Abstract
A stylet unit, which can be introduced into a hollow, flexible component, such as an electrode cable, to stiffen the component and to bend a distal end section is formed by a double stylet combination of a flexible tubular stylet shell and an internal stylet, movably arranged inside the shell's channel, with a pre-curved distal end section. This end section can be set at a retracted internal position inside the stylet shell or at an exposed position outside the shell. The internal stylet's pre-curved distal end section is made of a memory metal and has a radius of curvature which varies longitudinally along the end section. The end section can be in the shape of a spiral, and the memory metal can be made of a nickel-titanium alloy.
