摘要： Implantable electrode lead for tissue stimulation adapted to be attached to an implantable tissue stimulator provided with a pulse generator, the electrode lead comprises at least two stimulation electrodes to apply stimulation pulses to said tissue and arranged close to the distal end of the electrode lead, and at least two electrical conductors to connect said electrodes to said pulse generator. The electrode lead further comprises a switching unit arranged close to the distal end of the electrode lead and adapted to switch the electrode lead between a local pacing mode and a normal pacing mode, the switching unit being controlled by a mode control signal. Further, a pacing module is arranged close to the distal end of the electrode lead and in relation to the switching unit and being connectable to said at least two stimulation electrodes, the pacing module includes a pulse generating unit to generate stimulating pulses to be applied to the tissue by said stimulation electrodes. When the electrode lead is in the local pacing mode the electrical conductors are disconnected from said stimulation electrodes which instead are connected to the pacing module, and when the electrode lead is in the normal pacing mode the electrical conductors are connected to the stimulation electrodes.

摘要： The invention relates to a medical implantable lead of the kind being adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ (2) inside the body. The lead (3) comprising a fixation means (6) in a distal end, which is adapted to fixate a distal end of the lead (3) to the organ, an electrode member (6) in the distal end adapted to be in contact with tissue of the organ and receive and/or transmit electrical signals from and/or to the organ, and at least one electrically conducting coil (8, 9), which includes one or more electrically conducting helical wires (11) and which is adapted to connect the electrode member in the distal end with a monitoring and/or controlling device (1) in a proximal end of the lead. The one or more individual wires (11) of the coil comprises a wire core (12) which is provided with a surrounding electrically insulating layer (13), which in its turn is provided with a surrounding electrically conducting shield layer (14), and the coil is close-lapped such that electrically conducting shield layers of adjacent loops of the coil are in electrical contact with each other.
