CLIP DEVICES AND SYSTEMS AND METHODS FOR DEPLOYMENT

摘要

The present embodiments provide clip devices, along with systems and methods for delivering and deploying the clip devices. An exemplary clip device (20) comprises inner (30) and outer (50) segments, and further has a delivery configuration, a tissue receiving configuration and a deployed configuration. A distal region (60) of the outer segment is movable with respect to a distal region (40) of the inner segment, thereby creating a spacing between the inner and outer segments for surrounding tissue in the tissue receiving configuration. The inner and outer segments may be biased to return to the deployed configuration, and may comprise generally identical shapes in the deployed configuration wherein the outer segment is proportionally larger than the inner segment. In one embodiment, the inner and outer segments each comprise "V" shapes in the unbiased state. Various delivery systems and methods are provided for delivering and deploying the clip devices disclosed.
