CA 1219505

ABSTRACT OF THE DISCLOSURE A dialysis needle or the like comprises a tube with a razor edge cutting blade extending diametrically across its forward end. The blade has a generally "V" shape with a pair of razor sharp cutting edges converging forwardly from opposite sides of the tube and terminating in a needle-sharp point. A pair of diametrically opposed, smooth, tissue-spreading ribs are located in a plane normal to the cutting edges and converge forwardly from opposite sides of the tube to positions immediately rearwardly adjacent of the point. Two specific embodi- ments are described: an all-stainless-steel version; and a plastic version with a cutting blade insert.
