    摘要： An implantable sensing device includes a sensing element and a mounting element. The mounting element has a first end and a second end with a longitudinal axis therethrough. The sensing element is positioned at the first end of the mounting element with the mounting element having a length that is adjustable along the longitudinal axis. The mounting element includes a sleeve having a first open end and a second open end with the longitudinal axis therethrough. The sensing element is positioned in the second open end and includes a lead body connected thereto extending through the second open end. The sleeve includes an outer sleeve member coupled for adjustment along the longitudinal axis with respect to an inner sleeve member. Further, the mounting element may include a flexible element about the first open end extending outwardly relative to the longitudinal axis and a flange element extending outwardly relative to the longitudinal axis from at least a portion of the second end. The device can be implanted in a bone with the flange element and the flexible element for direct or indirect contact with the anterior and posterior surface of the bone. A method of implanting the sensor includes providing a sensing element and drilling a hole in a bone. The hole extends to the intrathoracic cavity. The sensing element is inserted into the hole and positioned in communication with a region in the intrathoracic cavity. The hole is drilled in the manubrium. When the flexible element is inserted into the hole, the flexible element about the first open end collapses towards the longitudinal axis and when the sensor mounting assembly is removed from the hole, the flexible element collapses towards the longitudinal axis during removal. Methods for providing stimulation of a patient to treat respiratory disorders using the sensor are also provided as are stimulation systems for providing stimulation of a patient to treat respiratory disorders.

    摘要： The implantable eyelid electrode apparatus includes a body of nonconductive material having first and second edges and first and second ends. A longitudinal axis extends between the first and second ends and a distance from the longitudinal axis to at least one of the first and second edges decreases towards at least one of the first and second ends. Conductive material is positioned at a surface of the body and at least one lead wire is in electrical contact with the conductive material. Further, the conductive material may include a number of conductive electrodes which are capable of being connected as an anode, a cathode, or left in an open configuration. The conductive electrodes may be strip electrodes positioned perpendicular to the longitudinal axis, and further, the plurality of conductive electrodes may be configured in a guarded multipolar configuration. An electrode device may be implanted in the upper eyelid or the lower eyelid or both. Moreover, a method for implanting an electrode apparatus includes positioning the electrode apparatus adjacent the orbicularis oculi muscle fiber such that the conductive material of the implantable eyelid electrode is adjacent the surface of the muscle fibers. The conductive electrodes, which may be of a strip configuration, are positioned with their length perpendicular to the muscle fibers, when implanted, to promote current passing parallel to the muscle fibers.

    摘要： A cardiac assist device having circadian muscle stimulation. In particular the present invention operates in one of two states, either day mode or night mode. During the day mode, muscle stimulation and conditioning are performed according to a first schedule. During the night mode, muscle stimulation and conditioning are performed according to a second schedule. In addition, the night mode is only reached if the night mode is permitted, a set number of sensed beats are less than the night mode rate, and the time of day is nighttime. The night mode is interrupted if the night mode is turned off, the time of day is daytime, or a set number of beats are greater than the night rate. In short, the present invention provides for skeletal muscle stimulation at a less fatiguing level during the night than during the day.

    摘要： A cardiac assist system which provides simultaneous cardiac assistance during a confirmed cardiac arrythmia, but which provides for the inhibition of the cardiac assistance in the event battery voltage drops below a predefined point. In particular the present invention features a battery voltage safety limit during the deliver VF therapy state. During VF therapy state the system provides skeletal muscle stimulation while charging a defibrillation output capacitor. The battery voltage safety limit is set above a threshold which will insure proper device functionality, i.e. above the power-on-reset threshold (hereafter "POR"). If the battery voltage safety limit is reached the system inhibits the skeletal muscle stimulation to thereby avoid reaching the POR threshold, but yet still maintain the charging of the defibrillation output capacitor. Once charging of the defibrillation output capacitor is completed a synchronization routine is begun and defibrillation therapy is delivered. In such a manner the present invention prevents the dual demands of skeletal muscle stimulation along with charging of the defibrillation output capacitor to cause the battery voltage to collapse and drop below the power-on-reset threshold.
