1. An articulation segment of a catheter for selectively bending the catheter in a plurality of planes, the articulation segment comprising:

  • a hollow tube having a wall and defining a longitudinal axis, the tube being formed with a plurality of first slits cut through the wall in respective planes substantially perpendicular to the axis, with each first slit extending azimuthally in an arc partway around the axis from a first end to a second end and defining a center midway therebetween, and wherein the respective centers of the first slits are aligned along a first substantially helical path, the tube being further formed with a plurality of second slits cut through the wall in respective planes substantially perpendicular to the axis, with each second slit extending azimuthally in an arc partway around the axis from a first end to a second end and defining a center midway therebetween, and wherein the respective centers of the second slits are aligned along a second substantially helical path, with said second helical path being substantially diametrically opposite said first substantially helical path relative to said axis to allow for the selective bending of the catheter.
