DEVICES AND METHODS FOR FLUID TRANSFER THROUGH A PLACED PERIPHERAL INTRAVENOUS CATHETER

Abstract 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 having an outer surface forming a plurality of ribs, and defining an inner volume and a slot in communication with the inner volume, the inner volume configured to receive the catheter, a 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 actuator operatively coupled to the introducer, the first portion of the actuator disposed outside of the inner volume, the first portion including a surface in contact with the outer surface of 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 in contact with at least one rib from the plurality of ribs, 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, the first portion of the actuator configured to move along at least a portion of the ribs from the plurality of ribs as the actuator moves the catheter between the first position and the second position, the surface of the actuator and the plurality of ribs providing a haptic output associated with a position of the catheter.
