Abstract

Closure devices and methods for ligating tissue, such as the left atrial appendage, generally, include an elongate body having a first lumen therethrough, a snare loop assembly, a vacuum tube, and an imaging device. The snare loop assembly may include a snare and a suture loop releasably coupled to the snare and may at least partially extend from a distal end of the elongate body. The vacuum tube may be slidably positioned within the first lumen to extend through the snare loop assembly. The imaging device may be disposed within the lumen of the vacuum tube.
