An assembly for the epidural or peripheral nerve blockade

摘要

It is a an assembly for the epidural or peripheral nerve blockade is described, in which a flexible catheter (20) a stimulation tip (22) for the localization and positioning of the catheter tip has by electrical stimulation. In the catheter (20) is a stiffening there (40) is insertable. The axial position of the stiffening drins (40) is in the catheter (20) is selected in such a way that a distal end portion (b) of the catheter (20) and remains flexible stiffens unavoidable.
