Claim 19:
20. A catheter comprising:
a proximal tube;
an atraumatic distal end, the proximal tube and atraumatic distal end defining a longitudinal axis;
a first inductive coil comprising a first planar area and being affixed between the proximal tube and the atraumatic distal end and such that a majority of the first planar area is perpendicular to the longitudinal axis;
a second inductive coil comprising a second planar area and being affixed between the proximal tube and the atraumatic distal end and such that a majority of the second planar area is perpendicular to the longitudinal axis;
a third inductive coil comprising a third planar area such that a majority of the third planar area is perpendicular to the longitudinal axis;
a fourth inductive coil comprising a fourth planar area such that a majority of the fourth planar area is perpendicular to the longitudinal axis;
a fifth inductive coil comprising a fifth planar area such that a majority of the fifth planar area is perpendicular to the longitudinal axis; and
a sixth inductive coil comprising a sixth planar area such that a majority of the sixth planar area is perpendicular to the longitudinal axis; and
a compressible framework compressible parallel to the longitudinal axis to move the first inductive coil toward the second inductive coil, the third inductive coil toward the fourth inductive coil, and the fifth inductive coil toward the sixth inductive coil;
a catheter coupler affixed to the proximal tube and the atraumatic distal end, the catheter coupler comprising the compressible framework and structurally supporting the first inductive coil the second inductive coil, the third inductive coil, the fourth inductive coil, the fifth inductive coil, and the sixth inductive coil; and
an elongated catheter tube affixed to the proximal tube, surrounding the first inductive coil, surrounding the second inductive coil, surrounding the third inductive coil, surrounding the fourth inductive coil, surrounding the fifth inductive coil, surrounding the sixth inductive coil, surrounding the compressible framework, surrounding the catheter coupler, and extending to a proximal end of the catheter.
