1. A system for measuring constriction pressure within a body lumen, said system comprising:

  • an elongated cylindrical core member;

    a first array of substantially parallel, electrically-conductive strips substantially conformed to at least a portion of said elongated cylindrical core member;

    a second array of substantially parallel, electrically-conductive strips, disposed transverse to and in overlapping relationship with said first array of substantially parallel electrically conductive strips, and substantially conformed to at least said portion of said elongated core member, so as to provide with said first array a plurality of pressure transducer regions around the circumference and along the axis of said core member; and

    means, disposed between said first and second arrays at said pressure transducer regions, for defining a predetermined, measurable parameter at each of said regions between the corresponding electrical conductive strips of the first and second arrays such that the parameter varies as a function of a force applied to each of said regions so that constriction pressure within a body lumen can be measured.
