    摘要: An implantable cardiac monitor is arranged for detecting both arrhythmias and ischemia of the human heart. The monitor includes subcutaneous electrodes for establishing electrical contact with the heart and a sense amplifier coupled to each electrode for generating an electrocardiogram of a heart beat sensed at each of the electrodes. The electrocardiograms are digitized and the digital samples thereof are stored in a memory. A microprocessor processes the digital samples of the electrocardiograms and generates characterizing data indicative of the physiology of the heart. The cardiac monitor includes telemetry to permit the cardiac data to be interrogated externally of the patient for obtaining the generated cardiac data indicative of arrhythmic and ischemic episodes.

    摘要: An implantable atrial defibrillator provides cardioverting electrical energy to the atria of a human heart in need of cardioversion. The atrial defibrillator includes a first detector for detecting atrial activity of the heart and an atrial fibrillation detector responsive to the first detector for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a pacing output circuit responsive to the atrial fibrillation detector for pacing the ventricles of the heart at a pacing rate when the atria of the heart are in need of cardioversion and a cardioverter stage for applying the cardioverting electrical energy to the atria of the heart after the pacing output circuit has paced the ventricles for a predetermined number of cardiac cycles. The pacing output circuit stabilizes the cardiac rate of the heart prior to the application of the cardioverting electrical energy.

    摘要: A porous electrode for pacemakers is comprised of a plurality of platinum globules sintered together to form a porous mass of semi-hemispherical shape at the end of a platinum electrode stem. The globules, which are themselves made by sintering together spherically-shaped particles of approximately one micron diameter, provide the globules with an irregular outer surface of high total surface area. The globules have diameters within a critical range of 40-200 microns. The large total surface area of the globules improves the sensing function of an electrode configuration of given size and surface area, while the globule diameters of 40-200 microns have been found to beneficially accommodate tissue ingrowth within the electrode. In a preferred method of making the electrode, the platinum globules, which are formed by sintering together platinum particles of much smaller size, are mixed with organic solvent and organic binder to form a paste. After application of the paste to the base of an electrode stem and pressing of the paste using a mold so as to form the paste into the desired semi-hemispherical shape, the electrode is heated to evaporate the organic solvent, and the electrode is then placed in a sintering furnace to sinter together the platinum globules and form the completed electrode.

    摘要: A suture sleeve for securing the leads of a multiple lead implantable medical device includes lead gripping and anchoring portions. The sleeve has a pair of flexible side walls and longitudinally extending channels for receiving the leads. The side walls of at least the gripping portion have longitudinally extending, confronting, spaced apart edges and comprises two layers one of which is formed of a soft plastic such as silicone and the other of which is formed of a harder but flexible material such as polysulfone. Sutures placed and tied about the gripping portion compress the sleeve about the leads. Tightening of the sutures brings the confronting edges of the gripping portion of the sleeve into engagement thereby precluding further compression of the sleeve and preventing damage to the leads.

    摘要: A bipolar electrode assembly for attachment to heart tissue for use with a pacemaker. The assembly has a hub member with a helical screw-in coil that acts as a first electrode and is used to attach the assembly to the heart tissue. The assembly further comprises a plurality of appendages that extend from the hub member and each have an electrode segment of electrically conductive material. The electrode segment of the appendages can act together as a single second electrode, or alternatively as a separate, independent electrodes, which may selectively be used for pacing or sensing. The electrode segments not only act as electrodes, but also allows heart tissue to grow directly into the conductive material to help secure the assembly to the heart. The assembly also has apertures and grooves for suture connection of the assembly to the heart. Methods of manufacturing the assembly and connecting the assembly to a heart are also described.

    摘要: A suture sleeve for anchoring the lead body of an implantable medical device, such as a cardiac pacemaker, includes an elongated tubular member having a lumen for receiving the lead body. The tubular member has external threads for receiving a threaded collar. The tubular member and collar have engaging, tapered surfaces whereby tightening of the collar on the tubular member compresses a portion of the tubular member into gripping engagement with the lead body. The tubular member and collar have surfaces which come into contact upon tightening of the collar so as to limit compression of the lead body and thereby prevent damage thereto.

    摘要: An implantable atrial defibrillator provides a pulse of defibrillating electrical energy to the atria of the heart in synchronism with sensed R waves in response to non-coincident sensing of an R wave at first and second areas of the heart. The defibrillating pulse is provided after a predetermined number of consecutive R waves are non-coincidently sensed to assure reliable synchronization. The atrial defibrillator is also operational in a marker mode wherein a number of synchronization marker pulses are delivered to the heart for detection on an externally generated electrocardiogram. The atrial fibrillation detector of the defibrillator is normally disabled and is activated when the sensed ventricular activity indicates a probability of atrial fibrillation to conserve a depletable power source. A plurality of lead systems are also described for use with the atrial defibrillator which reduce the quantity of electrical energy required to defibrillate the heart and ensure that the delivered atrial defibrillating electrical energy is substantially confined to the atria of the heart.
