1. An apparatus for displaying representations of parameters of an inflatable body and/or expandable body disposed proximate to a portion of a tissue, the inflatable body and/or expandable body comprising a plurality of sensors coupled to at least a portion of the inflatable body and/or expandable body, the apparatus comprising:

  • a user interface;

    at least one memory to store processor-executable instructions; and

    at least one processing unit communicatively coupled to the at least one memory, wherein, upon execution of the processor-executable instructions, the at least one processing unit;

    controls the user interface to display at least one representation of the parameters, the at least one representation comprising;

    (A) a first representation of a state of the inflatable body and/or expandable body, the first representation comprising;

    (i) a first form indicator to indicate that the inflatable body and/or expandable body is in an inflated and/or an expanded state;

    or(ii) a second form indicator to indicate that the inflatable body and/or expandable body is in a deflated and/or a collapsed state; and

    (B) a second representation of a state of at least one sensor of the plurality of sensors, the second representation comprising;

    (i) a first activation indicator to indicate that the at least one sensor of the plurality of sensors measures a signal below a threshold value;

    or(ii) a second activation indicator to indicate that the at least one sensor of the plurality of sensors measures a signal above or about equal to the threshold value,wherein the second representation is indicative of a magnitude of an instantaneous velocity.
