Abstract
A catheter and introducer needle assembly with needle shield that is connected to the needle hub by a pleated tether. The tether defines a plurality of holes therein to allow the introducer needle to extend through the tether. Each hole defines a longitudinal dimension and a radial dimension such that the radial dimension is less than the longitudinal dimension. This configuration improves the tensile strength of the tether. The tether prevents unwanted proximal movement of the needle with respect to the needle shield once the needle has been withdrawn into the needle shield.
