Patent ID: 6926674

Claim:
A sensor and guide wire assembly having a distal end and a proximal end comprising: a core wire having a distal end and a proximal end; a sensor mounted in the distal end region of said core wire; a tube enclosing said core wire over at least a fraction of a length of said core wire such that said core wire extends out from a distal end of said tube; a first enclosure arranged to enclose a first portion of said core wire extending out from said distal end of said tube, said first enclosure being located nearer to said proximal end of said core wire than said sensor; a second enclosure arranged to enclose a second portion of said core wire extending out from said distal end of said tube, said second enclosure being located nearer to said distal end of said core wire than said sensor; wherein said guide wire further comprises at least two electrodes for conductance measurement, and said at least two electrodes are electrically insulated from each other.
