Vascular access device assembly facilitating single-handed patency probe advancement
An IV device assembly may include a lumen forming a fluidic channel within the IV device assembly. The lumen may be 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. The IV device assembly may also include one or more of the following: a collapsible sleeve formed coaxially around a first portion of the lumen and mechanically coupled to the funnel coupler, a patency instrument formed along a second portion of the lumen within the collapsible sleeve and into the VAD coupler, a translation handle that translates the patency instrument out of a distal end of the VAD coupler, and a fixed grip formed around the lumen to maintain a position of the IV device assembly relative to the translation handle.

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.
2. The IV device assembly of claim 1 , wherein the patency instrument passes through a channel formed in the translation handle and passes through the funnel coupler and into the VAD coupler.
3. The IV device assembly of claim 1 , wherein the lumen is offset from a fluid axis of the VAD coupler.
4. The IV device assembly of claim 1 , further comprising a catheter coupled to the VAD coupler.
5. The IV device assembly of claim 1 , further comprising a blood sample access device mechanically coupled to the IV device assembly coupler to receive a blood sample via the IV device assembly.
6. The IV device assembly of claim 1 , where in the patency instrument is a guidewire that comprises a porous distal end.
7. The IV device assembly of claim 1 , wherein the collapsible sleeve further comprises a coil spring that creates a space between the lumen and bias the translation handle towards a proximal end of the IV device assembly.
8. 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 patency instrument formed along a length of the lumen, wherein a first end of the patency instrument is mechanically coupled to the funnel 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, wherein the patency instrument passes through a channel formed in the translation handle and passes down and into the VAD coupler.
9. The IV device assembly of claim 8 , wherein the lumen is offset from a fluid axis of the VAD coupler.
10. The IV device assembly of claim 8 , further comprising:
a catheter coupled to the VAD coupler; and
a blood sample access device mechanically coupled to the IV device assembly coupler to receive a blood sample via the IV device assembly.
11. The IV device assembly of claim 8 , wherein the patency instrument is a guidewire that comprises a porous distal end.
