wherein when said expandable device expands from said contracted state to said expanded form size, said expandable device is disposed outside said introducer, and a blunt contact surface is formed at the external surface of said expanded expandable device.
