Abstract:
1. An apparatus for effecting at least one anatomical structure of a body, comprising: at least one first arrangement which is structured to be at least partially inserted into the body and including an opening; at least one second arrangement operatively connected to the first arrangement; at least one third arrangement which is coupled to the at least one second arrangement, the at least one third arrangement movable to at least one of increase or decrease a size of the opening by a motion thereof in a first direction; and a tension-setting arrangement coupling the second and third arrangements to one another to effect movement; the second arrangement movable parallel to the first direction, wherein, during use of the apparatus to treat tissue when the at least one anatomical structure is provided in the opening and is pressed on by movement of the at least one third arrangement to decrease the size of the opening, a first motion of the at least one third arrangement toward the at least one anatomical structure in the first direction is at least one of reduced or terminated while a second subsequent motion of the at least one second arrangement at least one of (i) remains at least the same, or (ii) is reduced to a lesser extent than that of the first motion, the second arrangement remaining coupled to the third arrangement during the subsequent second motion, and the tension-setting arrangement maintaining the coupling of the second and third arrangements during the subsequent second motion.
