Abstract
Methods and systems for automated control of the inflation of an inflatable retention member, e.g. a balloon, in a catheter are disclosed. One catheter is preferably a rectal or anal catheter, and the inflation is controlled by a controller. A plurality of predetermined inflation levels are provided, and for each of level, a pumping time threshold and a pressure level threshold are defined. The pressure in the balloon is continuously measured during the inflation. An inflation level is selected form said plurality of inflation levels, and an electric pump is used to inflate the inflatable retention member. Operation of the electric pump is continued until one of the pumping time threshold and pressure level threshold of the selected inflation level has been reached.
