Abstract
A trocar has an elongate body and a tissue-penetrating tip. One or more radially extending blade(s) are provided near the tissue-penetrating tip of the trocar body so that they automatically open as the trocar is advanced through tissue. The blades will enlarge the penetration which was formed by the tip of the trocar.
