Abstract: An adapter assembly (120) for connecting a catheter assembly (50,52) to a tunneler (110) having a generally tubular body (122) having a first end (124), a second end (126) and a longitudinal axis (128) extending therethrough between the first end and the second end. The first end (124) of the adapter is constructed to engage the proximal end (114) of a trocar (110). The second end (126) of the adapter is constructed to releasably engage at least one catheter lumen (50,52). A slider (140) is disposed about the adapter (120) and is longitudinally slidable along the adapter. When the slider (140) is slid towards the second end (126) of the adapter, the slider engages a plurality of legs (134a-134d) on the adapter and biases the plurality of legs toward each other and the longitudinal axis of the adapter.

Abstract: An adapter assembly for connecting a catheter assembly to a tunneler is disclosed. The adapter assembly has a generally tubular body having a first end, a second end and a longitudinal axis extending therethrough between the first end and the second end. The first end of the adapter is constructed to engage the proximal end of a trocar. The second end of the adapter is constructed to releasably engage at least one catheter lumen. A slider is disposed about the adapter and is longitudinally slidable along the adapter. When the slider is slid towards the second end of the adapter, the slider engages a plurality of legs on the adapter. The slider biases the plurality of legs toward each other and the longitudinal axis of the adapter. A method of subcutaneously tunneling a catheter using the adapter assembly is also described.
