    摘要: A method is provided including delivering at least one electrical signal to tissue of a patient through an electrode. The method further includes assessing whether a net charge remains on the electrode a predetermined period of time after the delivery of the electrical signal. Systems for delivering such a signal, and assessing whether a net charge remains on the electrode providing the signal, are also provided.

    摘要: An implantable medical device (IMD) may include a lead circuit including a first node configured to be coupled to a first lead that may be coupled to a first target tissue and including a second node configured to be coupled to a second lead that may be coupled to a second target tissue. The IMD may include an impedance unit that may determine at least one characteristic of coupled energy associated with the lead circuit, where the coupled energy may be produced by a source external to the IMD. The impedance unit may provide an impedance between the first node and the second node, where the impedance is selected based at least in part on a characteristic of the coupled energy. The impedance is selected to reduce the coupled energy or a negative effect associated with functionality of the IMD induced by the coupled energy.

    摘要: The present invention relates to compounds and methods which are useful in molecular investigations of target genes, as well as their encoded RNAs and protein, belonging to signature self renewal programs in leukemia and/or cancer stem cells. Data herein shows that leukemia stem cells can be generated from committed progenitors without widespread reprogramming of gene expression, and wherein a leukemia self-renewal associated signature is activated in the process.

    摘要: A method and apparatus for treatment of an eating disorder includes electrically, mechanically and/or pharmaceutically/chemically stimulating a of the vagus nerve of the lower esophagus, cardia, esophageal/cardia junction, cardia/fundus junction or upper stomach so as to induce afferent action potentials on the vagus nerve. The device may be noninvasively adjusted after implantation to provide increased or decreased restriction on the patient's gastrointestinal tract. Each stimulus may be administered as a series of programmed pulses of defined amplitude, duration and period, to evoke a responsive signal to the brain by the target nerve, effective for producing a temporary feeling of satiety in the person. An implantable stimulus generator may be operatively coupled to a nerve electrode, pressure device or chemical outlet to apply a defined signal to a selected nerve branch. The implantable stimulus generator is programmable to allow clinician programming of defined signal parameters effective to treat the eating disorder of the patient. Methods are also provided to identify electrodes nearest to a branch of the vagus nerve to apply an electrical stimulation signal with improved efficiency.

    摘要: A method and an apparatus for determining a time period remaining in a useful life of an energy storage device in an implantable medical device. The method may include measuring a voltage of the energy storage device to produce a measured voltage, and comparing the measured voltage to a transition voltage. While the measured voltage is greater than or equal to the transition voltage, the time period remaining in the energy storage device's useful life is approximated based upon a function of charge depleted. While the measured voltage is less than the transition voltage, the time period remaining in the energy storage device's useful life is approximated based upon a higher order polynomial function of the measured voltage. The transition voltage corresponds to a predetermined point on a energy storage device voltage depletion curve representing the voltage across the energy storage device over time.
