ABSTRACT:
A syringe stopper for use in a syringe barrel having a substantially cylindrical body comprises a piston-like stopper body for slidable fluid-tight engagement inside the barrel of the syringe. The body includes a distal end, a proximal end and a longitudinal axis therethrough. A distally directed, conically-shaped projection is positioned on the distal end of the stopper body. At least one elongate discontinuity, running along the conically-shaped projection, is provided. The discontinuity includes a first end on the conically-shaped projection and extends radially outwardly therefrom to a second end, as viewed from the distal end of the stopper. The discontinuity may be in the form of a raised rib or a recessed groove.
