Abstract
A flexible catheter shaft suitable for inserting into a body of a patient comprising a deflectable, high torque transmission assembly of a slit tubular element that has either a plurality of rows of slits with anchors or at least one continuously spiraling slit on said slit tubular element and has sufficient bending and torque properties ensuring that a substantial fraction of the bending, rotational and displacement forces provided along said flexible catheter shaft are translated to bending, rotational and displacement forces at a distal end of said flexible catheter shaft.
