1. An apparatus, comprising:
- a catheter having a proximal end portion and a distal end portion and defining a lumen extending through the proximal end portion and the distal end portion;
an introducer having a proximal end portion and a distal end portion and defining a lumen extending through the proximal end portion of the introducer and the distal end portion of the introducer, the lumen of the introducer configured to receive the catheter, the distal end portion of the introducer configured to be coupled to an indwelling peripheral intravenous line; and
an actuator coupled to the introducer, a portion of the actuator being movably disposed within the introducer and coupled to the proximal end portion of the catheter, the actuator configured to move relative to the introducer to move the catheter between a first position and a second position, the catheter disposed within the introducer when in the first position, the distal end portion of the catheter disposed beyond the distal end portion of the introducer such that at least a portion of the catheter is disposed within the indwelling peripheral intravenous line when the catheter is in the second position and the introducer is coupled to the indwelling peripheral intravenous line, the introducer having a fixed length as the actuator moves the catheter between the first position and the second position.

Abstract
An apparatus for performing phlebotomy through a peripheral intravenous line. The apparatus includes an introducer and a catheter configured to advance the catheter through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the catheter and place in fluid communication with the peripheral intravenous line. When advanced the catheter is configured to transport a bodily fluid (i.e. blood) to a volume outside of the body.

11. An apparatus, comprising:
-
a catheter having a proximal end portion and a distal end portion and defining a lumen extending through the proximal end portion and the distal end portion; an introducer having a proximal end portion and a distal end portion, the introducer defining a lumen extending through the proximal end portion of the introducer and the distal end portion of the introducer and configured to receive the catheter, the distal end portion of the introducer configured to be coupled to an indwelling peripheral intravenous line, the introducer defining a slot along a predetermined length of the introducer; and an actuator coupled to the catheter, a portion of the actuator disposed within the slot defined by the introducer and movable within the slot along the predetermined length of the introducer from a first position to a second position, the catheter being disposed within the introducer when the actuator is in the first position, at least a portion of the catheter being disposed distal to the introducer when the actuator is in the second position such that, when the introducer is coupled to the indwelling peripheral intravenous line, the distal end portion of the catheter extends beyond a distal end portion of the indwelling peripheral intravenous line. - View Dependent Claims (12, 13, 14, 15)

16. An apparatus, comprising:
-
a catheter having a proximal end portion and a distal end portion and defining a lumen extending through the proximal end portion and the distal end portion; an introducer having a proximal end portion and a distal end portion, the introducer defining a lumen extending through the proximal end portion of the introducer and the distal end portion of the introducer and configured to receive the catheter; a locking mechanism coupled to the distal end portion of the introducer and configured to physically and fluidically couple the introducer to an indwelling peripheral intravenous line; and an actuator coupled to the introducer, a portion of the actuator being movably disposed within the introducer and coupled to the proximal end portion of the catheter, the actuator configured to move relative to the introducer to move the catheter between a first position and a second position, the locking mechanism configured to fluidically isolate the catheter within the introducer when the catheter is in the first position, the locking mechanism configured to receive a portion of the catheter as the catheter is moved toward the second position, the distal end portion of the catheter disposed beyond a distal end of the indwelling peripheral intravenous line when the catheter is in the second position and the locking mechanism is coupled to the indwelling peripheral intravenous line, the introducer having a fixed length as the actuator moves the catheter between the first position and the second position. - View Dependent Claims (17, 18, 19, 20)
