    Abstract: A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent.

    Abstract: Systems and methods for coating medical devices are provided that allow for relatively precise control over the deposition area and coating uniformity with improved efficiency. A microdrop source is used to provide a flow of coating microdrops. A charging electrode disposed near the outlet of the coating source gives each microdrop an electrostatic charge. As the microdrop travels toward the medical device to be coated, a control electrode alters the trajectory of the microdrop. The invention can include a scanner to scan or image the medical device as the coating is applied and a control system to adjust parameters of the deposition process based on information provided by the scanner.
