Abstract
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 ).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A puncturing and cathetering 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 guidewire 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, wherein the puncture needle (3,3') 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; 31,33) at the rear end and means for connecting the electrical connecting piece to an electrical source.
Claim 2
Dependent Claim
120 words
A puncturing and cathetering 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 guidewire 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, wherein the puncture needle (3,3') 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; 31,33) at the rear end and means for connecting the electrical connecting piece to an electrical source.
Claim 3
Dependent Claim
