摘要: A stent or other prosthesis may be formed by encapsulating a scaffold or frame with a polymer coating. The polymer coating may consist of layers of electrospun polytetrafluoroethylne (PTFE). Electrospun PTFE of certain porosities may permit endothelial cell growth within the prosthesis. The stent may be applicable to stents designed for the central venous system, peripheral vascular stents, abdominal aortic aneurism stents, bronchial stents, esophageal stents, biliary stents, or any other stent.

摘要: An improved process for forming a polymer mat is described. The process of electrospinning polymer fibers includes providing an apparatus having a charge source, a target a distance from the charged source and a slot die having a spinning edge with a slit. The spinning edge has a radius of curvature between 5 cm and 100 cm. The method further includes providing a polymeric preparation (solution, dispersion, suspension, or melt) to the slot die and applying an electric field to a part or the whole apparatus or polymeric preparation. When the electric field is applied, a plurality of Taylor cones are produced with jets that stretch the polymeric preparation into a fibrous structure that can be collected on a target surface.

摘要: A method of preparing antimicrobial-containing polymeric products is provided, the method involving electrospinning a dispersion comprising a dispersible polymer, a fiberizing polymer, and one or more antimicrobial agents. The electrospun material is heated to remove solvent and the fiberizing polymer, giving a nonwoven polymeric material having antimicrobial agent incorporated therein. The material can be in the form of, for example, a non-woven sheet, tube, or covering.
