Vascular access system embodiments can be configured to remove gas and a piercing member from a catheter assembly. In some embodiments, vascular access systems can remove gas and at least a portion of a piercing member concurrently or simultaneously. In some embodiments, vascular access systems can remove gas before removing at least a portion of a piercing member. In several embodiments, a vascular access system can include a first barrel configured to remove gas and a second barrel configured to retract a piercing member.
1. A vascular access system for placement of a catheter within a patient's blood vessel, the vascular access system comprising: a catheter hub;a fluid passage positioned at least partially within the catheter hub;a catheter coupled to the catheter hub;a retractable needle coupled to the catheter hub
1. A vascular access system for placement of a catheter within a patient's blood vessel, the vascular access system comprising: a catheter hub;a fluid passage positioned at least partially within the catheter hub;a catheter coupled to the catheter hub;a retractable needle coupled to the catheter hub;a connector coupled to the catheter hub; anda tube extending from the catheter hub to the connector, wherein the tube allows the connector to be positioned in different locations relative to the catheter hub,wherein the connector includes a first position in which a path through the connector is open and a second position in which a path through the connector is closed, andwherein a flow controller is coupled to the connector and is configured to transition the connector from the first position to the second position. 2. The vascular access system of claim 1, wherein a portion of the flow controller extends into the connector. 3. The vascular access system of claim 1, wherein a portion of the flow controller overlaps at least a portion of the connector on an outside of the connector. 4. The vascular access system of claim 1, wherein at least a portion of the tube is configured to extend toward the patient. 5. The vascular access system of claim 1, wherein the connector is configured to connect the catheter hub to a fluid extraction assembly to place the catheter hub in fluid communication with the fluid extraction assembly. 6. The vascular access system of claim 5, wherein the fluid extraction assembly comprises a fluid reservoir and a plunger. 7. The vascular access system of claim 6, wherein the fluid extraction assembly is configured such that sliding the plunger proximally expands the fluid reservoir and wherein the plunger is coupled to the retractable needle such that sliding the plunger proximally causes the retractable needle to retract proximally with respect to the catheter. 8. The vascular system of claim 6, wherein the catheter comprises a first passage and wherein the retractable needle is oriented coaxially with the first passage and configured to slide out of the first passage of the catheter. 9. The vascular system of claim 8, further comprising a second passage that fluidically couples the first passage to the fluid extraction assembly, wherein the second passage is configured such that fluid can flow from the first passage to the fluid extraction assembly. 10. The vascular access system of claim 1, further comprising an auto-retract feature that is configured to automatically retract the retractable needle. 11. The vascular access system of claim 1, wherein the tube is coupled to a proximal side of the catheter hub. 12. The vascular access system of claim 1, wherein the tube is configured to extend from a proximal side of the catheter hub at an angle relative to a central axis of the catheter hub. 13. The vascular access system of claim 1, wherein the connector is a needleless connector. 14. The vascular access system of claim 1, wherein the retractable needle is configured to extend through the catheter. 15. The vascular access system of claim 1, wherein the connector includes a plurality of threads to mechanically couple the connector to a device. 16. The vascular access system of claim 1, wherein the flow controller is removable. 17. The vascular access system of claim 1, wherein the flow controller is a cap. 18. The vascular access system of claim 1, wherein the flow controller is a seal.
