In a state where a process gas including SF.sub. 6 and O.sub. 2 is supplied in a chamber, a laser light irradiator provided outside the chamber irradiates a laser light onto a substrate. At the portion of the substrate onto which the laser light is irradiated, the material that makes up the substrate is excited and converted into a gaseous substance by reacting with the process gas. The temperature of the substrate placed on a stage is kept at a predetermined temperature since a temperature adjuster supplies a chiller to a coolant flow passage provided inside the stage.

Use of Plasma in Formation of Biodegradable Stent Coating
Metallic stents are treated with a gaseous species in a plasma state under conditions causing the species to polymerize and to be deposited in polymerized form on the metallic stent surface prior to the application of a drug-polymer mixture, which is done by conventional non-plasma deposition methods. The drug-polymer mixture once applied forms a coating on the stent surface that releases the drug in a time-release manner and gradually erodes, leaving only the underlying plasma-deposited polymer. In certain cases, the plasma-deposited polymer itself erodes or dissolves into the physiological medium over an extended period of time, leaving only the metallic stent. While the various polymers and drug remain on the stent, the plasma-deposited polymer enhances the adhesion of the drug-polymer anchor coating and maintains the coating intact upon exposure to the mechanical stresses encountered during stent deployment.

Method for generating hydrogen from water or steam in a plasma
Water molecules, preferably in the form of steam or water vapor, are introduced into a plasma. The plasma causes the water molecules to dissociate into their constituent molecular elements of hydrogen and oxygen. To prevent recombining of the constituent molecular elements, the hydrogen and oxygen are separated from each other. Various devices may be employed to effect this separation. Once separated, the molecular components are prevented from recombining with each other or with other elements by using standard separation techniques normally employed for separating dissimilar gaseous species.

Infusion System for the Controlled Delivery of Therapeutic Agents
ActiveUS20140276587A1Extended shelf lifeKeep sterileMedical devicesPressure infusionDrug reservoirChemical reaction
Embodiments of the invention provide infusion systems for the intravenous or other delivery of drugs and other therapeutic agents to a patient including a human or mammal. The therapeutic agents may be dissolved in solution or comprise the solution itself. Embodiments of the systems can utilize a chemical reaction to predictably drive a flow of drug(s) through a catheter or other flow path and into the patient. More specifically, the reaction may include an acid-base reaction or any other reaction that produces a gaseous substance. The gas is produced and contained in an expandable drive balloon when the acid-base reactants are combined with a liquid. As the gas is produced, the drive balloon expands to exert pressure on a separately-contained drug reservoir which, in turn, pushes drug(s) from the reservoir into the flow path where the drug is ultimately delivered to the patient in a controlled and predetermined manner.
