  • Patent number: 12193679
    Abstract: A polymeric surgical ligating clip is provided having curved leg members joined by a resilient hinge. A leg member includes a flexible rib protruding from a vessel clamping inner surface and extends longitudinally between the proximal and distal end portions of the leg member. The flexible rib defines a channel extending transversely through the rib along a majority of said length. The flexible rib can collapse and provides better retention of the clip on a vessel. The clip can contain a flexible rib on both legs in an interlocking fashion. Or a plurality of teeth can protrude from a second vessel clamping inner surface of a second leg member. The plurality of teeth can include first and second rows of teeth extending longitudinally on the second leg member, transversely separated from each other on opposite sides of a centerline of the clip.

  • Patent number: 12023041
    Abstract: A clip applier may be configured to apply a surgical clip and have a pair of jaw members. Each of the jaw members may have an inner surface and a stabilizing member extending from the inner surface. Each of the jaw members may be configured to engage a distal portion of a leg member of the surgical clip. The stabilizing members may be configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip. An inner portion of each of the stabilizing members may be spaced apart from the opposing jaw member in an open configuration, and each of the jaw members may have a channel on the inner surface to receive the opposing stabilizing member in a closed configuration.

  • Patent number: 7167693
    Abstract: A feed forward power amplifier system and method identify active channels across a frequency band to suppress unwanted intermodulation distortion (IMD) products in a communications signal such as a single- or multi-carrier communications signal. A scanning receiver identifies at least one active channel in a frequency band, and identifies at least one portion of the frequency band likely to include IMD products based upon the identified active channel(s). Based upon the identified portion of the frequency band, IMD products are suppressed from the communications signal, e.g., by controlling the magnitude and/or phase of a suppression signal mixed with the communications signal.

  • Patent number: 6937482
    Abstract: A power feedforward amplifier uses integral cavities to provide RF isolation between subcircuits of the power amplifier. The chassis includes a main chassis body and a lid structure adapted to couple with the chassis body and define the subcircuit cavities. The inner lid includes an amplifier dividing wall and interstage walls adapted to isolate the main and error amplifier subcircuits of the feedforward power amplifier and further to isolate individual components of the subcircuits. In one embodiment, the amplifier subcircuits are mounted on a single circuit board and isolated from each other by the dividing wall. A delay line subcircuit portion is integral with the main chassis body and is coupled beneath the error amplifier subcircuit to contain and electromagnetically shield a delay line filter subcircuit while providing direct connection with the error amplifier.

  • Patent number: 6829471
    Abstract: A power amplifier system and method for locating carrier frequencies across a frequency band, identifying the modulation format of each carrier, and locating and suppressing undesired intermodulation distortion (IMD) products generated by the power amplifier. The system includes an amplifier for amplifying RF carrier signals in a main signal path, a variable phase shifter and variable attenuator on a feed forward path, and a tunable receiver that digitizes a portion of the frequency band to baseband. The tunable receiver includes a tunable voltage controlled oscillator which provides an oscillating frequency to a mixer and is phase-locked to a highly stable reference oscillator. The mixer downconverts a desired RF based on the oscillating frequency to IF. A filter passes only a selected portion of the IF signals, and the filter has a passband sufficient to discern both narrowband and wideband carriers and their associated IMD products.

  • Patent number: 6744312
    Abstract: The present invention provides a power amplifier system in which one or more power amplifiers may be inserted. The occupancy of ports by power amplifiers is monitored by a controller. The system has a plurality of output lines, each with different electrical line characteristics. The controller is responsive to ports becoming occupied or unoccupied by power amplifiers and routes the output signal through the output line having the electrical line characteristics that ensure an efficient signal transfer. Further, the switching configuration of the present invention eliminates the need for output signals to traverse through a switch.

  • Patent number: 6677823
    Abstract: An automatic gain compensation circuit for actively adjusting the gain of an amplifier caused by in-loop and/or out-of-loop influences on system gain. Two matched RF detectors convert pre- and post-amplified signals to input and output voltages representative of the power of the RF signals. A gain control circuit which may include a Digital Analog Converter (DAC) utilizes an offset voltage that is weighted along with the input and output voltages to produce an error voltage. The error voltage is used to drive a voltage-controlled attenuator within the amplification path. Operational amplifiers may be used in the weighting circuits for weighting the input, output, and offset voltages in order to prevent loading of the RF detector outputs and to obtain rapid settling time. During amplifier operation, the offset voltage is adjusted by a processing unit to compensate for gain changes in the amplifier due to out-of-loop temperature-related influences on system gain.

  • Patent number: 6090138
    Abstract: A prosthetic heart valve holder includes a valve holder selectively attachable with a handle assembly. The handle assembly includes a handle end, a flexible, medial segment, and a coupling member. The valve holder includes a valve coupling member and a handle receiving member. The valve coupling member may include a leaflet bias member, leaflet guards, or both. The handle receiving member includes locking tabs and receiving windows for receiving the handle coupling member. The handle receiving member also includes anti-rotation stays which serve to transfer rotational forces from the handle assembly to the valve holder. Also, alignment stays serve to properly align the handle receiving member with the coupling member so that the handle assembly and valve holder are properly coupled. The handle assembly is made from resterilizable materials so that the handle assembly may be reused. The valve holder is disposable.

  • Patent number: 4629009
    Abstract: Method and apparatus for firing perforating apparatus in a borehole. A mechanically operated firing assembly is run into the borehole on the end of a cable and latched onto a perforating apparatus. Tension is pulled on the cable. At a predetermined tension force a firing rod is automatically released and as a result of force exerted by a compression spring driven into impactment with a percussion firing head to thereby detonate the perforating apparatus. Additionally, the firing assembly can be reset by application of downward force thereto.
