Patent ID: 8100884

Claim:
An adapter for connecting a catheter assembly to a trocar comprising: a generally tubular body having: a first end adapted to engage a connecting end of a trocar; and an open second end adapted receive thereinto an end of an at least one catheter lumen and to releasably engage outer surface portions thereof; and a longitudinal axis extending between the first end and the second end; and a movable locking member movable along the longitudinal axis for urging the second end into engagement with the end of the at least one catheter lumen after insertion into the open second end and thereby releasably connecting the adapter to the at least one catheter lumen, the movable locking member having a minimal transverse dimension and substantially smooth continuous outer surface therealong, wherein the open second end includes lumen-engaging inner surface portions adapted to frictionally engage adjacent outer surface portions of the at least one catheter lumen upon being urged thereagainst by the movable locking member and thereby releasably connecting the adapter to the at least one catheter lumen in a frictional fit therewith sufficient to enable pulling thereof through a subcutaneous tunnel defined by the trocar.
