  • Publication number: 20240074001
    Abstract: An aerosol delivery device having a detachable power source is provided. A control body may be coupleable with a cartridge to form an aerosol delivery device. The cartridge may contain an aerosol precursor composition and be equipped with a heating element configured to activate and vaporize components of the aerosol precursor composition. The control body may comprise a housing and a power source detachably coupled to an outer surface of the housing. A control component may be contained within the housing and configured to operate in an active mode in which the control body is coupled with the cartridge. The control component in the active mode may be configured to direct power from the power source to the heating element to activate and vaporize components of the aerosol precursor composition.

  • Patent number: 9521842
    Abstract: The use of poly(oxybutylene)-poly(oxyethylene)-poly(oxybutylene) block copolymers in pharmaceutical compositions useful for modifying the surfaces of contact lenses and other medical devices is disclosed. The present invention is based in-part on a discovery that this class of compounds is particularly efficient in wetting hydrophobic surfaces, such as the surfaces of silicone hydrogel contact lenses and other types of ophthalmic lenses, but do not induce foaming when used in conjunction with a peroxide-based contact lens disinfection regimen. Such compounds may also be useful for cleaning purposes. The use of the compounds as surfactants in peroxide-based compositions for disinfecting contact lenses therefore represents a preferred embodiment of the present invention.

  • Patent number: 9259472
    Abstract: The present invention relates to artificial tear formulations and ophthalmic formulations suitable for drug delivery. The formulations comprise galactomannans such as guar or hydroxypropyl guar and a borate source such as boric acid. The formulations further comprise a cis-diol such as sorbitol that interferes with the cross-linking of galactomannan and borate. Optionally, the formulations are substantially free of divalent cations.
