Abstract:
1. A method of acquiring tissue from within a hollow body organ, comprising: positioning a first acquisition member and a second acquisition member coupled to a distal end of an elongate shaft adjacent to a region of tissue within the hollow body organ, the first and second acquisition members each including a tissue adhering cavity; with the first and second acquisition members positioned adjacent the region of tissue, moving the first and second acquisition members from a closed configuration in which the first and second acquisition members are in apposition to one another along a longitudinal axis of the elongate shaft to an open configuration in which the first and second acquisition members remain in apposition to one another along the longitudinal axis, wherein, as the first and second acquisition members are being moved to the open configuration, tissue from the region is being adhered within each of the first and second acquisition members into the tissue adhering cavities of the first and second tissue acquisition members; and moving the first and second acquisition members from the open configuration to the closed configuration, thereby compressing the adhered tissue between the first and second acquisition members in the closed configuration while the tissue remains within the tissue adhering cavities.
