Abstract: According to an aspect of the present invention, a stent is provided, which contains at least one filament that has a longitudinal axis and comprises a bioabsorbable polymeric material. Polymer molecules within the bioabsorbable polymeric material are provided with a helical orientation which is aligned with respect to the longitudinal axis of the filament. The stent is at least partially bioabsorbed by a patient upon implantation or insertion of the stent into the patient.

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.
