Abstract
A tissue collection needle with a hollow interior provides two opposing tips with beveled edges on facets that drive tissue toward the hollow interior where the tissue can be gathered and severed from surrounding tissue as the needle advances through a biological specimen. The points and bevels are advantageously formed from a minimal number of cuts amenable to rapid fabrication from readily available hollow needle stock.
