Patent ID: 8043551

Claim:
A process for the production of an aortic or mitral cardiac valve prosthesis, comprising: shaping flaps ( 2 ) by pressing an edge zone of a textile membrane against a counter-form by applying suction of a first fluid through said counter-form so that the flaps are formed with shapes corresponding to a structure of said counter-form; and thermofixing the flaps obtained in said shaping step by drawing a second fluid through the textile membrane into the counter-form, the second fluid being sufficiently hot to thermofix the textile membrane, wherein said thermofixing step follows said shaping step, and wherein the textile membrane is of the type formed by an assembly mode selected from the group consisting of i) woven, ii) non-woven in the form of assembled fibers, and iii) non-woven obtained by autofibrillation of a membrane by drawing and knitting.
