Abstract: 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 inside the body, comprising in a distal end a combined fixation means and electrode member in form of a helix (4), which is rotatable in relation to the lead and extendable out from the distal end by rotation of a tubular torque transferring member (9). The helix is electrically connected to a connector (7) in the proximal end by means of at least one electrically conducting wire (14), which is formed as an electrically conducting coil (11, 17), which is separate from the tubular torque transferring member (19) and which comprises one or more individual wires each comprising an electrically conducting wire core (15) and a surrounding electrically insulating layer (16). The tubular torque transferring member has no electrically conducting function to or from the helix (4), wherein the lead is arranged such that the electrical connection between the helix and the conducting wire is always maintained irrespective of the rotational position of the helix while no electrical connection is present between the helix and the tubular torque transferring member although the helix is rotatable by means of the tubular torque transferring member.

Abstract: Heart stimulating device comprising a stimulation pulse generator arranged in a stimulator housing (2), where the heart stimulating device being connectable to a plurality of stimulation and sensing electrodes (5, 6, 7, 8, 9, 10, 11, 12) arranged at one or many leads (3, 4, 13), the electrodes being adapted to be arranged in connection with the heart to stimulate the heart. The device further comprises a sensing unit adapted to sense electrical heart tissue responses to applied electrical stimulation pulses via said electrodes. The pulse generator is adapted to generate stimulation pulses to be applied to the heart tissue by different electrodes, and for each of the applied pulses resulting in a depolarization wave in the heart tissue a depolarization wave velocity, or a depolarization wave velocity measure, of the wave is determined by the sensing unit and stored in a memory unit. The stored wave velocities, or velocity measures, related to different stimulating electrodes, are compared to each other in a comparison unit and the comparison is used to adapt a stimulation mode when stimulating the heart to optimize the hemodynamic performance of the heart.
