  • Patent number: 9055959
    Abstract: An ablating device has a cover which holds an interface material such as a gel. The cover contains the interface material during initial placement of the device. The ablating device may also have a removable tip or a membrane filled with fluid. In still another aspect, the ablating device may be submerged in liquid during operation.
    Type: Grant

  • Publication number: 20110230932
    Abstract: A device and method for treating a subject is provided where electrical stimulation may be separately provided to each hemidiaphragm to cause diaphragm contraction. Fatigue may be avoided among other possible benefits. Each hemidiaphragm may also be stimulated with different stimulation parameters. Stimulation may be smoothly transitioned between hemidiaphragms. Such stimulation may provide an increase in functional residual capacity or other therapeutic effects.

  • Patent number: 7069069
    Abstract: An implantable cardiac device and method provides for monitoring a progression or regression in heart disease during an extended time period. A sensor generates an electrogram signal representing electrical activity of a patient's heart. From the generated electrogram signal, a processor determines morphology measurements wherein the morphology measurements indicate a progression or regression in the heart disease. The morphology measurements are stored in a memory during the extended period of time. A telemetry circuit transmits the stored morphology measurements to an external receiver for retrieval or display. The morphology measurements may be of electrogram intrinsic activity or evoked response activity characteristics.

  • Patent number: 5385578
    Abstract: An improved endocardial lead for electrocardial stimulation includes a sleeve that has a face surface. A conductor fitted into the sleeve, such that a distal end of the conductor passes completely through the sleeve, past the face surface, is electrically and mechanically connected to the face surface of the sleeve by mechanical means, e.g. crimping, and/or through the application of heat, e.g. welding or brazing. An electrode is integrated with the sleeve along an outer sleeve surface. A highly reliable, redundant joint is thereby provided between the sleeve and the conductor that secures the conductor against movement and therefore minimizes stress placed on the conductor, preventing fatigue to the conductor at the joint.
