Systems and methods for phlebotomy through a peripheral IV catheter
First Claim
1. An apparatus, comprising:
- a catheter having a proximal end portion and a distal end portion, the catheter defining a lumen extending through the proximal end portion and the distal end portion of the catheter;
an introducer having a first member and a second member, at least a portion of the second member movably disposed in the first member between a proximal position and a distal position relative to the first member, the second member including a guide, a distal end portion of the guide being disposed in a distal position relative to the first member when the second member is in the distal position;
a locking mechanism coupled to a distal end of the first member, the locking mechanism configured to couple the introducer to a peripheral intravenous line; and
an actuator coupled to the catheter, at least a portion of the actuator disposed in the second member and configured to move from a first configuration toward a second configuration to move the second member from its proximal position to its distal position, the actuator configured to move relative to the second member to be placed in the second configuration when the second member is placed in its distal position, the catheter being disposed within the introducer when the actuator is in the first configuration and disposed within and extending past an end of the peripheral intravenous line when the actuator is in the second configuration.

Abstract
An apparatus includes a catheter, an introducer having a first member and a second member, a locking mechanism coupled to a distal end of the first member and configured to couple the introducer to a peripheral intravenous line, and an actuator coupled to the catheter. The actuator is configured to move from a first configuration, in which the catheter is disposed within the introducer, toward a second configuration to move the second member to a distal position relative to the first member. A portion of a guide of the second member being distal to the first member when the second member is in the distal position. The actuator is configured to move relative to the second member to be placed in the second configuration when the second member is in its distal position such that the catheter is disposed within and extending past an end of the peripheral intravenous line.

10. An apparatus, comprising:
-
a catheter having a proximal end portion and a distal end portion, the catheter defining a lumen extending through the proximal end portion and the distal end portion of the catheter; a first introducer having a proximal end portion and a distal end portion, the distal end portion of the first introducer configured to be coupled to a peripheral intravenous line, the first introducer having an inner surface that defines a channel; a second introducer having a proximal end portion and a distal end portion, the distal end portion of the second introducer including a guide member, at least a portion of the second introducer movably disposed in the first introducer such that a protrusion extending from an outer surface of the second introducer is disposed in the channel, the second introducer having a range of motion relative to the first introducer defined at least in part by the channel; and an actuator coupled to the catheter and at least partially disposed in the second introducer, the actuator configured to move the second introducer through at least a portion of the range of motion to advance a distal end portion of the guide member through at least a portion of the peripheral intravenous line, the actuator configured to move from a first position relative to the second introducer, in which the catheter is disposed in the guide member, to a second position relative to the second introducer, in which the distal end portion of the catheter extends beyond a distal end of the guide member. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method, comprising:
-
coupling a fluid transfer device to a peripheral intravenous line, the fluid transfer device including an introducer having a first member, a second member movably disposed in the first member and including a guide member, an actuator movably disposed in the second member, and a catheter coupled to the actuator; exerting a first force on the actuator, the first force being sufficient to move the second member relative to the first member from a first position, in which the guide member is disposed in the first member, to a second position, in which a distal end portion of the guide member is inserted through a port of the peripheral intravenous line; exerting a second force on the actuator, the second force sufficient to move the actuator relative to the second member when the second member is in the second position to advance the catheter from a first position, in which the catheter is disposed in the introducer, to a second position, in which a distal end portion of the catheter extends past an end of the peripheral intravenous line; coupling a fluid reservoir to the fluid transfer device, the fluid reservoir being fluidically coupled to the catheter; and withdrawing a volume of bodily fluid through the lumen of the catheter into the fluid reservoir. - View Dependent Claims (26, 27, 28, 29, 30)
