| 20090144299 | Data storage method - A method for storing data in a database. The method uses configuration data defining an entity and a condition associated with the entity. The method comprises processing a plurality of data items, said processing including determining for each data item whether said condition is satisfied by one of said plurality of data items. If said condition is satisfied by one of said plurality of data items, creating an instance of said entity, said entity being associated with said one data item. | 06-04-2009 |
| 20110109651 | METHODS AND SYSTEMS FOR DETERMINING EFFICACY OF MEDICAMENTS - A method and apparatus for determining the efficacy of a medicament for the treatment of wounds or scars. The method comprises selecting first and second scarring site portions wherein said first scarring site portion has been treated with said medicament. A pair of images comprising a first image of said first scarring site portion and a second image of said second scarring site portion is generated, and the pair of images is displayed. A recording element comprising first and second recording portions is provided, wherein said first recording portion comprises a plurality of first points indicating that scarring in said first image is less severe than scarring in said second image, and said second recording portion comprises a plurality of second points indicating that scarring in said second image is less severe than scarring in said first image, each of said first and second points having different associated values. Data identifying one of said points is received and used to determine the efficacy of said medicament. | 05-12-2011 |

| 20110265798 | MEDICAL DEVICE TUBE HAVING SPACED LUMENS AND AN ASSOCIATED PORTED ADAPTER - Various embodiments of a tracheal tube having spaced lumens and an associated ported adapter are provided. The lumens of the tracheal tube are spaced around the circumference of the tracheal tube to facilitate evacuation (e.g., suctioning and blowing) and other applications at various locations around the circumference of the tracheal tube. The ported adapter includes lumen extensions that may be inserted into the lumens of the tracheal tube, thereby forming a connection between the ported adapter and the tracheal tube. More specifically, hollow ports extending through the lumen extensions and the body of the ported adapter facilitate connection of the lumens of the tracheal tube with external equipment such as, for example, evacuation equipment for suctioning and blowing into and out of the lumens of the tracheal tube. | 11-03-2011 |

| 20110023875 | CONNECTOR FOR COUPLING A TRACHEAL TUBE TO AN AUXILIARY DEVICE - Various embodiments of a connector assembly are provided to removably couple a proximal end of a tracheal tube to components associated with a ventilator or an anesthesiology machine The disclosed embodiments include a compression fitting, which creates an airtight seal between walls of the tracheal tube and components of the compression fitting, thus allowing air to flow to and from a patient. | 02-03-2011 |
| 20120024293 | MEDICAL DEVICE TUBE HAVING SUCTION LUMEN AND AN ASSOCIATED SUCTIONING SYSTEM - Various embodiments of a tracheal tube having a suction lumen are provided. For example, the suction lumen may be associated with two spaced apart pressure transducers, whereby a pressure drop between the transducers indicates that the suction lumen is free of blockages and a characteristic lack of pressure drop and/or particular pressure curve is indicative of a blockage. In addition, embodiments may include a tracheal tube with sensors configured to sense a buildup of secretions. The sensors may be located proximate to an opening in the suction lumen. In other embodiments, a blockage-clearing system for a suction lumen may be provided that blows air into the suction lumen to clear blockages. In particular, in certain embodiments, the blockage-clearing system may operate to create its own pressurized air source by utilizing the pressure change created in the suction line by a blockage. | 02-02-2012 |

| 20110146689 | CUFFLESS TRACHEAL TUBE - According to various embodiments, a tracheal tube ventilating device includes a sealing portion near a distal end of the tube. The sealing portion has an electroactive polymer configured to undergo a clinically effective change in volume, thickness, or both upon application of an electrical potential. Such a change in volume, thickness, or both enables sealing of the device against an inner surface of a trachea while permitting the free passage of ventilating gas through the tube. In addition, at least one electrical conductor is coupled to the electroactive polymer and is configured to apply the electrical potential. | 06-23-2011 |
| 20110290254 | TRACHEAL TUBE WITH CONNECTOR INSERT - A tracheal tube assembly includes a connector body, a cannula extending from the connector body, and an insert that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has a tapered upper end that fits between conforming tapered sections of the connector body inner surface and the insert. The insert may include features to prevent rotation of the cannula as well as rotation of the insert in the connector body. Features of the insert and connector body may also interface to mechanically retain the insert in the connector body. Different sizes of cannula may be accommodated by different inserts, while using the same or different connector bodies. | 12-01-2011 |
