1. An IV device assembly, comprising:
a lumen forming a fluidic channel within the IV device assembly, the lumen fluidically coupled to:
a vascular access device (VAD) coupler via a funnel coupler; and
an IV device assembly coupler at a proximal end of the lumen;
a collapsible sleeve formed coaxially around the lumen and mechanically coupled to the funnel coupler;
a patency instrument provided within the collapsible sleeve, wherein a first end of the patency instrument is mechanically coupled to the funnel coupler and a second end of the patency instrument extends into the VAD coupler;
a fixed grip formed around the lumen; and
a translation handle that is movable with respect to the fixed grip and translates the patency instrument out of a distal end of the VAD coupler.
