Abstract

The invention relates to a cannula (1) for use in body tissue and body lumens and a method for producing the cannula. The cannula is substantially rod-shaped and has varying stiffness along its length. The cannula s divided into at least a first part (2) adapted to be located within body tissue or body lumens and a second part (3) adapted to extend from the body, and the cannula comprises a super elastic material that has been treated so the bending stiffness of the first part is different from the bending stiffness of the second part .
