ELECTROSPUN PTFE COATED STENT AND METHOD OF USE |
| 摘要 |
A stent or other prosthesis may be formed by coating a single continuous wire scaffold with a polymer coating. The polymer coating may consist of layers of electrospun polytetrafluoroethylene (PTFE). Electrospun PTFE of certain porosities may permit endothelial cell growth within the prosthesis. |

1. A method of constructing a stent, comprising:
electrospinning a first tube of PTFE onto a rotating mandrel; sintering the first tube; applying a scaffolding structure around the first tube; applying a fluorinated ethylene propylene (FEP) layer around the first tube and the scaffolding structure; and applying a second tube of electrospun PTFE around the FEP layer. |
