    摘要: Various different implementations of lead systems are disclosed for use with implantable stimulation systems. Generally, the lead systems incorporate, within an elongate lead body, one or more electrical conduits that connect to one or more distal electrodes, and a liquid-filled pressure transmission catheter lumen that extends proximally from a distal entry port. Use of the lead systems allows accurate pressure sensing at a location near where the electrodes are positioned. In addition, a defibrillator lead is disclosed having such features, and a system using that lead is capable of directly monitoring pressure within a heart chamber, and using that information to confirm the delivery of a defibrillation pulse.

    摘要: An amount of fluid in a thoracic or other region of a subject may be monitored by internally injecting an electrical energy stimulus (e.g., constant voltage source) through the region, detecting voltage resulting from the electrical energy stimulus, and calculating a fluid volume indicative signal. The injected energy stimulus creates a first lead field. The responsive voltage is detected using an electrode configuration that defines a second lead field, which is arranged in a negative sensitivity configuration with respect to the first lead field at the region being monitored.

    摘要: A cardiac rhythm management (CRM) system detects tachyarrhythmia using cardiac local impedance indicative of cardiac local wall motion. A cardiac local impedance signal indicative of an impedance of a cardiac region is sensed by using a pair of bipolar electrodes placed in that cardiac region. Tachyarrhythmia such as VF is detected by analyzing one or more cardiac local impedance signals sensed in one or more cardiac regions.

    摘要: Changes in fluid volume in a thoracic region, such as the lung, are detected by internally injecting a current through the region, detecting an induced voltage on the skin of the patient, and calculating an impedance value. A method for performing such a measurement includes injecting an electrical current between first and second internal electrodes that are implanted in the body and that are positioned such that a portion of the injected current flows through at least a portion of the region. The method also includes measuring a voltage between first and second external electrodes attached to an external surface of the skin of the body. The measured voltage is induced by the injected current. The method also includes calculating an impedance by taking the ratio of the measured voltage and the injected current, wherein the calculated impedance is related to the volume of fluid in the region.

In one embodiment, the invention provides an electronic implantable device programmer having a computer processor, and a display screen configured to display information based on signals from the computer processor. The programmer also includes an input device, and a wireless transmitter controlled by the computer processor. The programmer display and input give the operator the option of programming an implanted electronic device in a cautery-safe mode. With this input, from the operator, instructions are provided in the programmer to transmit a signal from the wireless transmission device to the implanted electronic device to program the electronic device to be in a dedicated bipolar mode where electrical noise produced when operating an electro-cautery device during and medical/surgical procedure does not interfere with operation of the electronic device.

    摘要: An apparatus comprises a first impedance sensing circuit, a second sensing circuit, and an impedance-based cardiac dyssynchrony detector. The impedance sensing circuit senses an intracardiac local impedance signal that is indicative of a cardiac local wall motion of a first cardiac region from an implantable first bipolar pair of impedance sensing electrodes. The second sensing circuit is configured to produce a second sensor signal indicative of cardiovascular activity. The impedance-based cardiac dyssynchrony detector is configured for detecting cardiac dyssynchrony using a relationship between the first intracardiac local impedance signal and the second sensor signal. Other apparatuses and methods are disclosed.
