Abstract

A cannula (1) of changeable length and shape, built up of consecutively arranged and touching each other elements (2), each of which occupies part of the cannula length, in which the change in the length and shape is effected by adding or removing from the end of the cannula elements with folding width, while the transport of the free and unlinked in the cannula wall elements towards its growing end or in the opposite direction is effected in a folded state through the interior of the cannula.
