BIOPROTEZA VALVULARA CARDIACA SI PROCEDEU DE REALIZARE

摘要

A cardiac valvular bioprosthesis is made of a biologic material (aortic valva of wild boar, bear or other animal) of a special structure which is applied on metallic support (2) or plastic material by means of connection stratum (3) of knitted textile material and the fixation on the heart is accomplished by means a ring (4) of textile material, plastic or silicone rubber. The support (2) for the bioprosthesis is made of a basis (A) and a superstructure (B). The basis (A) has a circular form with a diameter according to the diameter of the prosthesis which must be replaced and, on the circumference, presents a tube (b) of 1-2 mm, interrupted by some resistance pills (c), of which some in the middle of the flankeys (d) and the others in the middle of the curve between the two flankeys. Further is described a proceeding of achievement of cardiac valvular bioprosthetics.
