Tubular ePTFE materials which are capable of being radially expanded under the influence of a radially outward force applied from the lumen of the ePTFE tubular material to substantially uniformly radially deform the ePTFE material. The ePTFE material is radially expandable to a diameter 700 % its unexpanded diameter under the influence of pressures less than 6 atm while retaining the structural integrity of the ePTFE microstructure. Conservation of the structural integrity of the ePTFE material is determined by conservation of the ePTFE microstructure structural integrity.

L'invention concerne des matériaux tubulaires en PTFE expansible pouvant se développer radialement sous l'influence d'une force radiale centrifuge, exercée depuis la lumière du tube en PTFE expansible, de façon à la déformer radialement, de manière sensiblement uniforme. Le tube en PTFE expansible peut se développer radialement jusqu'à atteindre, sous des pressions de moins de 6 atm, un diamètre de 700 % supérieur à son diamètre avant développement, tout en gardant l'intégrité structurelle de la microstructure du PTFE expansible. Le maintien de l'intégrité structurelle de la matière en PTFE expansible est lié au maintien de l'intégrité structurelle de la microstructure du PTFE expansible.
