Claim Text:
1. A needle assembly apparatus, comprising: a hub; a needle cannula defining an axis and an outer surface, an entirety of the outer surface set at a constant radius with respect to the axis; and a bond between the outer surface of the needle cannula and the hub that secures the needle cannula to the hub, said bond forms a sole securement of the needle cannula with the hub, the bond configured to break entirely at the outer surface of the needle cannula for withdrawal in a distal direction of the needle cannula entirely from the hub upon application of a selected axial force to the needle cannula by axial motion between a needle gripper releaseably engaged with the outer surface of the needle cannula and a gripper engaged with the hub, the axial force being less than the tensile strength of the needle cannula, the needle gripper operable to be positioned between an engaged position releaseably engaged with the outer surface of the needle cannula and a released position disengaged from the needle cannula.
