Abstract:
1. An automated control device for deforming a patient's tissue during a procedure, comprising: a tissue engager adapted to engage a patient's tissue; a sensor configured to produce a first signal based on the deformation of the patient's tissue; and an automated control system configured to control the tissue engager to deform the patient's tissue based on the first signal received from the sensor; wherein the automated control system: calculates a variance in the plurality of measurements over an interval of time preceding an instantaneous measurement of the first signal, wherein the variance is a statistical distribution of amplitude of the plurality of measurements during the interval of time preceding the instantaneous measurement of the first signal; compares the substantially instantaneous measurement of the first signal to the calculated variance in the plurality of measurements over the interval of time preceding the instantaneous measurement; controls a motion of the tissue engager based on the detected state of the patient's tissue based on the comparison.
