Abstract
An apparatus includes a catheter, an introducer, and an actuator. A distal end portion of the introducer is configured to be coupled to a peripheral intravenous line. The introducer defines an inner volume having a first portion that defines an axis parallel to and offset from an axis defined by a second portion. A first portion of the actuator is movably disposed in the first portion of the inner volume. A second portion of the actuator is movably disposed in the second portion of the inner volume and coupled to the catheter movably disposed in the second portion of the inner volume. The actuator moves the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which at least a portion of the catheter is disposed within the peripheral intravenous line.
