Described herein are polymeric particles configured for intravascular delivery of pharmaceutical agents, e.g., to a diseased site, and methods of forming and using same. Preparation of these polymer particles is also described.

Methods for intravesical administration of a therapeutic agent including application of a photoactive nanogel to the mucosal surfaces of the bladder and/or intravesical application of cell-penetrating peptides. Photoactive nanogels may be aggregated by exposure to ultraviolet light, either in vitro or in vivo, to provide controlled or extended release of a therapeutic agent, such as an antibiotic.

Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The activator layer may include a copolymer of monomers with one or more covalently linked multifunctional groups.

A dissolvable medical device for protecting a corneal surface and providing lubrication and hydration to the corneal surface during ophthalmic surgery comprising: a polymeric film has sufficient dimensions to substantially cover a cornea when applied to an eye, wherein the polymeric film comprising one or more mucoadhesive polymers. The polymeric film dissolves between 15 minutes to 120 minutes to release the mucoadhesive polymers after applying the polymeric film to the eye and the polymeric film provides more effective corneal surface protection relative to a saline treatment based on Mean Green Fluorescence Index test (demonstrates corneal damage) during a simulated surgery. In addition, a kit for use in ophthalmic surgical procedures comprises 1) the at least one dissolvable medical device and 2) at least one viscosurgical viscoelastic or at least one ophthalmoscopic surgical contact lens.
