Abstract
An assembly for facilitating ultrasonic visualization of positioning of a needle inserted into tissue includes a needle that is inserted into a sheath to define a transport channel between an outer surface of the needle and an inner surface of the sheath for transport of a fluid that is introduced into the sheath. The transport channel includes features that induce formation of ultrasonically visible features from the fluid. These features exit from the end of the sheath where they can be detected via ultrasonic imaging.
