ABSTRACT:
A needle assembly for the sterile and physical protection of a needle cannula and a method for making the needle cannula is described. A removable sealing tube is integrally attached to one end of a holder which fixedly retains the needle cannula. A removable needle protector is integrally attached to the other end of the holder. The sealing tube, holder and protector define a unitary piece which encases the needle cannula. To make the needle assembly, an insert assembly including an annular die, the needle cannula and an outer cannula is positioned in a forming cavity. The forming cavity is then filled with molten plastic which upon cooling forms the unitary piece. The forward and rearward ends of the unitary piece are then sealed.
