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