Abstract
A stylet unit which can be introduced into a narrow, hollow, flexible component, such as a hollow electrode cable for a heart stimulator, to stiffen the component and bend its distal end section, is in the form of a double stylet combination with a flexible stylet shell and an internal stylet, movably arranged inside the shell, with a pre-curved distal end section, whose radius of curvature is on a first side of the stylet. In an area before the pre-curved end section, the stylet has a pre-shaped stylet section with a pre-shaped stylet section whose radius of curvature is on the side of the stylet opposite the first side on which the end section's radius of curvature lies.
