1. A programmable personal device (10), in particular an implantable medical device such as a cardiac pacemaker, cardioverter, defibrillator or the like, including:

  • a. a first data communication interface (11) for a wireless data transmission, wherein the personal device is able to receive data containing programming instructions via the first data communication interface,b. a second data communication interface (13) for a wireless data transmission, wherein the personal device is also able to receive data containing programming instructions via the second data communication interface (13), and wherein the second data communication interface (13) differs from the first data communication interface (11) with regard to one or more of;

    (1) the data format required for the data transfer, and(2) the data transfer technique for the data transfer,c. a memory (17),d. a programmable controller (15) connected to the memory (17), wherein the programmable controller (15);

    (1) is at least indirectly connected to the first and second data communication interfaces (11, 13)(2) controls functions of the personal device on the basis of control parameters,(3) stores, in combination with the memory (17);

    (a) at least one instantaneous control parameter value, and(b) one categorical characterization for each control parameter, wherein the categorical characterization indicates;

    i. that a particular control parameter belongs to one of at least a first category and a second category, andii. how the programmable controller (15) performs after receipt of a programming instruction via the second data communication interface (13),(4) has functionality defined such that after execution of a programming instruction which contains only control parameter values for control parameters of;

    (a) a first category, these control parameters are stored permanently as instantaneous control parameter values in the memory (17), so that the function of the programmable controller is determined by these control parameter values until receipt of another programming instruction;

    (b) a second category, these control parameter values are stored for a predetermined limited period of time as instantaneous control parameter values in the memory (17), so that the function of the programmable controller (15) is determined by these control parameters until the end of the predetermined period of time and then again by the control parameter values set previously.
