ABSTRACT:
A lubricated hypodermic needle of the invention includes an elongate tube with an outside surface, a proximal end, a distal end and an open bore therethrough. The needle has a hub attached to the proximal end of the needle that is used to attach the needle to a fluid handling device. The invention includes a lubricious coating applied to and adherent to the outside surface of the tube. The lubricious coating has a first layer formed from an at least partially cured organosiloxane copolymer and polydimethylsiloxane that has a viscosity greater than about 1000 centistokes. The lubricious coating has a second layer, applied as a secondary operation onto the first layer, that includes a polydimethylsiloxane having a viscosity between about 50 centistokes and about 350 centistokes.
