Patent attributes
Systems and methods of in situ unclogging a working channel in a medical device during a procedure are disclosed. An exemplary unclogging system comprises a flow sensor to sense a flow rate through a working channel, and a control module to detect a channel state indicating a presence or absence of clogging based on the flow rate. In the presence of channel clogging, the control module can control one or more of an irrigation source or a suction source to provide respectively irrigation fluid or suction pressure to unclog the obstructed channel. The control module can adjust one or more of an irrigation flow rate or a suction flow rate through the working channel to maintain a desired pressure of the anatomical environment at the anatomical site, or to maintain a desired flow condition in the working channel, during the procedure.
