    摘要: Methods and systems of the present invention provide for measurement of various cardiac parameters. Methods generally involve causing a change in volume and/or pressure in a heart chamber, measuring the change, and calculating at least one cardiac parameter based on the change. Systems typically include at least one actuator, at least one sensor, and a catheter or other device for positioning at least partially in a heart chamber. In some embodiments, the system may also include a controller, such as a computer or other processor, an external actuator, an external sensor, and/or an ECG device. Methods and systems of the invention may be used to more accurately diagnose cardiac conditions in order to make more informed treatment decisions.

    摘要: Methods, apparatus and systems for enhancing cardiac pacing generally provide for measuring at least one cardiac characteristic, calculating at least one cardiac performance parameter based on the measured characteristic(s), and adjusting at least one functional parameter of a cardiac pacing device. Devices may include at least one catheter (such as a multiplexed catheter with one or more sensors and/or actuators), at least one implant (such as a sensor implantable in a heart wall), or a combination of both. Various cardiac performance parameters and/or pacing device performance parameters may be weighted, and the parameters and their respective weights may be used to determine one or more adjustments to be made to the pacing device. In some instances, the adjustments are made automatically.

    摘要: A cardiac sensor system includes implanted cardiac sensor assemblies and an external controller which receives information from the implanted sensors. The sensors permit direct measurement of a number of physiologic parameters. The external controller permits calculation of a variety of performance values based on the measured physiological parameters. Optionally, patient oxygen consumption can be measured externally and combined with the internally measured physiologic parameters in order to calculate a variety of unique performance values.

    摘要: A multiplexed medical carrier provides for sensing one or more patient parameters and/or delivering energy via separately identifiable effectors. The carrier includes a body and at least two electrical conductors coupled with at least two effectors. Effectors may be any combination of sensors, actuators or both. Sensors may measure such parameters as pressure, oxygen content, volume, conductivity, fluid flow rate, or any other chemical or physical parameters. Actuators may be used, for example, to pace a heart, stimulate muscle or neural tissue, broadcast ultrasonic energy, emit light, heat or other forms of radiation, or deliver any form of energy or substance. A method for collecting medical data from a patient includes interrogating a network of multiplexed sensors residing on parallel conductors in the patient, including addressing a first addressable sensor in the network to obtain data and addressing a second addressable sensor in the network to obtain data.
