A needle driver device includes an arc-shaped track and an arc-shaped needle configured to be received in the arc-shaped track. The arc-shaped needle is moveable along a curved path including the arc-shaped track. The needle driver device further includes a rotary drive mechanism and a needle driver link. The needle driver link has a distal end portion configured to removably engage the arc-shaped needle and a proximal end portion coupled to the rotary drive mechanism. The needle driver device also includes a guide member coupled to the needle driver link and defining a pivot location of the needle driver link between the distal end portion and the proximal end portion of the needle driver link. The needle driver link is rotatable about the pivot location, and the guide member is moveable in response to movement of the needle driver link.
