  • Publication number: 20210013574
    Abstract: An apparatus includes a signal splitter configured to receive an input signal for transmission and to split the input signal to form two or more sub-signals. The apparatus further includes a first amplifier configured to generate a first amplified sub-signal, a second amplifier configured to generate a second amplified sub-signal, a first launcher coupled to the first amplifier and to a waveguide, and a second launcher coupled to the second amplifier and to the waveguide. The first and second launchers are coupled to the waveguide such that a first radiative signal generated by the first launcher responsive to the first amplified sub-signal and a second radiative signal generated by the second launcher responsive to the second amplified sub-signal are combined in the waveguide to form a transmission signal corresponding to the input signal.

  • Publication number: 20200318102
    Abstract: The invention provides a method of selecting a representational sample of nucleic acid sequences from a complex mixture. The method includes: (a) contacting a complex mixture of nucleic acids under conditions sufficient for hybridization with a population of capture probes complementary to one or more nucleic acids comprising a predetermined portion of the sequence collectively present in the complex mixture to form hybridization complexes of the one or more nucleic acids with the population of probes, the population of capture probes being attached to a solid support, and (b) removing unhybridized nucleic acids to select a representational sample of nucleic acids having a complexity of less than 10% but more than 0.

  • Publication number: 20190143099
    Abstract: One embodiment is a lead introducer including an outer needle, an inner needle, a splittable member, and an annular seal member. The outer needle, inner needle, and splittable member each include a body and hub. The splittable member fits over the outer needle body and the inner needle body and can be separated longitudinally. The splittable member hub receives at least portions of both the inner needle hub and the outer needle hub within the splittable member hub. The annular seal member is formed by either a) the inner needle hub or b) a combination of the inner needle hub and outer needle hub. The annular seal member forms a fluid-resisting seal with the interior surface of the splittable member hub when the portions of the inner needle hub and outer needle hub are received within the splittable member hub.

    Abstract: An electrical stimulation lead includes at least one anchoring unit and each anchoring unit includes a lead attachment element. Some anchoring units include one or more anchoring fins attached to the lead attachment element and extending away from the lead attachment element when in a deployed position for contact with patient tissue to anchor the lead within the patient tissue. Each anchoring fin also has a retracted position in which the anchoring fin folds down and lies next to the lead attachment element. Other anchoring units include one or more anchoring tabs defined by the lead attachment element. Each anchoring tab is partially separated from a remainder of the lead attachment element by at least one cutout and extends away from the remainder of the lead attachment element when in a deployed position for contact with patient tissue to anchor the lead within the patient tissue.
