Abstract

A tissue-sampling device according to one disclosed embodiment includes a cannula and a stylet formed with at least first and second longitudinally spaced tissue-receiving notches and being slidably received in the cannula. The stylet and cannula are longitudinally movable with respect to each other. A trigger-mechanism is operatively coupled to at least the cannula. The trigger-mechanism is configured such that, whenever the stylet is in an extended position and the cannula is in a retracted position, activating the trigger-mechanism causes the cannula to move over the first tissue-receiving notch, but not the second tissue-receiving notch, and activating the trigger-mechanism another time causes the cannula to move over the second tissue-receiving notch.
