    摘要: A lead and a lead system for dispersion of a cardioversion/defibrillation electrode formed of one or more small diameter defibrillation electrodes in a heart chamber and for attaching a pace/sense electrode in contact with the heart. The small diameter defibrillation electrode or electrodes extend distally from the distal end of the lead body. If multiple electrodes are employed, they are preferably biased to spread apart when unrestrained and have a cross-section size small enough to be inserted into interstices of trabeculae in the ventricular chamber. The distal ends of the defibrillation electrodes may be free of attachment to the lead body or may be attached by a weak bond to the distal portion of the lead.

    摘要: An implantable antitachyarrhythmia device having the capability of detecting multiple tachyarrhythmias, such as ventricular tachycardia and ventricular fibrillation and capable of delivering multiple therapies, such as antitachycardia pacing, cardioversion and defibrillation. In order to assist the physician in understanding the progress of the device toward detecting a tachyarrhythmia and to better understand the operation of the therapy provided by the device, the device transmits information related to these functions on a beat by beat basis, as a supplement to marker signals associated with paced and sensed heart events. The information telemetry regarding detection allows the physician to determine how the particular R--R interval preceding the telemetry has effected the internal counts or other diagnostic parameters required to accomplish tachyarrhythmia detection. Similarly, in conjunction with stimulus pulses, the device transmits information indicative of which of the available therapy regimens is presently in effect.

    摘要: An implantable cardiac pacemaker and/or cardioverter/defibrillator employing an R-wave detector which atuomatically adjusts its sensing threshold in response to R-wave amplitude. The R-wave detector produces an output which is used to indicate the occurrence of ventricular contractions, and is used to reset the timing of the pacemaker and to indicate the occurrence of ventricular contractions for purposes of activating the associated cardioverter/defibrillator. Adjustment of the threshold is disable for a predetermined period following the delivery of each pacing pulse such that in the presence of continuous pacing for a predetermined period of time, the sensing threshold is returned to a desired, lower threshold level, allowing for detection of lower level R-waves, which may be indicative of tachyarrhythmia or fibrillation. The R-wave detector disclosed also eliminates the necessity for blanking of the input of the sense amplifier following sensing of naturally occurring R-waves, without increasing susceptibility to sensing of spontaneous T-waves which occur thereafter.

    摘要: A medical electrode lead employing one or more elongated electrode coils embedded in the surface of a flexible base pad. The electrode coils take the form of space wound coils following tortuous paths over the surface of the base pad to provide a large surface area electrode. The electrode coils include a plurality of spaced, generally parallel electrode coil segments. Located intermediate adjacent the parallel electrode coil segments are grooves or pleats, molded into the base pad. These grooves or pleats provide increased elasticity of the electrode and increased ability to conform to the contours of the heart. Insulative cores taking the form of plastic tubes are located within the electrode coils to prevent tissue ingrowth between the individual electrode coils, without induly reducing flexibility of the electrode.

    摘要: Techniques are described that allow an implantable device to sense gastric data and activity data from a patient, and estimate the patient's amount of energy consumed and energy expended based on the sensed data. A system provides feedback to the patient, a family member, or a doctor about the patient's energy consumed, energy expended, and net energy. The data may be provided in table or graphical format, and may show daily or weekly energy balance data or may show a trend of the daily or weekly energy data. The patient may receive feedback by an implanted alert module that provides and audio alert or a vibration alert. In addition, data acquired by the system may be used to adjust the patient's stimulation therapy parameters.

    摘要: Methods for delivering first and second fluid compositions to a target location of a subject include delivering the first composition from reservoir of an implantable infusion pump and delivering the second composition through a catheter access port of the implantable infusion device. The access port and reservoir are fluidly coupled to a catheter having a delivery region implanted in the target region. The methods more fully realize the therapeutic potential of infusion devices having both an access port and a reservoir. Strategic use of different agents that compliment the function of each other delivered via either the access port or the reservoir can result in enhanced therapeutic potential.

    摘要: A system and method is provided to view an anatomical structure such as a blood vessel in high contrast with its surrounding tissue. The system and method may be used to produce an image of an anatomical structure using reflected electromagnetic radiation singularly scattered from target tissue. The system and method may also provide same-side illumination and detection of reflected electromagnetic radiation in a convenient integral imaging device. The system and method may also provide helmet mounted imaging technology in a single integral helmet which allows the wearer to view an anatomical structure located within a patient such that the image is continuously oriented according to the orientation of the helmet wearer's head. The system and method may also be used in the performance of venipuncture. The system and method may provide for improved contrast between any anatomical structure and its surrounding tissue for use in any imaging system.

    摘要: An adaptive, performance-optimizing communication system for communicating with an implanted medical device in which signals are transmitted and received in accordance with predetermined, interrelated operational parameters, such as transmission rate, transmitter power, and the like. Various aspects of system performance, including bit error rate in received signals, the strength of received signals, the signal-to-noise ratio of received signals, the presence of local RF noise and non-telemetry related RF signals, and the like, are dynamically monitored by the communication system, to determine whether predetermined system performance goals are being met. If it is determined that one or more system performance goals are not being met, one or more operational parameters may be automatically adjusted so that desired performance can be achieved.
