摘要： A therapy or monitoring system may implement one or more techniques to mitigate interference between operation of a charging device that charges a first implantable medical device (IMD) implanted in a patient and a second IMD implanted in the patient. In some examples, the techniques may include modifying an operating parameter of the charging device in response to receiving an indication that a second IMD is implanted in the patient. The techniques also may include modifying an operating parameter of the second IMD in response to detecting the presence or operation of the charging device.

摘要： A pacemaker provided with a mode switching feature adapted to stabilize ventricular heart rate during atrial fibrillation. In a preferred embodiment of the invention, the device nominally operates in an atrial synchronized pacing mode such as DDD, DDDR, VDD or VDDR. In response to detection of atrial rhythm characteristics consistent with atrial fibrillation, the device switches into a non-atrial synchronized, ventricular rate stabilization pacing mode with the base ventricular pacing rate modulated on a beat by beat basis based upon preceding intrinsic or paced ventricular heartbeat intervals to adjust the pacing interval towards a desired preset rate stabilization target pacing interval which is typically less than the programmed base pacing interval of the device. While the ventricular rate stabilization mode is in effect, the current pacing interval is set equal to the preceding intrinsic or paced interval, with an increment if the preceding interval is less than the desired or target pacing interval, as typically will be the case, or with a decrement if the preceding interval is greater than the desired pacing interval. In a preferred embodiment of the invention, the device paces both the atria and ventricles in a DDI rate stabilization pacing mode with the ventricular pacing interval being modulated.
摘要翻译：心脏起搏器配有模式切换功能，适用于在心房颤动期间稳定心室心率。在本发明的优选实施例中，该装置名义上以心房同步起搏模式（例如DDD，DDDR，VDD或VDDR）操作。为了响应与心房颤动一致的心房节律特征的检测，该装置转换成非心房同步的心室速率稳定起搏模式，其基本心室起搏速度基于先前的固有或起搏心室心跳间隔以搏动为基础进行调整以将起搏间隔调整到期望的预设速率稳定化目标起搏间隔，其通常小于设备的编程的基本起搏间隔。当心室速率稳定模式有效时，将当前起搏间隔设置为等于前一个固有或起搏间隔，如果前一个间隔小于期望的或目标起搏间隔，则增量，如通常情况，或如果前一个间隔大于所需的起搏间隔，则递减。在本发明的优选实施例中，该装置以调节心室起搏间隔的DDI速率稳定起搏模式对心房和心室起搏。

摘要： A system for measuring facial impedance of patients with hemiparesis, or unilateral facial palsy, provides a program for therapeutic stimulus of paralyzed facial muscles. Facial current is generated between an upper electrode (30) above the eyes and a lower electrode (31) on the chin, the facial current in sinusoidal or pulsed form being sub-threshold so as to avoid any muscle stimulus. Impedance measurements are taken by determining the voltage between symmetrically placed facial electrodes (32, 33), or between electrode pairs consisting of one electrode (35, 36) positioned around the eye, cheek or mouth, and a reference electrode (R) placed on the patient's chin so as to provide an effective bottom point of the Wheatstone bridge formed by the face. The impedance measurements are indicative of muscle paralysis, and provide a simple but reliable method of obtaining data useful for facial movement assessment.

摘要： A prosthetic heart valve, either of the mechanical type, or the bioprosthetic type, comprises a circular frame element, a check valve element and a suturing member surrounding the circular frame element. The circular frame element defines a circular opening for the passage of blood therethrough. The check valve element is connected to, and extends across, the circular frame element and is configured to substantially permit the flow of blood through the circular opening in a first direction and to substantially impair the flow of blood through the circular opening in a second direction opposite the first direction. The suturing member surrounds the circular frame element and has a first radial width in a first circumferential region substantially greater than a second radial width in a second circumferential region to define an extended portion of the suturing member. The extended portion of the suturing member can be attached to a downwardly sagging portion of a patient's valve annulus with sutures, thereby ensuring proper orientation of the valve in the patient's heart.

摘要： A system for providing medical electrical stimulation, the system features a pulse generator, the pulse generator generating electrical stimulation pulses of a first amplitude and a second amplitude, first and second elongated leads coupled to the pulse generator, a zener diode which directs electrical stimulation pulses of a first amplitude to the first lead and directs electrical stimulation pulses of a second amplitude to the first lead and the second lead, the means for directing electrical stimulation pulses coupled to the pulse generator. In the preferred embodiment the diodes is electrically coupled to one of the leads such that electrical stimulation of a first amplitude is not passed through the diode while electrical stimulation of a second amplitude is passed through the diode.

摘要： An improved coating and spacer material for a medical device having a blood or tissue-contacting surface comprising a polyalkyleneimine layer which is cross-linked with a cross-linking agent which is at least difunctional in polymerizable vinyl groups which have adjacent strong electron-withdrawing groups and a biomolecule covalently bonded to the cross-linked polyalkyleneimine layer. For example, polyethyleneimine cross-linked with divinyl sulfone could be used. The resulting cross-linked spacer layer has improved uniformity and stability without materially limiting the covalent attachment of a biomolecule such as heparin.
