  • Patent number: 11524096
    Abstract: A first alternative to a composition for preventing or retarding degradation of a functional coating on a medical device includes an antioxidant selected from gallic acid or a derivative thereof. A second alternative to a composition for preventing or retarding degradation of a functional coating on a medical device includes carboxymethyl cellulose or a derivative or salt thereof. The use of the compositions for preventing or retarding degradation of a functional coating on a medical device from reactive species generated during exposure of radiation, and a wetting agent comprising the compositions, are also provided. The wetting agent prevents or retards the hydrolytic degradation of the coating during the intended shelf-life of the wetted coated product.

  • Patent number: 11400257
    Abstract: A catheter may include a tubular member having a lumen and an outer surface, a sleeve configured to be positioned in the lumen in a retracted configuration and to evert over at least a portion of the outer surface in an everted configuration, and a filament configured to retract the sleeve into the retracted configuration. The catheter may include an aperture proximal of a distal end, where the filament extends through the aperture from the lumen. A pull member may be on a distal end of the filament. The filament may be looped, coiled, and/or bunched in the catheter when the sleeve is in the retracted configuration. A shuttle may be attached to a distal end of the sleeve, where the shuttle includes a tubular member configured to maintain patency of the sleeve, and the filament engages the shuttle to retract the sleeve into the lumen.

  • Patent number: 11357952
    Abstract: A method of making a ready-to-use catheter assembly is provided, which can be immediately used by a patient. The ready-to-use catheter assembly ensures that the catheter does not suffer from a loss of quality during its shelf life and a wetting medium are provided. The method comprises: placing a catheter with an inactivated hydrophilic outer surface at least along its insertable length and a wetting medium in a catheter package; treating the catheter package with the catheter and the wetting medium with electro-magnetic and/or particle radiation while at least initially the hydrophilic outer surface at least along the insertable length of the catheter remains inactivated; and activating the hydrophilic outer surface at least along the insertable length of the catheter with the wetting medium during and/or after the radiation treatment and wherein the wetting medium decreases in viscosity when submitted to electro-magnetic and/or particle radiation.

  • Patent number: 10926009
    Abstract: A cleaning catheter insertable into a ventilation tube and an input module are provided, the input module coupled to the cleaning catheter and including (i) an inflation module, including an inflation chamber and a one-way air inlet valve; (ii) a flow regulator operable to assume first and second fluid-control states; and (iii) a mechanical user control element operable (a) to mechanically and non-electrically set the fluid-control states, (b) to assume first and second configurations, and (c) to mechanically and non-electrically increase pressure in an interior of an inflation chamber of the cleaning catheter during a transition of the mechanical user control element from the first configuration to the second configuration. The one-way air inlet valve is arranged to allow air to flow into the inflation chamber during a transition of the mechanical user control element from the second configuration to the first configuration.

  • Patent number: 10806884
    Abstract: 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.

  • Patent number: 10780245
    Abstract: 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 sterilising 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 sterilisation of the catheter is effectuated in a dry-state, ensuring that the known problems with wet-sterilisation are completely eliminated and the need for preparing complicated and expensive liquid swelling mediums are no longer required.
