Implantable device with elongated electrical conductor

摘要

An implantable medical device having at least one elongated electrical function conductor and an electrode pole connected to the at least one elongated function conductor. The at least one elongated function conductor transmits therapeutic signals or diagnostic signals or both. The electrode pole delivers electrical current or field or sense electrical potentials, or both, in surrounding tissue during use. The implantable medical device includes a sensing device connected to a field-generating electrode pole, a potential-sensing electrode pole, and a reference pole. The sensing device detects generated electrical potentials via the potential-sensing electrode pole in relation to the reference pole, and generates an output signal that represents a detected electrical potential. The implantable medical device includes a control device connected to the sensing device to evaluate an output signal generated by the sensing device, and to control the medical device as a function of the potential detected by the sensing device.
