摘要：
Described here are closure devices and methods for ligating tissue, such as the left atrial appendage, and tensioning devices and mechanism for actuating these devices. The tensioning mechanisms and devices may allow a user to apply one or more predetermined forces to a suture or other portion of the closure devices. The closure devices may comprise a suture loop releasably attached to a snare loop assembly, and a tensioning mechanism or device may be configured to tighten the suture loop and/or release the suture loop from the snare loop assembly.
