Abstract
An intraosseous needle set is provided for penetrating a target area. The intraosseous needle set includes a cannula having a first end, a second end, and a bore. The bore may accommodate an intraosseous device, such that the intraosseous device and the cannula are operable to penetrate the target area. The bore has a length extending from the second end of the cannula through the first end of the cannula. The bore has a first cross-section with a substantially constant diameter along a majority of the length and extends from the second end of the cannula toward the first end of the cannula. The bore has a second cross-section along a minority of the length and extends from the first end of the cannula toward the second end of the cannula. The second cross-section may have a different shape than the first cross-section.
