Abstract

A trocar assembly includes a cannula assembly, an obturator assembly, and a catch arm. The cannula assembly has a housing, a cannula, and a working channel defining a longitudinal axis from a proximal opening to a distal opening. The obturator assembly includes a proximal head, a distal tip, and a shaft extending therebetween. The catch arm is selectively moveable from a retracted position to a first and second deployed positions and is configured to releasably capture a suture thread. In the retracted position, the catch arm is positioned radially inward from the first deployed position. In the first deployed position, the catch arm is positioned radially outward from the retracted position. In addition, the catch arm is configured to be moved a predetermined distance from the first deployed position to the second deployed position and release the captured suture thread therefrom.
