The disclosure concerns various devices implemented to provide a therapeutic gas rich environment to promote healing, reduce fibrosis and scar formations while maintaining anti-inflammatory, anti-thrombotic, antimicrobial, and vasodilating properties. The device generally includes a gas-donor composition that is embedded within a fibrous holding layer. Coupled to one side of the fibrous holding layer is a water-permeable layer and coupled to an opposite side of the fibrous holding layer is a gas-permeable layer. The water-permeable layer is configured to receive and communicate water to the gas-donor composition, wherein upon contact with the water, the gas-donor composition is configured to deliver a therapeutic gas through the gas-permeable layer to a treatment site of a subject.

Devices and methods for delivering oxygen and other therapeutic gases to a target, such as a tissue, a tissue-engineered construct, and a wound, in a controlled and sustained manner are disclosed.

Several embodiments of NO releasing structures are disclosed. In some embodiments, the structures are covalently modified to store and release nitric oxide. Some embodiments pertain to methods of making and use of these structures. The covalently modified polymer structures may be tailored to release nitric oxide in a controlled manner and are useful for treatment of various medical conditions.

A composition comprising an organic photoactivator, a gasotransmitter salt which converts into a gasotransmitter via electron transfer, and an electron donor which donates an electron to the photoactivator when the photoactivator is in a photo-excited state.

The present invention relates to methods for removal of dead tissue from wounds or skin using topical nitric oxide donor devices and/or compositions. In one embodiment, the present invention relates to a transdermal patch device that is designed to deliver nitric oxide. In another embodiment, the present invention relates to one or more devices and/or compositions that are designed to deliver nitric oxide and optionally one or more other compounds, where such devices/compositions include, without limitation, bandages, layered bandages, adhesive bandages, transdermal patches, creams, ointments, or a any combination of two or more thereof.

Disclosed are liquid cast biodegradable arterial stents and methods for preparing liquid cast biodegradable arterial stents. The typically includes a biodegradable polymer and may include an agent for treating neointimal hyperplasia.

Disclosed is a method for preparing a nitric oxide-generating adherent coating, comprising: preparing a buffer solution containing polyphenol compounds, organic selenium or sulfur compounds and soluble copper salts; then contacting a base material with the solution, and washing and drying to obtain a target product. The nitric oxide-generating material prepared by the method can be used for any medical device, such as an intravascular stent, or materials and any complex-shaped base material, and has the capability of scavenging free radicals and catalyzing RSNO to produce nitrogen monoxide, and also has a response function of reduced glutathione (GSH), an antimicrobial function and all the physiological functions possessed by nitrogen monoxide.

Medicament containment devices and systems as well as related methods of use for administering a medicament or therapeutic composition or agent to a subject are disclosed and described. In one embodiment, a containment device can include a containment reservoir configured to receive a medicament or therapeutic agent. The containment device can be configured to be secured to a treatment area of a subject and the containment reservoir can be loaded with the medicament or therapeutic agent for administration to the subject in a localized targeted treatment area.
