Abstract
A needle having three fluted edges, all of the same angular size. The needle presents a five sided cross-section at a tapered end. This results in easier tissue penetration, reduced cross-sectional needle area, better wound opening area performance, and minimized tissue distortion. In an alternate embodiment, the flat surface from which the taper is formed is on the inside of the needle so that the outer fluted edges are formed outside that configuration.
