Described are polymer particles or polymer fibers covalently bonded to N-chloroamines, N,N-dichloroamines, N-chloro sulfonamides or N,N-dichloro sulfonamides, for removing volatile organic compounds (VOCs) from a space above a wound. The removal of said VOCs is believed to be primarily or predominantly by chemical reaction of the VOCs with the N-chloro or the N,N dichloro group as covalently attached to the polymer. In particular, the functionalized polymer particles or polymer fibers are part of a wound dressing and have the functionality to control, in particular reduce, odor emanating from wounds, without interacting with the wound. The described dressings can be advantageously used, in particular, in the treatment of chronic wounds or infected wounds.

Embodiments of the present disclosure provide a drainage apparatuses with scar gradient control capabilities for degradable glaucoma and methods of making the same cross-reference to related applications, comprising a long-strip-shaped drainage sheet with a uniform overall cross-sectional size, wherein the drainage sheet is made of a biodegradable material, an outer surface of the drainage sheet is provided with a drainage gap that penetrates through opposite sides of the drainage sheet, an outer surface of the drainage sheet is coated with a biodegradable surface coating, and the surface coating carries an anti-scarring drug, wherein the anti-scarring drug is configured to be gradually released as the surface coating degrades, and a distribution concentration of the anti-scarring drug within the surface coating varies in a non-monotonic manner.

A surgical device includes a substrate and a first coating that covers at least a portion of the substrate. The first coating includes a first polymer. The first coating having antibiotics dispersed in the first polymer such that the first polymer releases the antibiotics as the first polymer degrades. A second coating covers at least a portion of the first coating. The second coating includes a second polymer. The second polymer includes an alginate. The second coating has a hemostatic agent dispersed in the second polymer such that the second polymer releases the hemostatic agent as the second polymer degrades. The hemostatic agent is selected from epinephrine, tranexamic acid, chitosan and oxidized regenerated cellulose. In some embodiments, systems and methods are disclosed.

A bone graft composition comprising a calcium phosphate putty is provided. A method of repairing a bone defect in a patient by applying the bone graft composition is also provided.

The disclosure provides hyaluronic acid (HA) gel formulations and methods for treating the appearance of the skin. The formulations contain hyaluronic acid and at least one additional ingredient. Methods for treating lines, wrinkles, fibroblast depletions, and scars with the disclosed composition are provided as well.

Disclosed are adjustable intraocular lenses and methods of adjusting intraocular lenses post-operatively. In one embodiment, an adjustable intraocular lens can comprise an optic portion and a peripheral portion. The peripheral portion can comprise a composite material comprising an energy absorbing constituent and a plurality of expandable components. A base power of the optic portion can be configured to change in response to an external energy directed at the composite material.

Biodegradable, cross-linked polymer particle embolics and methods of making the same are described. The particle embolics can be used as embolization agents.

The present subject matter relates to poly(melamine-silicate) derivatives as biocidal disinfection and decontamination agents, and to methods for their production and use. More specifically, the subject matter relates to halogenated adducts of poly(melamine-silicate) with metal oxides.

Described are polymers and methods of forming and using same.

A bone graft composition comprising a calcium phosphate putty is provided. A method of repairing a bone defect in a patient by applying the bone graft composition is also provided.
