Abstract

The support ring proposed consists of two rings (10, 12) held a constant distance apart by three connecting struts (14) and is characterized by the fact that the upper ring has a slightly smaller diameter than the lower ring and, represented as rolled out, the rings form three waves, the connecting struts being located near the crests of the waves.

Description

Stützring zum Stützen einer biologischen Aortenklappenprothese Support ring for supporting a biological aortic valve prosthesis
Die Erfindung betrifft einen Stützring zum Stützen ei¬ ner Aortenklappenprothese, bestehend aus zwei mit gleichbleibendem Abstand voneinander verlaufenden Rin¬ gen und drei die Ringe miteinander verbindenden Stre¬ ben.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.
In der DE 36 08 435 C2 wird ein derartiger Stützring gezeigt, bei dem die beiden Ringe einen gleichen Durch¬ messer haben und die beiden Ringe in jeweils einer Ebe¬ ne verlaufen.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.
Der vorbekannte Stützring berücksichtigt die anatomi¬ schen Verhältnisse nicht ausreichend.The previously known support ring does not take sufficient account of the anatomical conditions.
Der Erfindung liegt die Aufgabe zugrunde, den vorbe¬ kannten Stützring derart weiterzubilden, daß die anato¬ mischen Verhältnisse besser berücksichtigt werden.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.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der obere Ring einen geringfügig kleineren Durchmesser als der untere Ring hat und die Ringe in einer abge¬ wickelten Darstellung drei Wellen ausbilden, wobei die Streben die Ringe im Bereich der Wellenberge miteinan¬ der verbinden.According to the invention, 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.
Der Durchmesser des oberen Rings beträgt dabei vorzugs¬ weise 1,5 bis 2,5 mm weniger als der des unteren Rings, die Höhe der Wellenberge und die Tiefe der Wellentäler beträgt vorzugsweise zwischen 2 und 6 mm.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.
Die Streben sollen breiter als die Ringe sein.The struts should be wider than the rings.
Als Material kommt insbesondere Titan in Betracht. Zur Vermeidung von Schweißverbindungen oder dgl. soll der Stützring aus einem Stück gefertigt sein.Titanium is particularly suitable as the material. In order to avoid welded connections or the like, the support ring should be made from one piece.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt die einzige Figur den Stützring in perspektivischer Ansicht.The invention is explained below with reference to a drawing. The only figure shows the support ring in a perspective view.
Der Stützring besteht aus zwei Ringen 10, 12, die unter Wahrung ihrer Parallelität jeweils wellenförmig verlau¬ fen. Die Höhe der Wellenberge und die Tiefe der Wellen¬ täler beträgt dabei jeweils 2 bis 6 mm, so daß die Ebe¬ ne der Scheitelpunkte des unteren Rings 12 und die Ebe¬ ne der Scheitelpunkte des oberen Rings 10 einen Abstand von 2 bis 12 mm voneinander haben.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.
Der Durchmesser des oberen Rings 10 ist 1,5 bis 2,5 mm geringer als der des unteren Rings.The diameter of the upper ring 10 is 1.5 to 2.5 mm smaller than that of the lower ring.
Bei der - bevorzugten - regelmäßigen Anordnung der Streben haben diesen einen Winkelabstand von 120° von¬ einander.In the - preferred - regular arrangement of the struts, they have an angular distance of 120 ° from one another.
Zur Implantation wird ein biologischen Herzklappenprä¬ parat in den Stützring wie in der DE 39 10 971 Cl be¬ schrieben eingenäht und dann mit dem Stützring in die Aorta des Patienten eingebracht. For implantation, 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.
