Zusammenfassung:A piercing device includes a tube (10) formed with a needle tip (12). The needle tip (12) includes a bevel having a bevel length (BL) that extends at a bevel angle from a base of a heel (14) to a sharp distal, radially outer edge of the needle tip (12). A reversed edge (17) is formed as a reversed edge angle on the heel (14) of the bevel. The bevel angle is an acute angle, and the reversed edge angle is an obtuse angle.
