摘要： A system and method for communication between an IMD and an external reader includes bringing a portion of a patient's body into contact with a device-body contact surface of an external reader. The reader transmits a first transdermal carrier wave from the contact surface into the patient's body, where the first carrier wave includes a request for communication with the IMD. The transdermal carrier waves are electrical conductive waves, optical waves, or acoustic waves. Upon detection of the first carrier wave, the IMD transmits a second transdermal carrier wave including a request for an access key from the reader and the reader replies by transmitting a third transdermal carrier wave including the access key back to the IMD. If the access key is valid, the IMD transmits information by radio frequency (RF) in an RF communication mode or a fourth transdermal carrier wave including data from the IMD.

摘要： A hospitalization management system including a heart failure analyzer that receives diagnostic data including at least sensor data representative of one or more physiological signals sensed from a hospitalized patient using one or more sensors and assesses risk of rehospitalization for the patient using the diagnostic data. The outcome of the risk assessment is used during and following the patient's hospitalization for reducing the risk of rehospitalization.

摘要： Improved devices, circuits and methods of operation in implantable stimulus systems. An implantable defibrillator may comprise an H-bridge output circuit having low and high sides, with a current controlling circuit coupled to the high side of the H-bridge output circuit and a current monitoring circuit coupled to the low side of the H-bridge output circuit. A bootstrap design or a DC isolating circuit or circuit element may be used in the current controlling circuit.

摘要： A connector apparatus for a medical device includes a cylindrical core of nonconductive material, a beam of conductive material, and a sleeve of conductive material. The cylindrical core includes an outside surface, an inside surface, a hollow center having a cross sectional area, and a slot opening in the cylindrical core extending from the outside surface to the inside surface. The beam is placed in the slot opening in the cylindrical core, wherein the beam reduces the cross-sectional area of the hollow center of the cylindrical core. The sleeve of conductive material is placed over the outside surface of the cylindrical core.

摘要： Systems and methods for detecting cardiac arrhythmias such as atrial tachyarrhythmia (AT) are discussed. An exemplary system includes an arrhythmia detector circuit that can receive physiologic information sensed from a patient over time, detect an arrhythmia onset when the physiologic information during a first time period satisfies an onset condition, and in response to the detected arrhythmia onset, detect an arrhythmia termination when the physiologic information during a second time period, subsequent to and longer than the first time period, satisfies an exit condition. An arrhythmia episode can be detected based on an arrhythmia duration between the detected onset and termination. The detected sustained arrhythmia episode can be provided to a user or a processor for further processing.
