摘要: 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.

摘要: A mold for a medical device balloon has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a cone region and a body region. The cone region is heated to a higher temperature, or the mold wall is formed to deliver applied heat more efficiently to the cone region, relative to the body region of the mold.
