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:
There are provided a golf ball having a paint coating that is prevented from being unevenly distributed over the ball surface, and a method and apparatus for manufacturing the golf ball. The method for manufacturing the golf ball comprises the steps of coating the surface of the golf ball with paint in a painting section; transferring the coated golf ball from the painting section to a drying section; and drying the coated golf ball in the drying section. The transferring step comprises attaching the coated golf ball to a moving unit by suction in the painting section; moving the moving unit to which the golf ball is attached by suction from the painting section to the drying section; and blowing gas to the golf ball toward the direction opposite to the suction direction for attaching the golf ball to release the golf ball from the moving unit in the drying section.
Abstract:
A coating solution that contains 10 to 20% by weight of epoxy resin serving as a thermosetting resin, 20 to 30% by weight of MoS2, and 5 to 10% by weight of graphite, with a remainder thereof constituted by an organic solvent, is sprayed onto a wrap portion side face of an orbiting scroll from a spray nozzle . While spraying the coating solution, the orbiting scroll is rotated on a rotating table and the spray nozzle is moved along a rectilinear movement path toward a radial direction outer side of the orbiting scroll while maintaining an attitude thereof from the start of the spraying process. After applying the coating solution, the coating solution is dried by baking, whereupon a break-in operation is performed. As a result, an elastic coating is formed at a coating thickness that enables elastic deformation in accordance with a clearance between the wrap portion side faces.
Abstract:
A can coating machine control system includes a coating control signal that functions as a go/no-go signal based on a plurality of monitored conditions such as can in position, vacuum pressure, gun in position, guard in position and speed condition. Local pressure regulation of the coating material in the spray gun is provided along with optional control of the material temperature. Local pressure regulation allows for optional spray weight control based on a wrap number derived from speed and gun spray-durations. A CAN to CAN network buffer is provided as well for primary network isolation. A gun control circuit may be used to select specific gun drive signals and to adjust gun drive signals based on real-time feedback of the actual spray duration.
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.
Abstract:
In a method for forming an electrolyte film on an electrode surface, the liquid electrolyte is sprayed into a cavity to form an electrolyte mist; the electrolyte mist exits the cavity through an opening and then flows across the electrode surface, which is directed downward at an angle behind the opening, whereby an electrolyte film is formed on the electrode surface and wherein the thickness of the electrolyte film is set by means of the angle of inclination of the electrode surface. A corresponding device includes an electrolyte tank communicating with a mist chamber for accommodating sprayed electrolyte by means of a spraying apparatus, wherein the mist chamber comprises a mist outlet. Furthermore, a retainer for fixing the electrode surface at a specifiable angle of inclination is provided, so that electrolyte mist, which can exit through the mist outlet, flows across the electrode surface to form an electrolyte film.
Abstract:
Apparatus and methods are configured to coat a medical device, such as a stent, with a beneficial medicinal agent using one or more liquid feeds and one or more micromist nozzles. In one implementation, an agent coating rig includes a vertical adjustment means, a rotation means, and a traverse adjustment means for moving a medical device along virtually any point on an x or y axis. In additional or alternative implementations, the agent coating rig can further include a secondary horizontal adjustment means that allows adjustment along virtually any point on a z axis. Furthermore, methods and apparatus are provided for distributing the beneficial agent on the medical device, including delivering the beneficial agent efficiently over time.
Abstract:
The invention relates to a component manipulator for the dynamic positioning of a substrate to be treated in a thermal treatment process, wherein the component manipulator includes a main drive axle rotatable about a main rotary axis, a connection element and a substrate holder connectable to the connection element. In accordance with the invention the connection element is a ceramic connection element and a connection segment of the substrate holder is connectable to the connection element in a pull resistant and rotationally fixed manner by means of a plug and rotate connection with regard to a connection axis (V) of the plug and rotate connection and the substrate holder (5) is arranged rotatable about the connection axis (V). The invention further relates to a coating method, to a coating apparatus, as well as to the use of a component manipulator.
Abstract:
A method of coating a stent comprises contacting a first axial portion of a stent with a support element, such that a second axial portion does not contact the support element or any other support element, applying a coating material to the second axial portion, and inhibiting or preventing application of the coating material on the first axial portion. A shuttle sheath can be used to push the stent off the support element.
