Abstract: A system and method to map a biological tissue of alternating electrical polarity having a boundary between a depolarized portion and a polarized portion is provided. The system includes a computer, a transducer probe, and a receiver. The transducer probe is in communication with the computer and configured to transmit acoustic waves at a frequency through the biological tissue of alternating electrical polarity. The receiver is in communication with the computer and operable to detect a variation in an electrical activity at approximately the frequency of the acoustic waves. The computer creates a display of at least a portion of the variation in the electrical activity at approximately the frequency of the acoustic waves.

Abstract: A monitoring system and method for monitoring signals from an implantable medical device are disclosed. The monitoring system and method include a monitor configured to detect a radio frequency artifact from the signals of the implantable medical device and circuitry for processing the radio frequency artifact from the signals of the implantable medical device.

Abstract: A method and apparatus for acquiring pulse oximetry and electrocardiogram signals from an appendage of a patient. The apparatus can include a substrate that can be attached to the appendage of the patient, an emitter coupled to the substrate, a detector coupled to the substrate, and an electrode coupled to the substrate. The apparatus can generate a blood oxygen saturation output signal based on radiation received by the detector. The apparatus can also generate a reference or non-reference electrocardiogram signal. The apparatus can include a neural-muscular transmission device.

Abstract: A method and an apparatus for use in monitoring are disclosed. The method and system involve the use of a mathematical model. The method and system are particularly useful in the field of patient monitoring when using a physiological mathematical model. A mathematical model can be used to identify an abnormal condition. The mathematical model can also be used to generate an alarm. Also, the mathematical model can be used to generate a suggested treatment for correcting an abnormal condition if an abnormal condition should arise, especially abnormal conditions requiring relatively immediate attention.

Abstract: A medical implant valve, for example, a glaucoma valve, is configured to be non-invasively adjustable. A rotor is operatively coupled to the valve to enable the position of valve to be adjusted between an open and closed position; the rotor being responsive to a magnetic field. An external instrument is used to control rotation of the rotor.
