TISSUE ACQUISITION DEVICE AND METHOD

摘要

A device and method for acquiring tissue from remote regions of a hollow internal organ, such as the stomach, in preparation for tissue fastening, is disclosed. The device includes (a) an acquisition head defining first and second side-by-side tissue-acquisition chambers, (b) a vacuum channel communicating with each of said chambers, through which a vacuum may be independently applied to the first and second chambers, and a retention element for retaining tissue captured in a chamber. The device allows tissue regions, e.g., folds, to be independently captured and placed in a side-by-side configuration for stapling.
