Implantable pulse generator having a pulse generation device

An implantable pulse generator, comprising:

• a pulse generation device configured to generate an output pulse, the pulse generation device comprising a control unit, a shock generation circuitry and an output circuitry,
• wherein the shock generation circuitry comprises at least one first energy storage device, at least one second energy storage device and a first switching device, and
• wherein the control unit is configured to control said shock generation circuitry to generate said output pulse by selectively connecting, using the first switching device, said at least one first energy storage device and said at least one second energy storage device to said output circuitry,
• wherein the first switching device is electrically connected, at a first circuit node, to the at least one first energy storage device and is configured to connect, in a closed state, the at least one first energy storage device with the at least one second energy storage device and to disconnect, in an open state, the at least one first energy storage device from the at least one second energy storage device,
• wherein the shock generation circuitry comprises a first connection line connecting said first circuit node to the output circuitry and a second connection line connecting the at least one second energy storage device to the output circuitry,
• wherein the shock generation circuitry is configured to generate said output pulse by supplying energy to the output circuitry, in the open state of the first switching device, from the at least one first energy storage device via the first connection line and, in the closed state of the first switching device, from the at least one first energy storage device and the at least one second energy storage device via the second connection line,
• wherein, in a closed state of the first switching device, the at least one first energy storage device and the at least one second energy storage device are connected in series, and
• wherein the shock generation circuitry comprises a first diode arranged in the first connection line.
