  • Patent number: 9155550
    Abstract: A cannula assembly for use in laproscopic surgery includes a cannula having a proximal end for use in orientating the assembly into an abdominal cavity, a distal end for insertion into a patient, and a passage through which surgical instruments can be inserted. An expandable feature in the form of an anchor is located toward the distal end of the cannula and is selectively expandable and collapsible. The feature in its expanded state prevents withdrawal of the cannula. A collar is pushed distally until it releasably cinches to the outside of the abdominal cavity thereby creating an airtight seal and stabilizing the assembly. The collar has a friction fit with the cannula designed to prevent excessive force against the cavity walls.

  • Patent number: 9155455
    Abstract: Gases are smoothly and automatically switched when using two gas supply sources, that is, an air pump and a carbon dioxide gas cylinder. By using a gas supply flow rate adjusting unit, a carbon dioxide gas is supplied to an endoscope, and a gas using a carbon dioxide gas and water are delivered. When the remaining amount of the carbon dioxide gas of the cylinder is detected and the detected pressure of the carbon dioxide gas becomes less than a predetermined value, the air pump is rotated to supply pressurized air. The rotation number of the air pump is controlled, and the same amount of pressurized air is supplied as that of the supplied carbon dioxide gas. The switching to the pressurized air is automatically performed. The supply amounts before and after the switching become equal to each other, and a surgical operator does not feel any discomfort.

  • Patent number: 9095333
    Abstract: Systems and methods for discriminating between various gases, e.g., argon and helium, for enhanced safety of medical devices are provided. The present disclosure may take the form of a dedicated-use embodiment where a specific gas, helium for example, is expected, and an enabling or “Go” signal is issued when that gas is detected, or an inhibitory or “No-Go” signal when a gas is present that is not identified as helium. Alternately, a control line or input command can be used to select between helium and argon as the expected gas and then issue the appropriate “Go/No-Go” signal, depending on which gas is identified.

  • Patent number: 9095817
    Abstract: The invention relates to a device (1) for the treatment of a biological fluid, comprising at least three chambers, wherein a first chamber (3), which is provided for receiving the biological fluid, and a second chamber (7), which is provided for receiving a gas, are separated from each other by at least one gas-permeable and liquid-impermeable membrane (9), said membrane (9) being used to transfer gas molecules between the first and second chambers (3, 7), and wherein the first chamber (3) and a third chamber (13) are separated from each other by at least one liquid-permeable membrane (15) which is used to transfer one or more components between the first and third chambers (3, 13). The second chamber (7) is delimited or enclosed by the at least one gas-permeable and liquid-impermeable membrane (9) and is located inside the first chamber (3) or is substantially enclosed by the first chamber (3) such that the biological fluid surrounds the second chamber (7).

  • Patent number: 9032951
    Abstract: An aerosol delivery system is disclosed that is a single-use (disposable) continuous nebulizer system designed for use with mechanically ventilated patients to aerosolize medications for inhalation with a general purpose nebulizer, or for connection with devices usable in endoscopic procedures. The system separates the liquid reservoir from the nebulization process taking place either at the adapter hub, where it fits into an endotracheal tube (ETT), or a gas humidifier, where the aerosol may treat a gas used in an endoscopic procedure, with a multi-lumen tube configured to nebulize liquid and air at its distal end. The refillable liquid reservoir is mounted away from the immediate treatment zone, avoiding orientation issues associated with other types of nebulizers having a self-contained reservoir. The system can produce aerosols having a wide range of droplet sizes, depending upon central lumen diameter, with values of MMAD that range from 4 to 30 ?m.
