Abstract: Economical heavy concrete weight coating is used as a weight coating for submarine pipes. The developed economical heavy concrete weight includes steel slag and iron ore as aggregate. Steel slag can contain iron and thus have a higher density than some other types of slag. By supplementing the steel slag with iron ore as aggregate, the economical heavy concrete weight coating can have a higher density than a coating having just slag. Economical heavy concrete weight coating can have a density greater than 190 pcf.

Abstract: A systems and method for reducing coating defects on a stent may involve a support apparatus comprising wire cage for carrying a stent. The support apparatus may have no structure that extends inside the stent. A support apparatus may include a plurality of wires that pass through the stent but do not pass through the midplane of the stent. A support apparatus may contact only the proximal ends of the stent. The method may involve keeping the stent in motion during a spray coating process to prevent the stent from having a point remain in continuous contact with a support apparatus.

Abstract: A method for applying a coating to an implantable device is disclosed. The method includes positioning an implantable device relative to an ultrasonic material delivery apparatus. The implantable device is rotated at a relative speed. The relative speed may be more than 120 revolutions per minute. An application material is applied to the implantable device using the ultrasonic material delivery apparatus. The relative speed may be sufficient to reduce the size of at least a portion of droplets of the application material. A system for rotating an implantable device is disclosed. The system includes an implantable device and a rotation system configured to rotate the implantable device. A longitudinal axis of the implantable device and a longitudinal axis of a rotation member of the rotation system may be offset a desired dimension. An inside diameter of the implantable device may be larger than an outside diameter of a rotation member.

Abstract: This invention relates to a method for conducting film coating on the surface of spinning circular workpiece under action of gas pressure, and nozzle utilized in the same. Circular workpiece to be coated is held on a rotating mechanism, and a feedstock loading machine having a nozzle, which is capable of guiding redundant feedstock and overflowing in a specific direction, is set to have a 100 μm gap with the circular workpiece. When the rotating mechanism is rotated, the polymer solution is precoated on the surface of the circular workpiece, and when gas valve is opened, the polymer solution is squeezed to a predetermined thickness by an annular high pressure gas-stream formed on the periphery of a cylinder, produced from the high pressure gas released.

Abstract: A system and method allows for processing of two groups of medical devices, both groups being alternatingly spray coated within the same enclosure. The two groups repeatedly move back and forth between a spray area and a drying area which is isolated from the spray area. One group moves into the spray area as the other group moves out and into the drying area. Thereafter, the group in the spray area moves out and into the drying area and the other group moves back into the spraying area for a second coating. The alternating process may be repeated any number of times. The spray area may be located inside a sealed spray isolator enclosure and surrounded by gas discharge nozzles.
