Title:
ELECTRODE FOR INTRAOPERATIVE NERVE STIMULATION
Document Type and Number:
WIPO Patent Application WO/2012/063189
Kind Code:
A2
Abstract:
The invention relates to an electrode (2) for intraoperative nerve stimulation of the vagus nerve (26), said electrode being suitable for continuous neuromonitoring during an operation, in particular for neuromonitoring of the vagus nerve (26) during thyroid operations. The electrode comprises a strip-shaped electrode carrier (4) made of elastic material and at least one electrically conductive contact surface (12), which can be connected to a signal transmitter and/or signal receiver by means of a signal transmission medium (16) and which touches the vagus nerve (26) at a part of the circumference thereof during application. The electrode (2) is characterized by a first sub-section (6) having a plastically deformable material, so that during application the electrode carrier (4) can be shaped at the first sub-section (6) onto a vessel wall of a first blood vessel (22) extending parallel to the vagus nerve (26) and surrounds said blood vessel (22) in a hook shape in order to fasten the electrode (2), and by a second sub-section (10), which can be laid around the vagus nerve (26) in a loop shape with curvature opposite the first sub-section (6). The invention further relates to an electrode (2), which is characterized in that the electrode carrier (4) has a pre-shaped section having a bend at least at the head end (5) of the electrode carrier, so that during application the electrode carrier (4) surrounds a vessel wall of a blood vessel (22) extending parallel to the vagus nerve (26) in a hook shape in order to fasten the electrode.
