Abstract:
An implantable, fully pliable, venous prosthesis comprising:(a) a synthetic, biocompatible, longitudinally seamless, outer tube that is the diameter of the lumen of a diseased, injured, or otherwise nonfunctioning section of human vein, (b) a synthetic, biocompatible, longitudinally seamless, inner tube of essentially the same diameter as the outer tube, (c) a means for securing said inner tube inside said outer tube in a line along the circumference that forms three equivalent and approximately parabolic sections, with the juncture of said inner tube and said outer tube streamlined on surfaces in contact with flowing blood, whereby said parabolic sections are supported at said line along the circumference, and whereby said outer tube is conforming to the natural vein contours and movement, and whereby blood is allowed to flow only in one direction within said prosthesis.
