Abstract
An endoscopic surgical device is provided and includes an endoscopic anchor retaining/advancing assembly including a proximal tube portion and a distal tube portion pivotably connected to one another at an articulation joint; a proximal inner shaft rotatably disposed within the proximal tube portion; a distal inner shaft rotatably disposed within the distal tube portion; and a relatively flexible intermediate drive cable mechanically interconnecting the proximal inner shaft and the distal inner shaft, wherein the intermediate drive cable extends across the articulation joint, wherein the intermediate drive cable defines a central longitudinal axis that is off-set a radial distance from a central longitudinal axis of the proximal tube portion and the distal tube portion.
