ABSTRACT:
A closing system is described and a correspondingly suitable method for the selective opening and closing of a tubular body organ, comprising a closing element and a regulating system controlling the closing element. Furthermore described are a method and a system for the electronic control of an artificial fine-sensory sphincter implant, with at least one sensor signal or, respectively, sensor value acting—in the method or, respectively, in the system—analog to the difference between the internal bladder pressure and the cuff pressure, and being converted in an analog or digital electronic circuit by means of calculator and comparator functions or, respectively, calculator and comparator elements and being compared with reference values such that an actuator system will be controlled such that the cuff pressure or, respectively, the differential pressure between cuff and urinary bladder moves either in a low area limited by two threshold values or above a specific safety pressure or below that in case of miction.
