Embodiment Construction

[0054] exist figure 1 , image 3 and Figure 4 In the illustrated embodiment, the woven aortic sinus prosthesis 1 has a portion 2 not close to the heart, which is shaped cylindrically except for a transverse folded portion 3 . The portion 2 that is not close to the heart can enter at its upper end 4 seamlessly or by means of a transverse seam into the aortic arch, which is not shown in the figure. The part 2 of the aortic sinus prosthesis that is not close to the heart enters at its lower end 5 axially and seamlessly into the bulbous part 6 . When viewed in the circumferential direction, the spherical portion 6 can be uniformly ( figure 1 and Figure 4 ) or unevenly ( Figure 5 ) to extend. The spherical part 6 also has a transverse corrugated part 3 . A substantially cylindrical portion 8 close to the heart is also connected axially and seamlessly to the lower end 7 of the spherical portion 6 , said portion 8 being likewise cylindrically shaped except for the transvers...

Abstract

The invention relates to a woven aortic sinus prosthesis (1) having a first substantially cylindrical section (2) not close to the heart, which possibly transitions into an aortic arch, a second section (6) forming a bulb, which is expanded in comparison to the first section with regard to the diameter and which connects to the first section (2), and possibly a third substantially cylindrical section (8) close to the heart, which connects to the bulb section (6).

Description

technical field [0001] The present invention relates to a woven aortic sinus prosthesis. Background technique [0002] Replacement of the aortic region close to the heart, especially the so-called ascending aortic region, is one of the most important specialties in the field of modern cardiac surgery. A variety of vascular prostheses have been developed to achieve the above objectives. These vascular prostheses are usually implanted after removal of the aneurysmatic portion of the ascending aorta, and specifically after removal of the aortic sinus (natural sinus) while maintaining the aortic valve and arterial wall Some cases are implanted. [0003] Early vascular prostheses were straight and homogeneous tubular prostheses. A disadvantage of these types of vascular prostheses is that they do not have an additional structure which in particular can replace the function of the aortic sinus removed during surgery. Therefore, they cannot adequately correspond to the actual a...
