Abstract
Various embodiments of an elongate surgical device configured to travel along a tortuous body lumen to a surgical site are provided herein. In one embodiment, the device can include a tensioning element extending through a channel formed along a length of the device and the tensioning element can translate an articulation force to the working end of the device. During such articulation of the device, a portion of the channel can be configured to allow the tensioning element to exit the channel and move away from a longitudinal axis of the device thereby optimizing a mechanical advantage relative to the distal end of the device and thus maximizing the force capable of being delivered thereto. Additionally, various embodiments of a method for articulating a working end of an elongate surgical device are provided herein.
