Abstract:
1. A system for treating tissue, comprising: a device comprising: a first member, and a second member arranged to move relative to the first member to treat tissue; a processor configured to automatically control movement of the second member relative to the first member while the first member remains stationary using position control methodology to compute acceleration and deceleration to move the second member to a next incremental point between points of a position profile in specified periods of time and to enable reversal of direction to return to a starting position, the first and second members cooperatively defining an aperture in the device which depending upon the position of the second member relative to the first member is in fluid communication or is out of fluid communication with a tissue environment; and the processor controlling movement of the second member relative to the first member such that there is a hold period at least at some occurrences of the aperture being in fluid communication with the tissue environment, an optimum hold period determined from a function of a suction rate and a length of the second member.
