1. A suturing device comprising:
a cannula including a needle compartment defining a needle passage terminating in a distal opening;
a needle pusher provided in the cannula;
a plunger movable between an extended position and a depressed position;
a spring, wherein movement of the plunger from the extended position toward the depressed position compresses the spring;
a shuttle, wherein the spring exerts a biasing force on the shuttle in an advance direction when the plunger is in the depressed position;
a button operably engaged with the shuttle, wherein the spring biases the shuttle in the advance direction after the button is depressed, which pushes the needle pusher in the advance direction; and
a tether, which is a cable configured to sustain a tensile force, but not a compressive force, connecting the plunger with the shuttle in a manner such the tether pulls the shuttle away from the distal opening when the plunger is moved from the depressed position toward the extended position.
