    Abstract: A tissue clipping device and system, and method for clipping tissue are disclosed. The tissue clipping device includes a clip with clip arms that is slidably disposed within a channel of a lock tube. The clip is designed to move between an open configuration in which distal ends of the clip arms are separated from each other for receiving tissue therebetween, and a closed configuration in which the distal ends of the clip arms are closer to each other than in the open configuration for clipping the tissue received therebetween. The tissue clipping system further includes a delivery device for delivering and deploying the tissue clipping device. The delivery device is releasably coupled to the tissue clipping device.
