Abstract
A syringe and needle assembly having a piston that is formed to engage and retract the needle assembly into the syringe barrel. The piston includes a spring member that is elastically deformed by the attachment of the piston to the needle assembly. The spring member causes the needle assembly to be spring biased into a canted position so that, once retracted into the syringe barrel, the needle assembly cants to an inoperable position.
