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.

The invention relates to bulking agents and apparatus and methods for using the disclosed bulking agents. The bulking agents can be used to treat such conditions as urinary and fecal incontinence, gastro-esophageal reflux, aneurismal blockages, and cosmetic deformities. The invention also relates to an injection method that reduces the injection pressure required to place the bulking agents.
