    Abstract: In various examples, an apparatus includes a needle assembly including an outer cannula including a tubular sidewall disposed around a lumen. At least a portion of the sidewall includes an exterior including a polymeric material configured to inhibit skiving of an interior of a dilator with movement of the outer cannula within the dilator. An inner cannula is disposed within the lumen and is selectively slidable with respect to the outer cannula. A handle is disposed at a proximal portion of the needle assembly. The handle includes a first handle portion coupled to and movable with the outer cannula. A second handle portion is coupled to and movable with the inner cannula, wherein the first handle portion is selectively movable with respect to the second handle portion to extend a distal end of the inner cannula from within the lumen of the outer cannula.
