Definitions

  • Support ring for supporting a biological aortic valve prosthesis
  • the invention relates to a support ring for supporting an aortic valve prosthesis, consisting of two rings running at a constant distance from one another and three struts connecting the rings to one another.
  • Such a support ring is shown in DE 36 08 435 C2, in which the two rings have the same diameter and the two rings each run in one plane.
  • the previously known support ring does not take sufficient account of the anatomical conditions.
  • the invention is based on the object of developing the known support ring in such a way that the anatomical conditions are better taken into account.
  • this object is achieved in that the upper ring has a slightly smaller diameter than the lower ring and the rings form three shafts in a developed view, the struts connecting the rings to one another in the region of the wave crests.
  • the diameter of the upper ring is preferably 1.5 to 2.5 mm less than that of the lower ring, the height of the wave crests and the depth of the wave troughs is preferably between 2 and 6 mm.
  • the struts should be wider than the rings.
  • Titanium is particularly suitable as the material.
  • the support ring should be made from one piece.
  • the support ring consists of two rings 10, 12, each of which runs in a wave shape while maintaining their parallelism.
  • the height of the wave crests and the depth of the wave valleys are each 2 to 6 mm, so that the plane of the vertices of the lower ring 12 and the plane of the vertices of the upper ring 10 are at a distance of 2 to 12 mm from one another to have.
  • the diameter of the upper ring 10 is 1.5 to 2.5 mm smaller than that of the lower ring.
  • the struts In the - preferred - regular arrangement of the struts, they have an angular distance of 120 ° from one another.
  • a biological heart valve preparation is sewn into the support ring as described in DE 39 10 971 Cl and then introduced into the patient's aorta with the support ring.

Abstract

Bague d'appui pour maintenir une prothèse biologique de valvule de l'aorte, constituée de deux bagues disposées à égale distance (10, 12), ainsi que de trois entretoises (14) reliant les bagues entre elles, caractérisée en ce que la bague supérieure a un diamètre légèrement moins grand que la bague inférieure, et que les bagues forment, dans une représentation développée, trois ondulations, les entretoises reliant les bagues entre elles au voisinage des sommets des ondulations.
