ABSTRACT:
Puncturing and catheterizing device for the human or animal body with a metallic puncture needle and a cannula which surrounds the puncture needle in the region between its point and rear end and through which, after the puncture needle has been pulled out, a longer guide-wire can be inserted into the body, which then, after the cannula has also been pulled out, serves as a guide for a catheter to be inserted. The puncture needle 3 is electrically conductive from its point 1 to its end projecting out of the cannula 9 and is equipped with an electrical connecting piece 5 at the rear end (FIG. 1 ).
