  • Patent number: 10980671
    Abstract: Drainage of body fluid from a first area of the body to a target area of the body can be accomplished by interconnecting an artificial non-blood fluid conduit with the venous and/or lymphatic system of the body. For example, an artificial non-blood fluid conduit can be inserted into the eye to fluidly interconnect the anterior chamber with a venous structure, such as an anterior ciliary vein, or lymphatic in a target location of the eye. The outflow end of the conduit can be positioned adjacent to and/or cannulated within the venous structure or lymphatic. Further, the conduit can optionally have an angiogenic material for stimulating growth of new blood vessels in the target location to fluidly interconnect the venous structure or lymphatic with the anterior chamber using the non-blood fluid conduit.

  • Patent number: 10953148
    Abstract: A plasmapheresis device includes a column or other flow mechanism in which plasma flows following separation of the plasma from cellular components like blood cells, platelets and the like. The column includes a moiety, such as an antibody, which selectively binds to galectin-3. By removing galectin-3 from the blood stream of a mammal by at least 10%, improvements in the treatment of inflammation, suppression of the formation of fibroses, and a variety of cancer treatments can be effected or improved. The device provides for multiple columns to remove a variety of elements but includes one which selectively removes galectin-3 from the blood flow. Other agents may be added to the plasma before recombination with the cellular components of the blood, and before returning the recombined flow to the patient.

  • Patent number: 10912870
    Abstract: Embodiments of negative pressure wound therapy apparatuses and methods for using such apparatuses are disclosed. In some embodiments, a negative pressure wound therapy apparatus includes a controller configured to determine a level of exudate in a canister (or a dressing) based at least in part on one or more characteristics of pressure signals generated by a negative pressure source and monitored by a pressure sensor. One such characteristic of the pressure signals can be amplitude, which may increase as a level of exudate in the canister (or dressing) increases. The canister (or dressing) can include a filter configured to become occluded in order to prevent overflow of the canister (or dressing). The controller can be additionally configured to detect and indicate a canister (or dressing) pre-full condition before the filter becomes occluded. More efficient and reliable operation of the negative pressure wound therapy apparatus can thereby be attained.

  • Patent number: 10905852
    Abstract: A urinary catheter is disclosed, comprising a tubular shaft extending between an insertable end and a discharge end, and a tip fixedly connected to said insertable end of the tubular shaft. The tip has an outer diameter which at all places is equal to or lower than the outer diameter of the tubular shaft, and is very soft, so that the hardness of the tip is equal to or lower than 60 micro Shore A.

  • Patent number: 10869959
    Abstract: A method and device treats cancer where blood from a cancer patient passes through an array of passageways within an interior of a chamber. The passageways include wells having porous membrane wall portions that enable a molecular-sized activating agent in a carrier fluid that enhances an immune response to pass through these porous wall portions. Pore size is such to allow the molecular-sized activating agent in the interior of the chamber to enter the wells yet prevents immune cells and cancer cells in the wells to pass through the porous wall portions into the interior of the chamber. Blood is retained in the wells so that it remains in contact with the immune cells and cancer cells for a predetermined period sufficient to enhance an immune response. Then the cells with an enhanced immune response are return to the patient.

  • Patent number: 10857067
    Abstract: The invention proposes a biological protection membrane which is mounted, in a device for dispensing liquid from a sterile packaging bottle, across a fluid-circulation duct, in the path of the liquid extracted from the bottle and the outside air which is drawn into the bottle. The membrane (7) is made partially of a hydrophilic material and partially of a hydrophobic material. Both the hydrophobic portion (23) and the hydrophilic portion (22) are made from a polymer base, laden in the body thereof with a biocidal agent that is active in the destruction of bacteria by the ionic oxidation effect. The circulation of fluids through the membrane (7) is organised so as to promote the ionic action on the flow of outside air in the hydrophobic material, and to drive the ionically charged active agent by the liquid passing through the membrane in the hydrophilic portion thereof.
