1. A delivery device for delivering an instrument through an intravenous catheter, comprising:
a housing, comprising a port;
a connector, wherein the connector comprises:
a primary fluid pathway; and
a plurality of secondary fluid pathways in fluid communication with the primary fluid pathway;
a rotary element disposed within the housing and coupled to the connector, wherein the connector extends through the rotary element, wherein the rotary element comprises:
a groove extending around at least a portion of a circumference of the rotary element; and
a channel; and
the instrument, comprising a first end and a second end, wherein the instrument is disposed within the groove and between the rotary element and the housing,
wherein the rotary element is configured to rotate with respect to the housing between a first position and a second position,
wherein in response to the rotary element being in the first position, the second end of the instrument is aligned with the plurality of secondary fluid pathways, the channel is not aligned with the plurality of secondary fluid pathways, and the first end of the instrument is disposed in a first location;
wherein in response to the rotary element being in the second position, the channel is aligned with the plurality of secondary fluid pathways, the second end of the instrument is not aligned with the plurality of secondary fluid pathways, and the first end of the instrument is disposed in a second location.
 
12. A catheter system, comprising:
a catheter assembly, comprising:
a catheter adapter; and
a catheter having a distal end, wherein the catheter extends distally from the catheter adapter; and
a delivery device coupled to the catheter assembly, comprising:
a housing, comprising a port;
a connector, wherein the connector comprises:
a primary fluid pathway; and
a plurality of secondary fluid pathways in fluid communication with the primary fluid pathway;
a rotary element disposed within the housing and coupled to the connector, wherein the connector extends through the rotary element, wherein the rotary element comprises:
a groove extending around at least a portion of a circumference of the rotary element; and
a channel; and
an instrument, comprising a first end and a second end, wherein the instrument is disposed within the groove and between the rotary element and the housing,
wherein the rotary element is configured to rotate with respect to the housing between a first position and a second position,
wherein in response to the rotary element being in the first position, the second end of the instrument is aligned with the plurality of secondary fluid pathways, the channel is not aligned with the plurality of secondary fluid pathways, and the first end of the instrument is disposed in a first location, wherein the first location is distal to the distal end of the catheter,
wherein in response to the rotary element being in the second position, the channel is aligned with the plurality of secondary fluid pathways, the second end of the instrument is not aligned with the plurality of secondary fluid pathways, and the first end of the instrument is disposed in a second location, wherein the second location is proximal to the distal end of the catheter.
 
15. A delivery device for delivering an instrument through an intravenous catheter, comprising:
a housing, comprising a first port, a second port, and a protrusion;
a rotary element disposed within the housing, wherein the rotary element comprises:
a groove extending around at least a portion of a circumference of the rotary element;
an upper end, comprising a connector;
a lower end;
a lumen extending through the upper end and the lower end;
an upper septum disposed within the lumen;
a lower septum disposed within the lumen, wherein in response to connection of a medical device to the connector, the upper septum is configured to move towards the lower septum to allow fluid to flow around the upper septum, and
the instrument, comprising a first end and a second end, wherein the instrument is disposed within the groove and between the rotary element and the housing,
wherein the rotary element is configured to rotate with respect to the housing between a first position and a second position,
wherein in response to the rotary element being rotated to the first position, the lower septum contacts the protrusion and is moved towards an opening, the lower septum divides the lumen into an upper chamber and a lower chamber sealed from the upper chamber, the upper chamber is in fluid communication with the second end of the instrument, the instrument extends through the first port, and the first end of the instrument is disposed in a first location, wherein the second port is in fluid communication with the lower chamber;
wherein in response to the rotary element being rotated to the second position, the lower septum moves away from the opening, the upper chamber, the lower chamber, and the second end of the instrument are in fluid communication, and the first end of the instrument is disposed in a second location.
