Abstract:
A device for location and catheterization of an area surrounding a nerve of a human or animal body comprising: a catheter (3); an electrically conducting puncture needle (1) having a metallic electrically conducting hollow needle body (10) with proximal and distal ends (13 and 12, respectively), and forming an open continuous lumen (L), from the proximal end to the distal end, having an inside diameter (d.sub.i) at least corresponding to an outside diameter (d.sub.a) of the catheter; an electrical conducting part (14) at the proximal end (13) connecting the puncture needle (1) to an electrical voltage source; a connecting element (18) connected to the proximal end (13) of the puncture needle (1) and forming a through-hole (19) in communication with the lumen (L); and an injection tubing (2) connected to the connecting element (18) in fluid communication with the through-hole (19) and the lumen (L) of the puncture needle (1), the catheter (3) extending through the through-hole (19) into the lumen (L) of the puncture needle (1) and pushed forward to the distal end (12).
