Abstract: A nanoparticle coated hydrogel may be formed by a method of electrospraying nanoparticles on to a surface includes providing a drug and polymer combination in solvent to an inner capillary of a coaxial dual capillary spray nozzle. A coating with a drug that releases over time may be provided. Open and closed matrixes may be selectively formed to help modify time release periods.

Abstract: Devices to deliver one or more active ingredients for medical treatment may include a body of material presenting a surface including a polymer adapted to be rendered conductive such that one or more layers of electrospray particles are formable thereon or a body of conductive material presenting a surface upon which one or more layers of electrospray particles are formable thereon. A coating formed of electrospray particles may be deposited to adhere on the surface of the body of material (e.g., the coating may include one or more layers of coating material, at least one layer of the one or more layers of coating material may include an open matrix coating, the open matrix coating may include one or more active ingredients, the open matrix coating may include one or more polymers and one or more active ingredients, etc.).

Abstract: Electrospray methods and systems for coating of objects (e.g., medical devices such as a stent structure) with an open matrix coating. The open matrix coating is formed by electrospray using one or more nozzle structures each having at least an inner and outer opening. A first flow of a liquid spray composition is provided to the inner opening and a second flow of a liquid diluent composition is provided to the outer opening (e.g., the liquid diluent composition including at least one solvent, such as a composition having a dielectric constant equal to or greater than 10).

Abstract: The present invention relates to an ultrasonic cutting system including a protective sheet for protecting a cutting blade. The ultrasonic cutting system includes an ultrasonic cutting device, a base plate, and a protective device. The ultrasonic cutting device is configured to cut a material and includes a cutting blade. The base plate is configured to support the material during interaction with the cutting blade. The protective device includes a protective sheet routed over the base plate. During use of the ultrasonic cutting system, the material is routed over the protective sheet prior to interaction with the cutting blade, and the protective sheet is configured to decrease contact between the cutting blade and the base plate.
