A mechanical dilatation and medicament delivery device for enlarging a flow passage of a vessel by dilating and delivering a liposome or micelle-encapsulated therapeutic agent or medicament to an obstruction in the vessel. Preferably, a marker substance is introduced into the air before applied to the objects, and the collected heated air is analyzed also for the presence of the marker substance. A detection device detects the first physical value representing the data and a second detection device is provided for detecting a second physical value of the storage cells or constituents of the same, especially of the storage element, especially the leakage current of the storage capacitor provided for storing the data. The transformer circuit includes a transformer and a capacitor.
