abstract "medical devices covered by spin-spun material and manufacturing methods" the present invention relates to a medical device or prosthesis that can comprise one or more layers of spin-spun nanofibers, including spin-spun polymers. the spin-spun material may comprise layers that include layers of polytetrafluoroethylene (ptfe). nanofiber meshes spun by rotation of certain porosities can allow the internal growth of tissue into the prosthesis or fixation to it. in addition, one or more cuffs can be configured to allow internal tissue growth to anchor the prosthesis. |
