  • HYPODERMIC NEEDLE ASSEMBLY HAVING A TRANSITION HUB FOR ENHANCING FLUID DYNAMICS AND MICROSPHERE INJECTABILITY
    Publication number: 20130096531
    Abstract: A hypodermic needle assembly and a method of delivering a microsphere drug. A hypodermic needle assembly includes an injection needle; an injection device; and a hub defining a cavity including a transition portion having a first end and a second end between the first end and an inlet of the injection needle and having a gradually decreasing diameter from the first end to the second end, wherein the hub is coupled between the injection needle and the injection device such that the first end is in fluidic communication with an outlet of the injection device and the second end is in fluidic communication with the inlet of the injection needle, wherein the diameter of the cavity at the first end is larger than an outlet diameter of the injection device, and wherein the diameter at the second end is substantially the same as an inlet diameter of the injection needle.
