  • Patent number: 8940321
    Abstract: The present invention relates to compositions and methods useful for the treatment of ear disorders, administered to a treated ear in the form of a foam or a mousse. Administering a medicament in such forms will increase the residence time of the medicament in the ear canal, provide relatively uniform distribution of the composition, and can increase the penetration of the active pharmaceutical ingredient in the affected area, may release active substances slowly, enhance treatment effectiveness, increase compliance and is more convenient to use than currently available ear medications. The administration in the form of a foam or a mousse may preferably be provided as a metered dose, of a volume suitable to fill the ear canal.

    Abstract: A urinary anti-backflow device is provided which prevents urine from flowing back into the patient's bladder from a urine collection bag. The device comprises a flow tube having an upstream section connectable to an external urinary device secured to a patient and a downstream section connectable to a urine collection bag, a rod within the flow tube, and a stopper which moves along the rod between the downstream and upstream ends of the flow tube. When the upstream section of the flow tube is elevated relative to the downstream section, urine from the patient is free to flow through the flow tube. When the downstream section of the flow tube is elevated relative to the upstream section, urine forces the stopper against the upstream section to prevent backflow.

The shell is comprised of at least one inorganic polymer obtained by a sol-gel process, and the shell protects the active ingredient before topical application and is designed to release the active ingredient from the microcapsules following application. The composition is useful in encapsulating active ingredients, such as benzoyl peroxide, that are unstable in other formulation, or are irritating to the skin.

  • Patent number: RE40640
    Abstract: Injectable microfoam for scleroteraphy. The sclerotherapy of varices is based on the injection of liquid substances capable of suppressing them. The present invention relates to the preparation of sclerosing substances in the form of a microfoam. The microfoam is prepared with sclerosing agents, and is then injected in the vein to be treated, so that the microfoam displaces the blood contained in the vein and provides for the contact of the sclerosing agent with the vascular endothelium, with a predetermined known concentration and during a controllable time.
