Patent number: 10500360Abstract: In embodiments of the present invention, a suction cleaning system component is provided for use in cleaning an interior of a tracheal ventilation tube when the suction cleaning system component is connected to the tracheal ventilation tube and a ventilator. Typically, the suction cleaning system component is used in a closed endotracheal suction system environment. The suction cleaning system component comprises a cleaning catheter and a manifold. The manifold comprises an obstruction element, which is moveable with respect to (i) the ventilator port and (ii) the expandable element. The obstruction element is configured to assume a plurality of states, including an obstruction state.Type: GrantFiled: August 10, 2015Date of Patent: December 10, 2019Assignee: TELEFLEX LIFE SCIENCES UNLIMITED COMPANYInventor: Oron Zachar

Patent number: 10328224Abstract: A cleaning catheter includes an inflatable element expandable into contact with an inner surface of a ventilation tube. An input module includes a flow regulator, which is shaped so as to define a suction port coupleable in fluid communication with a suction source, and a fluid port coupled in fluid communication with a pressurized fluid source. A mechanical user control element is configured to mechanically and non-electrically set at least base and inflation/suction activation states of the flow regulator. When in the inflation/suction activation state, the flow regulator effects fluid communication between the suction port and a distal suction orifice, and effects inflation of the inflatable element by fluid communication between the fluid port and the inflatable element via a fluid-delivery lumen. The mechanical user control element includes one or more user-interface elements, a single one of which is arranged to set the flow regulator in the inflation/suction activation state.Type: GrantFiled: March 14, 2016Date of Patent: June 25, 2019Assignee: TELEFLEX LIFE SCIENCES UNLIMITED COMPANYInventors: Oron Zachar, Elad Einav, Gil Yigal

Patent number: 10328237Abstract: A ready to use catheter assembly comprises a catheter package with an opening, a catheter with a shaft arranged in the catheter package so a distal end of the catheter lies in the region of the opening, and a protective sleeve which partly covers the catheter shaft, a first end of the protective sleeve fixed to the distal end of the catheter. A method for producing a ready to use catheter assembly and a ready to use catheter assembly which further reduces the risk of an accidental contamination of a catheter when pulling it out of the catheter package prior to the insertion into the urethra of a user are provided. The opening has a defined maximum opening length, a second end of the protective sleeve is releasably connected which the catheter package near the maximum opening length of the opening and the protective sleeve is in a retracted state.Type: GrantFiled: March 21, 2017Date of Patent: June 25, 2019Assignee: Teleflex Life Sciences Unlimited CompanyInventors: Ronald John Kelly, Alan Fitzgerald, Morgan Tierney, Volkmar Schulz, Bernhard Hiesch

Patent number: 10322253Abstract: A cleaning device, system and method for use with an ETT or tracheostomy ventilation tube 60, a ventilator machine 900, a source(s) 602 of fluid (for example, pressurized or unpressurized) and a source(s) of suctioning 603 is disclosed. In some embodiments, the cleaning device is useful for cleaning an inner surface of the ventilation tube 60 and/or for preventing or hindering the accumulation of biofilm thereon. In some embodiments, it is possible to clean biofilm or any other material on the inner surface 201 by delivering fluid into an interior of the ventilation tube, wiping the tube interior with a width-expanded wiping element (e.g. an inflated balloon) by longitudinal motion of the wiping element, and suctioning material out of the ventilation tube ventilation tube.Type: GrantFiled: March 29, 2012Date of Patent: June 18, 2019Assignee: TELEFLEX LIFE SCIENCES UNLIMITED COMPANYInventors: Elad Einav, Oron Zachar

Patent number: 10201681Abstract: A method of preparing a ready-to-use catheter by providing a catheter assembly that has a first compartment that includes a catheter therein. The catheter includes on at least a part of its surface an exterior coating designed to reduce the coefficient of friction after treatment with a liquid swelling medium, and a second compartment containing a liquid swelling medium. The method includes sterilizing the catheter assembly, adding the liquid swelling medium to the first compartment for wetting/activating the exterior coating of the catheter, and storing the ready-to-use catheter. By using the method according to the invention, the sterilization of the catheter is effectuated in a dry-state, ensuring that the known problems with wet-sterilization are completely eliminated and the need for preparing complicated and expensive liquid swelling mediums are no longer required.Type: GrantFiled: December 13, 2017Date of Patent: February 12, 2019Assignee: TELEFLEX LIFE SCIENCES UNLIMITED COMPANYInventor: Lars Schønfeldt

Patent number: 10143814Abstract: A cleaning catheter (200) includes fluid-delivery and suction lumens (520, 530). A flow regulator (700) defines suction and fluid ports (830, 827). A mechanical user control element (320) is configured to mechanically and non-electrically set activation states of the flow regulator (700), and transition between first and third configurations via a second configuration. When the control element (320) is in the first configuration, the flow regulator (700) blocks fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the second configuration, the flow regulator effects fluid communication between the suction port (830) and the suction lumen (530), and blocks fluid communication between the fluid port (827) and the fluid-delivery lumen (520).Type: GrantFiled: January 12, 2016Date of Patent: December 4, 2018Assignee: Teleflex Life Sciences Unlimited CompanyInventors: Oron Zachar, Elad Einav, Gil Yigal
