  • Patent number: 11083874
    Abstract: A catheter has a double-action retention mechanism with (a) one retention mechanism having a reinforced retention body transformable into a deployed flower-like configuration when the catheter is inserted in the bodily cavity, and (b) a stabilizer securing the catheter to a patient's body to maintain a stable position. The retention mechanism for securing the catheter in the bodily cavity is configured with a thickened or reinforced wall portions of the retention body. The inner channel of the catheter body is wider than conventional catheters, thus attaining better drainage and better fluid flow. Due to the reinforced flower configuration, an inadvertent removal of the catheter with the flower configuration fully deployed will afflict no significant damage.

  • Patent number: 11040131
    Abstract: A method for filling and venting a device for extracorporeal blood treatment is disclosed, such as a patient module in a heart-lung machine, without attached patient. A filling liquid from a filling liquid container located higher than the device flows by gravity via a venous side of the system into a reservoir and flows onwards into a blood pump located at the lower end of the reservoir, wherein a first controllable valve (HC1) for a venting line of a filter is opened and, after the response of an upper filling level sensor in the reservoir, is closed. An upper level of the filter is positioned higher than the upper filling level sensor, and a start-stop motion of the blood pump is performed, as a result of which a stepped flooding of the filter is made providing for an advantageous de-airing of the device.
