Beschreibung
Zusammenfassung:	There is provided a unique process for the manufacture of a tubular PTFE or PTFE-tissue hybrid medical device is described having at least one luminal surface that is slightly ridged in a spiral configuration designed to rotate, or propagate the rotational flow of blood that is transitioning from an artery or vein into the implanted medical device. The process for the production of PTFE includes specially designed extrusion equipment depicted herein and/or specially designed tissue molding processes to be used in conjunction with the inventions of Pathak et al. and Edwin. La présente invention concerne un procédé unique de fabrication d'un dispositif médical tubulaire en PTFE ou hybride PTFE-tissu, ayant au moins une surface luminale qui est légèrement nervurée dans une configuration en spirale, conçue pour entraîner en rotation, ou propager le flux rotatif de sang passant d'une artère ou d'une veine dans le dispositif médical implanté. Le procédé de production de PTFE comprend les équipements d'extrusion spécialement conçus décrits dans le présent document et/ou des procédés de moulage du tissu spécialement conçus pour être utilisés conjointement aux inventions de Pathak et al. et Edwin.
