Electrostatic spinning method for producing tubular fibrous structures from fiberizable material wherein the fiberizable material is collected on an electrostatically charged mandrel wherein the fiberizable material takes different paths from the source to the mandrel to produce a structure of smaller diameter fibers randomly oriented, larger diameter fibers and/or bundles of fibers circumferentially oriented and elongated voids circumferentially oriented.

Method and apparatus for manufacturing electrostatically spun structure

A tubular fibrous structure having smaller diameter fibers randomly oriented and larger diameter fibers and/or bundles of fibers circumferentially oriented. The structure includes elongated voids also generally circumferentially oriented.

Electrostatically produced structures and methods of manufacturing

An aorto-coronary bypass graft comprising a plate portion and at least one tube portion extending from the plate portion, the opening in the tube portion communicating with a corresponding opening in the plate portion.

Method of manufacturing synthetic vascular grafts

Apparatus for producing a fibrous structure including electrostatically charged mandrels arranged around a delivery assembly for fiberizable material. The delivery assembly includes capillary needles to which fiberizable material is supplied from a reservoir, the needles being arranged on manifolds moved continuously around a loop path on a rail.
