Publication number: 20170119494Abstract: Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a method for cleaning endotracheal tubes comprises inserting a cleaning device within an endotracheal tube while a cleaning member is in a compressed position, radially expanding the cleaning member to an expanded position within the endotracheal tube, and withdrawing the cleaning device from the endotracheal tube with the cleaning member in the expanded position.Type: ApplicationFiled: January 13, 2017Publication date: May 4, 2017Inventors: Brad E. Vazales, Arthur E. Bertolero, Ken Watson, James M. Gracy

Publication number: 20170119495Abstract: The invention relates to a dental treatment or examination system having a plurality of treatment or examination instruments and also having a supply unit coupled to the treatment or examination instruments. In this connection, the system has means to identify the contact of a selected instrument from the plurality of instruments and initializes, as a function of an identified contact of the relevant instrument, the supply unit for an operation of the instrument. Using the means to identify the contact it is thus possible to achieve a situation where the supply unit, for example, automatically makes available activation or parameterization options for the relevant instrument and/or suitable media without more extensive manipulation on the part of the user of the system being required therefor. As a result, the operation is facilitated.Type: ApplicationFiled: October 26, 2016Publication date: May 4, 2017Inventors: Richard Buerk, Johannes Sauter

Publication number: 20170119501Abstract: An orthodontic self-ligating bracket for orthodontic treatment of maloccluded teeth. The bracket includes a bracket body, a bracket door, and a spring mechanism retained by the bracket door. The bracket body has a base on the bottom side of the bracket body that is contoured to attach to a surface of a tooth, a bracket slot on the top side of the bracket body extending in a mesiodistal direction and configured to releasably retain an archwire, and a bracket groove on the top side of the bracket body extending in an occlusogingival direction towards the bracket slot. The spring mechanism includes one or more springs that are configured to contact the bracket door and the bracket body. The bracket door can thus be retained by and slidably engage the bracket body between an open position and a closed position. One or more additional active spring members may also be provided.Type: ApplicationFiled: March 25, 2016Publication date: May 4, 2017Applicant: Henry Schein, Inc.Inventors: Mark A. Payne, Colin Corey
