  • Patent number: 11052170
    Abstract: The invention relates to a device for treating blood flow in an internal wound, including a handling member connected to a series of successively narrower tubes, each tube including a liquid-expandable article. The tubes can be pivotably connected to each other, allowing the tubes to conform to the contours of the wound, or fixed together. The tubes can be encased in a liquid-soluble layer that keeps the liquid-expandable article sequestered from liquids. The stepwise-tapering profile of the device allows for its insertion into the internal wound with little or no resistance until fully seated. Upon encountering liquids within the wound, the liquid-soluble layer can dissolve to expose the liquid-expandable article. When exposed to the wound liquids, the liquid-expandable element can expand in volume, providing compressive pressure against internal wound surfaces and minimizing blood loss. The tubes and the liquid-expandable element can include therapeutic agents for treating the wound.

  • Patent number: 11052176
    Abstract: A two-layer gradient coating article is provided that is operable to cause selective adhesion and directional migration of endothelial cells. The first layer includes cell-resisting polymers that repels cells, the second layer includes one layer of peptides that has affinity to and binds specifically to endothelial cells. Furthermore, the peptides are distributed in a gradient, in which attached ECs migrate towards the direction of increased concentration, thus enriching the ECs to a desired locus. The combination of a cell-repelling layer and a graded affinity peptide produces a unique result of selective adhesion, directional migration, thus local enrichment of endothelial cells. A method for using such gradient coating article and its potential use in treating cardiovascular diseases are also provided.

  • Patent number: 11052182
    Abstract: The present invention relates to a method for checking a dialyzer for the presence of a leak in the semipermeable membrane of the dialyzer, wherein the membrane divides the inner dialyzer space into a least one blood chamber and into at least one dialyzate chamber, wherein the blood chamber is flowed through by blood in the operation of the dialyzer and is in fluid communication with a blood-side line system and the vascular system of the patient, and wherein the dialyzate chamber is flowed through by dialysis fluid in the operation of the dialyzer and is in fluid communication with a dialyzate-side line system, wherein the method comprises the following steps: a) emptying the blood chamber or the dialyzate chamber of blood and of dialysis fluid respectively and keeping the fluid (blood or dialyzate) in the non-emptied dialyzate chamber or blood chamber; b) building up a test pressure by means of a gas, in particular by means of air, in the emptied blood chamber or in the emptied dialyzate chamber; and c)

  • Patent number: 11052184
    Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the spinning membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib or ridge associated with the spinning membrane that decreases the gap between the spinning membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously-collected whole blood into selected blood components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.

  • Patent number: 11052185
    Abstract: The present invention concerns a medical injection device for apportioning set doses of a preservative containing liquid drug. The injection device comprises a housing supporting a cartridge containing the preservative containing liquid drug and a needle cannula for transferring the liquid drug from the cartridge and through the skin of a user. Further, a needle shield which is axially movable in relation to the housing is also present. The axially movable shield carries a cleaning reservoir for cleaning at least the tip of the needle cannula between subsequent injections and the cleaning reservoir is preferably filled with preservative containing liquid drug directly from the cartridge upon initiation of the injection device. In order to eliminate any overpressure being built up inside the cleaning reservoir during the filling process, the cleaning reservoir is provided with an outlet configured to be permanently sealed by a user activated operation.
