Abstract
A marker delivery device includes a handle, an elongate cannula, a push rod assembly, and a plunger. The handle includes a first bore disposed within a portion of the handle. The elongate cannula extends distally from the handle along a longitudinal axis. The push rod assembly includes a mating feature. The push rod assembly is disposed within the first bore and extends distally through the cannula. The plunger is disposed within the first bore proximally of the push rod assembly and includes an engagement feature. The engagement feature is removably coupled to the mating feature. The engagement feature is configured to de-couple from the mating feature when the plunger translates the push rod assembly distally.
