摘要： An active medical implant has a hermetically sealable capsule formed by a first part and a second capsule-closing part, whereby the capsule is arranged to hold a battery unit and an electronics unit, conductors for electrically connecting the battery to the electronics unit and contacts with associated conductors arranged on the exterior of the capsule for connection to electrodes. The first part and the second part are made of an essentially biocompatible material, and a partition wall is arranged to form a first essentially closed space in the first part for the battery unit, and an electrically insulating layer, impermeable to battery chemicals, is arranged on the surfaces of the biocompatible material facing the first closed space. An additional space is formed for the electronics between the capsule-closing part and the partition wall.

摘要： An implantable cardiac stimulator has locking device for a pin-like conductor element of an electrode lead, the locking device having a helical coil which can assume a first, locking position, in which it grips the pin-like conductor element inserted into the coil to prevent longitudinal movement of pin-like conductor element, and a second, release position in which the pin-like conductor element is free to move in and out of the coil in relation to the coil's longitudinal axis. The first position is assumed when the coil is not influenced in its helix diameter increasing direction and the second position being assumed when the coil is influenced in its helix diameter increasing direction. The locking device also has a blocking component which only prevents the coil from rotating in the unwinding direction around its longitudinal axis in the locking device.

摘要： A common feedthrough for an implantable apparatus for stimulating living tissue, such as a pacemaker, which permits both unipolar and bipolar operation of the pacemaker, is established by a sleeve filled with insulating compound, through which first, second and third conductors proceed. The second conductor and the third conductor are electrically linked to each other at one end, and the third conductor is connected to the sleeve via a joining element. The first conductor is connected to a stimulating pole of the apparatus and to an output terminal at which stimulating pulses are supplied. The free end of the second conductor is connected to an indifferent pole of the apparatus, and the free end of the third conductor is connected to a reference pole of the apparatus. With the conductors connected in this manner, the apparatus can be operated in a unipolar mode. If operation in a bipolar mode is desired, the third conductor is cut outside of the housing.

摘要： A medical implantable lead is adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ inside the body, and has in a distal end, a combined fixation means and electrode member in form of a helix, which is rotatable in relation to the lead and extendable out from the distal end by rotation of a tubular torque transferring member. The helix is electrically connected to a connector in the proximal end by at least one electrically conducting wire, which is formed as an electrically conducting coil, which is separate from the tubular torque transferring member and that includes one or more individual wires each having an electrically conducting wire core and a surrounding electrically insulating layer. The tubular torque transferring member has no electrically conducting function to or from the helix. The lead is arranged such that the electrical connection between the helix and the conducting wire is always maintained regardless 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 the tubular torque transferring member.

摘要： An implantable lead for delivering electrical stimuli to a human heart has a stimulating electrode for transmitting electrical stimuli to the myocardium after implantation, and a mapping electrode for use during implantation. The mapping electrode is configured to deliver electrical stimuli to the heart and to sense intrinsic cardiac activity, for the purpose of finding a suitable fixation position in the myocardium. During the implantation procedure, the mapping electrode is electrically connected to the conductor. The lead is configured to electrically disconnect the mapping electrode from the conductor after a suitable fixation position has been determined.

摘要： A heart monitoring device has a control circuit that derives an impedance value indicative of the impedance between different electrode surfaces. The control circuit determines and monitors a negative rate of change of the impedance value and determines whether the negative rate of change, or its absolute value, increases or decreases over a number of heart cycles. Alternatively or additionally, the control circuit may determine and monitor a relationship between a positive rate of change and a negative rate of change of the impedance value. The device can, in particular, be used to detect and treat a diastolic dysfunction of a heart.
