The invention relates to a device for treating bladder emptying dysfunctions of a human, in which a catheter that can be inserted into the urethra is provided with a bladder emptying channel and with a balloon arrangement, which serves to seal the bladder and to hold the catheter inside the bladder lumen and which can be filled with a fluid. To ease creation of a profile, a node may be enabled to connect to a third-party social media site where the node already has an established profile. In this manner, pixels provided in positions shifted for each row can be connected with a simple wiring layout. In addition, the controller requests a piece of updated context information from one or more units to be controlled if the simulated context information matches the context information at the given time outside the present limits.
