Document Type and Number:
WIPO Patent Application WO2004021959
Kind Code:
A3
Abstract:
A target nerve or nerve plexus registration point is located utilizing a nerve stimulator needle (18) positioned in a bore (14) of a carrier (12). The carrier (12) is configured with an electrically nonconductive smooth curved surface (16) at a distal end of the bore. The needle tip (28) is fixed in an operative cutaneous electrode position and the smooth curved surface (16) of the carrier (12) is forced against and compresses the epidermis, corium and subcutaneous tissue and traverses cutaneous surfaces to locate a target nerve or nerve plexus without physical penetration by the needle tip (28). The needle (18) is then inserted at the located point.
