<p>PROBLEM TO BE SOLVED: To confirm the rotation angle and circumferential position of an electrode only by X-ray projected images captured at each time point.SOLUTION: A nerve stimulation lead 1 comprises: a conductive lead body 2 insertable into a body cavity and introducing a stimulation pulse; and an electrode body 3 fixed to a tip of the conductive lead body 2. Fixed to the electrode part 3 are: an electrode 5 emitting the stimulation pulse introduced by the conductive lead body 2; and markers 6, 7 which are made from an X-ray impermeable material, and which when the electrode part 3 is rotated about the longitudinal axis P of the conductive lead body 2, change the shape of an image projected in one direction crossing the longitudinal axis P, based on the rotation angle.</p> |
