Devices and Methods for Fluid Transfer Through a Placed Peripheral Intravenous Catheter

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 configured to receive the catheter, the introducer defining an inner volume configured to receive the catheter and a slot in communication with the inner volume, the introducer having a proximal end portion, a distal end portion, and an outer surface, with the distal end portion of the introducer configured to be coupled to an indwelling peripheral intravenous line;
• and
• an actuator having a first portion and a second portion, the first portion of the actuator disposed outside of the inner volume and including a surface in contact with the outer surface of the introducer so as to be operatively coupled to the introducer, the second portion of the actuator extending through the slot and disposed within the inner volume, the second portion of the actuator being coupled to the catheter and extending through the slot defined by the introducer such that the first portion of the actuator is connected to the second portion of the actuator, with the actuator configured to be moved relative to the introducer to move the catheter between a first position in which the catheter is disposed in the introducer and a second position in which the distal end portion of the catheter is disposed beyond at least a portion of the indwelling peripheral intravenous line when the introducer is coupled to the indwelling peripheral intravenous line;
• and
• a secondary catheter comprising a distal end and a proximal end, the distal end of the secondary catheter positioned within the inner volume of the introducer and the proximal end of the secondary catheter positioned outside of the introducer, with the secondary catheter extending through an opening in the proximal end portion of the introducer;
• wherein the distal end of the secondary catheter is coupled to the second portion of the actuator, such that movement of the actuator relative to the introducer causes a corresponding movement of the secondary catheter.
