Abstract
The disclosure relates to a prosthetic device and method for repairing a damaged blood vessel comprising a mat of fibers adjacent the bore of a tube having a disposition substantially parallel to the inner surface of the tube, the mat having a thickness of 0.5 mm to 5 mm.
Claims9
A prosthetic device comprising a tube of vascular diameter said tube comprising an electrostatically spun mat of fibres of diameter 0.1 to 25 microns of a biologically acceptable polymeric material which is selected from the group consisting of polyurethane, polyamide or polyacrylonitrile, and fibres adjacent the bore of the tube having a disposition substantially parallel to the inner surface of the tube, said mat having a thickness of 0.5 mm to 5 mm.
A method of repairing a damaged blood vessel which comprises replacing at least a part of the damaged blood vessel with a prosthetic device comprising an electrostatically spun mat of fibres of diameter 0.1 to 25 microns of a biologically acceptable polymeric material which is selected from the group consisting of polyurethane, polyamide or polyacrylonitrile, and fibres adjacent the bore of the tube having a disposition substantially parallel to the inner surface of the tube, said mat having a thickness of 0.5 mm to 5 mm.
