    摘要: Embolic protection aspirators and methods for extracting debris from the vasculature during interventional procedures are provided. One such system may include an aspirating filter delivery catheter having a filtration device, an operable end cap, and a plurality of aspiration ports. The delivery catheter may be fluidly coupled to a suction providing means for extracting debris while traversing a target site for distal delivery of the filtration device. Another such system may include an aspirating filter retrieval catheter having an aspiration lumen and a balloon. The aspiration lumen may be fluidly coupled to a suction providing means for extracting debris from the filtration device prior to and/or during retrieval of the filtration device. By inflating the balloon to partially or fully restrict blood flow, suction pressure proximal of the filtration device may be increased to enhance debris extraction.

    摘要: Method and system for aligning a clock signal to parallel data are described. According to one embodiment, a clock shifting circuit shifts an incoming clock signal relative to an incoming data signal, and a data clocking circuit uses the shifted clock signal to reclock the incoming data signal. The clock shifting circuit may comprise a phase locked loop (PLL) coupled with multiple D flip flops (DFFs) connected in series. Divisional combinatorial logic may be disposed between DFFs in the series. Data clocking circuits may comprise one DFF to reclock each incoming data bit, a pair of DFFs to reclock each incoming data bit, or other circuits such as true-complement blocks to serve as local oscillators to mixers. Multiple shifted clock signals may be produced, such as those shifted 60, 90, 120, 180, 240, and 270 degrees relative to the incoming clock signal.

    摘要: A surgical suction nozzle for removing surgical debris and vomitus from unconscious patients in a surgical operative field that is highly resistant to clogging.An oval-shaped opening forming the suction tip is circumscribed by a raised ridge inward of the opening. A plurality of small apertures inward of the raised ridge circumscribes the nozzle, which is placed into the mouth during surgery. The suction nozzle is angularly related in three cylindrical segments to prevent any encumbrance to the surgeon.A suction control hole located on the medial segment of the suction nozzle allows the surgeon to control the suction pressure during the operation. The proximal end of the suction nozzle is beveled to be connected to a suction tube which transports surgical debris to a vacuum collection jar via a suction pipe in the cap of the jar. A debris removal pipe in the cap of the jar is connected to a vacuum tube leading to the vacuum line service outlet found in the surgery room.
