Abstract: An electrical female connector for affixing a contact pin of an electrode cable in a connector part of a heart stimulator has a sleeve which is elastic and which has a curved shape in a relaxed condition. The sleeve is straightened to a substantially straight configuration when the contact pin is inserted into the sleeve, and thereupon rebounds back to a partially curved configuration so as to clamp the contact pin inside the sleeve.

Abstract: An evoked response detector for a heart stimulator determines evoked response in the presence of polarization. The heart stimulator has a pulse generator which produces stimulation pulses of varying amplitudes, and a lead adapted for introduction into the heart of a patient is connected to the pulse generator for delivering stimulation pulses to the heart. The evoked response detector includes measuring and memory circuitry for measuring and storing the electrode signals picked up by the lead in response to the delivered stimulation pulses, at least one of these stimulation pulses having a sufficiently high amplitude for obtaining capture. Each measured electrode signal contains two signal components, one of these signal components being proportional to the amplitude of the associated stimulation pulse and the other signal component being substantially constant, independent of the associated stimulation pulse amplitude. An analyzing unit determines the evoked response signal from a predetermined relation between the amplitudes of at least two stimulation pulses of different amplitudes and the resulting measured electrode signals.

Abstract: An electrode device which has a proximal end and distal end, contains of a number of thin, insulated electrical conductors each with a proximal end and a distal end, the conductors being equipped with implantable electrode contacts means which are electrically connected to the conductors. These contacts are designed to be brought into electrical contact with tissue in one or more cavities in a human body. Each conductor in the cable device is supported by a pre-shaped stiffening element which runs along and is connected to the conductor, made of an elastic polymer material, resorbable in vivo, which is biodegradable and biocompatible. The stiffening element imparts an arched shaped to the conductor, at least in the area in which its contact is located, to cause the contact to press against the adjacent cavity wall. The cable device also includes a longitudinal channel in which a stylet can be inserted for temporary, linear stretching of the cable device and the arched sections of its conductors.

Abstract: An implantable defibrillator has an electrode lead system a sensing unit for sensing the condition of the heart and emitting a condition signal corresponding to that condition, a control unit for determining the heart's condition from the condition signal and, if a state of fibrillation is present, sending a command signal to a shock pulse generator, which, depending on the command signal, delivers at least one defibrillation shock to the heart via the electrode lead system. The shock being formal of one or more low-energy pulses with an energy less than 2 Joules and a very high voltage, i.e. more than 1,000 Volts. Each low-energy pulse thus has a voltage greatly exceeding the voltage in a conventional defibrillation shock and less energy than the energy in a conventional defibrillation shock.
