Abstract
A needle having ten edges, forming a star-shaped cross-section. The needle also presents a tapered end. With reduced cross-sectional area, the improved needle results in easier tissue penetration, better wound opening area performance, and minimized tissue distortion. In an alternate embodiment, wound opening is further reduced by creating an eight-sided, star-shaped needle cross-section.
