  • Patent number: 8739727
    Abstract: The medical device of the invention comprises a surface comprising at least one outermost portion and a plurality of depressions. The depressions occupy at least about 80% of the surface area of the surface. The depressions contain a coating material that preferably comprises a biologically active material and/or polymer, and the outermost portion is substantially free of any coating material. The invention is also directed to a method for manufacturing a medical device. The method comprises applying a coating material to the surface of the medical device by using at least one roller.

  • Patent number: 7785652
    Abstract: System and method for coating a medical appliance is provided. In accord with one embodiment, a system for applying a coating to a medical appliance having accessible patterned surfaces is provided. The system may include: a processor, an appliance support, and a solenoid type fluid dispensing head having an electromagnetically controlled valve. In the system, the appliance support may be adapted to hold the medical appliance and to provide direct access for a coating to contact the exposed external patterned surfaces of the medical appliance. The solenoid type fluid dispensing head in this system may move with respect to the medical appliance and may be in communication with a source of coating and with the processor. The processor in this system may contain commands that instruct the solenoid type fluid dispensing head to force coating onto the accessible patterned surfaces of the medical appliance in a pattern that correlates with the accessible patterned surfaces of the medical appliance.

  • Publication number: 20040247775
    Abstract: The present invention provides an apparatus and method that uses positive displacement of coating material using a computer controlled, motorized dispensing device. The flow rate of the dispensing device is controlled, and the positive displacement apparatus and method result in a precise amount of coating that is dispensed. The positive displacement coating apparatus and method allow for much more accurate and consistent coating from part to part. Because the positive displacement coating apparatus precisely controls the flow rate of the coating, differences in viscosity of the coating do not adversely affect the amount of the coating that is dispensed. In addition, the fluid flow path or pressure differential do not adversely affect the amount of the coating that is dispensed.
