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.

Abstract: A medical appliance or prosthesis may comprise one or more layers of electrospun nanofibers, including electrospun polymers. The electrospun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Electrospun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis.

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.

Abstract: Medical appliances may be formed of multilayered constructs. The layers of the constructs may be configured with various physical properties or characteristics. The disposition and arrangement of each layer may be configured to create an overall construct with a combination of the individual properties of the layers. Constructs may be used to create vascular prostheses or other medical devices.

Abstract: Fibrous materials and methods of manufacturing fibrous materials are disclosed. In particular, this application discloses methods of making and processing serially deposited fibrous structures, such as serially deposited fibrous mats. Serially deposited fibrous mats may be used in implantable medical devices with various characteristics and features. Serially deposited fibrous mats of various mat thickness, fiber size, porosity, pore size, and fiber density are disclosed. Additionally, serially deposited fibrous mats having various amounts of fiber structures (such as intersections, branches, and bundles) per unit area are also disclosed.
