Abstract: A neuromodulation probe includes a body and at least one coil set. The body has a first axis and a length along the first axis. The at least one coil set includes at least one coil, and the at least one coil is formed by winding spirally a conductive wire plural times about a second axis inside the body or on an outer surface of the body. The second axis is parallel to the first axis. The at least one coil has two opposite wire ends for providing an electric current to flow in or out of the at least one coil.

Abstract: A medical material needle, applicable for detection and positioning by an ultrasound, includes a needle body having a three-layer structure. The three-layer structure includes an outer structure, an inner structure, and a middle structure disposed between the outer structure and the inner structure. The outer structure and the middle structure have different characteristic acoustic impedance with respect to the ultrasound, the inner structure and the middle structure have different characteristic acoustic impedance with respect to the ultrasound, and at least one of the outer structure, the middle structure and the inner structure is provided with a dimension in at least one direction less than a wavelength at a frequency of the ultrasound in water.
