  • Process of making a stent
    Patent number: 9655710
    Abstract: 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.

  • ROTATIONAL SPUN MATERIAL COVERED MEDICAL APPLIANCES AND METHODS OF MANUFACTURE
    Publication number: 20150352826
    Abstract: A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.

  • Drug-eluting rotational spun coatings and methods of use
    Patent number: 9198999
    Abstract: Drug-eluting rotational spun coatings that include one or more therapeutic agents may be used to coat a medical device. The medical devices include, for example, balloon catheters, vascular grafts and stents, which are coated with drug-eluting rotational spun materials that may be used to deliver a therapeutic agent to a target tissue or body lumen.
