Abstract
An introducer cannula configured for receiving a medical instrument includes a cannula tube having a side wall surrounding a central lumen, a proximal end, and a distal end. An elongate tissue anchor is positioned in the central lumen of the cannula tube. The elongate tissue anchor has a mounting end and an anchoring free end. The elongate tissue anchor is movable in the central lumen such that the anchoring free end is movable between a retracted position and a deployed position. An actuator is coupled to the proximal end of the cannula tube. The actuator is coupled to the mounting end of the elongate tissue anchor. The actuator is operatively configured to selectively position the anchoring free end of the elongate tissue anchor in one of the retracted position and the deployed position.
