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 battery unit has a battery encapsulation formed by first and second encapsulation parts joined by a weld along a weld zone, with a battery contained in the battery encapsulation between the first and second encapsulation parts. Either the battery has a recess exstending along the weld zone, or overlaping edges of the first and second encapsulation parts are bent away from the battery to form a recess. The recess provides a heating insulating space that protects the battery from damage during welding along the weld zone.

摘要： An active medical implant has a hermetically sealable capsule formed by a first part and a second closing part, the capsule being devised to hold a battery unit, an electronics unit, conductors for electrically connecting the battery to the electronics unit, and contacts arranged on the exterior of the capsule for connection to electrodes. The first part is made, at least in part, of a rolled, multi-layer composite sheet or plate, one layer of which is made of a biocompatible material and a second layer of which is made of a diffusion-proof material which is essentially resistant to corrosive chemicals. The two layers are joined by rolling, with the layer made of biocompatible material constituting the outer wall of the capsule. The closing part contains a layer of the biocompatible material serving as the capsule's outer wall and a partition wall made of diffusion-proof material which is essentially resistant to corrosive chemicals, is arranged to form a first essentially closed space for the power source in the first part. A second space for the electronics unit is formed between the wall closing the capsule and the partition wall.

The electrode lead further has 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 the 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： A medically implantable lead configured for insertion into a human or animal body to be attached in the body with its distal end to tissue inside the body, as a rotatable helix at a distal end thereof that can be screwed into the tissue. The helix serves as an attachment of the lead to the tissue as well as a conductor for conducting electrical signals to the tissue through electrically conducting surfaces on the helix. The surfaces of the helix are partly insulated so as to restrict the conducting of signals between the helix and the tissue to desirable regions. The surfaces of the helix facing inwardly, toward an inner bore of the helix, are electrically insulated. In a method for manufacturing such a lead, the wire forming the helix has protrusions in desired areas and the wire including the protrusions is coated with an electrically insulating layer. The protrusions are uncovered from the insulating layer in desired regions.

The feedthrough has a feedthrough housing with a capacitor element therein having first and second capacitor plate configurations, with a first of the capacitor plate configurations being connected to the RF antenna and a second of the capacitor plate configurations being connected to the RF telemetry circuit. The feedthrough functions both as a hermetic seal and as a galvanic isolation for voltage protection of the components of the RF telemetry circuit, and other circuitry in the sealed housing connected thereto.

摘要： A congestive heart failure monitor has an impedance measuring unit that measures the impedance between at least two electrodes implanted in a patient, to use a detected change of the measured impedance as an indication of a change in the left atrium volume. Any analyzing unit analyzes the measured impedance and detects insipient congestive heart failure dependent on a quotient of a maximum value of the measured impedance and a minimum value of the measured impedance during a cardiac cycle.
