20110027334 | MULTILAYER MEDICAL DEVICES HAVING AN ENCAPSULATED EDGE AND METHODS THEREOF - The present disclosure describes a medical which includes a body defining a conduit. The body includes a multilayer wall having at least one edge. The wall including a core layer positioned between an inner layer and an outer layer, wherein at least one of the inner and outer layers encapsulates the core layer along the edge. | 02-03-2011 |
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 |
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 |
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 |
20120118294 | TRACHEAL TUBE WITH REINFORCED PROXIMAL EXTENSION - A tracheal tube includes a proximal extension between a flange member and a connector. The extension may allow for easier access to the connector. The extension is reinforced to limit bending and kinking. Reinforcement may be accomplished by a helical element that is embedded in the extension, such as between an inner cannula and an outer cover. The outer cover may be molded with a connector after placement of the reinforcing member. | 05-17-2012 |
20120227746 | TRACHEAL TUBE CONNECTOR DEVICES AND METHODS - Various embodiments of tracheostomy tube assemblies including a cannula, a cap, and a flange are provided. The cannula includes a distal end and a proximal end, the distal end being adapted to be inserted into a patient's trachea. The annular cap includes an annular body having a first surface adapted to be received into the proximal end of the cannula to retain a portion of the cap in the annular body. The flange member includes a second surface that engages the proximal end of the cannula such that the proximal end of the cannula is retained between the second surface of the flange member and the first surface of the annular cap. The flange member also includes a third surface adapted to engage an inner surface of the annular body of the annular cap to retain the flange member between the annular cap and the proximal end of the cannula. | 09-13-2012 |
20120259173 | VISUALIZATION DEVICE AND HOLDER FOR USE WITH A TRACHEAL TUBE - The present disclosure describes systems and methods that utilize a tracheal tube with an integral visualization device, such as a camera. The tracheal tube system may include a camera apparatus or other visualization device that is associated with a lumen formed in the wall of the tube. In addition, the camera apparatus may be positioned within a holder associated with a distal end of the tracheal tube that functions to hold and position the optical components of the camera relative to the tube and provides an acceptable profile for comfortable intubation. Further, the camera apparatus and its associated holder may include additional components, such as integral light sources and flushing or cleaning devices to remove any buildup from the camera or optical components. | 10-11-2012 |
20130133644 | TRACHEAL TUBE WITH FACILITY TO VIEW INNER CANNULA - A tracheal tube assembly includes an outer cannula configured to be positioned in a patient airway and an inner cannula configured to be disposed inside the outer cannula. The tracheal tube assembly further includes a flange member secured about the outer cannula, and a connector coupled to a proximal end of the outer cannula. The connector is configured to provide a view of the inner cannula, and the inner cannula and the connector form a contiguous passageway for exchanging fluid with the patient airway in operation. | 05-30-2013 |
20140182595 | Tracheostomy Tube with Cannula Connector - A tracheal tube assembly includes a cannula connector that includes a cannula connector cap coupled to a flange assembly. The flange assembly is in turn coupled to a cannula. The flange assembly includes a portion that extends through slots formed at or near a proximal end of the cannula connector cap. The flange assembly may be overmolded. | 07-03-2014 |
20140190487 | TRACHEAL TUBE WITH PILOT VALVE BALLOON GUARD - A pilot balloon assembly for a tracheal tube includes a pilot balloon guard for a pilot balloon. The pilot balloon guard includes an enclosure having walls that define an interior volume that is greater than an interior volume of a pilot balloon. The pilot balloon is received by the enclosure and inflates within the enclosure to indicate inflation of a cuff of the tracheal tube. The pilot balloon guard enclosure absorbs externally applied forces to prevent transfer of the externally applied forces to the pilot balloon. | 07-10-2014 |
