Stützring zum Stützen einer HerzklappenprotheseSupport ring for supporting a heart valve prosthesis
Die Erfindung betrifft einen Stützring zum Stützen einer Herzklappenprothese zum Ersatz der Aortenklappe oder der Pulmonalklappe aus Kunststoff oder Metall in der Form von zwei im wesentlichen in gleichbleibendem Abstand zueinander verlaufenden Ringen, die durch Streben miteinander verbunden sind.The invention relates to a support ring for supporting a heart valve prosthesis for replacing the aortic valve or the pulmonary valve made of plastic or metal in the form of two rings which are essentially at a constant distance from one another and are connected to one another by struts.
Der Stand der Technik wird in der DE 36 08 435 C2 beschrieben. Dort ist bereits ein Stützring, dort Gerippe 4 genannt, beschrieben worden. Eine Darstellung ist dort in Fig. 3 zu finden.The state of the art is described in DE 36 08 435 C2. A support ring, called frame 4, has already been described there. A representation can be found in Fig. 3.
Ein Stützring der dort beschriebenen Art hat den Nachteil, daß er aufgrund seiner geraden Ringe nicht optimal an die vorgegebenen Verhältnisse im Körpers, sowie an biologische Herzklappenpräparate angepaßt ist.A support ring of the type described there has the disadvantage that, due to its straight rings, it is not optimally adapted to the given conditions in the body or to biological heart valve preparations.

Aufgabe der Erfindung war es daher, den vorbekannten Stützring derart weiterzubilden, daß er optimal an die Verhältnisse des menschlichen Körpers angepaßt ist und sich besser dazu eignet, biologische Herzklappenpräparate zu implantieren.The object of the invention was therefore to further develop the previously known support ring in such a way that it is optimally adapted to the conditions of the human body and is better suited to implanting biological heart valve preparations.
Erfindungsgemäß wird dies dadurch erreicht, daß einer der Ringe einen geringfügig kleineren Durchmesser besitzt, und daß die Ringe zwischen den Streben, ihren Abstand wahrend, Wölbungen aus der Ebene ihrer Erstreckung besitzen, wobei alle Wölbungen in die Richtung hin weisen, die vom kleineren zum größeren Ring hin weist.According to the invention, this is achieved in that one of the rings has a slightly smaller diameter and that the rings between the struts, while maintaining their distance, have curvatures from the plane of their extension, with all curvatures pointing in the direction from the smaller to the larger ring.
Eine bevorzugte Ausgestaltung weist drei Streben auf, die die Ringe verbinden.A preferred embodiment has three struts connecting the rings.
Es ist vorteilhaft, diese Streben mit einem wesentlich größeren Querschnitt zu versehen.It is advantageous to provide these struts with a much larger cross-section.
Weiter wird empfohlen, für die Ringe und Streben das gleiche Material zu verwenden. Als Material wird Titan empfohlen.It is also recommended to use the same material for the rings and struts. Titanium is recommended as the material.
Besonders vorteilhaft ist es dabei, den Stützring aus einem Stück zu fertigen.It is particularly advantageous to manufacture the support ring from one piece.
Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert. Dabei zeigt :The invention is explained in more detail below with reference to a drawing.
Fig. 1 den Stützring in perspektivischer Ansicht vonFig. 1 the support ring in perspective view of
schräg oben unddiagonally above and

In beiden Figuren ist deutlich zu erkennen, daß der Ring 12 einen etwas größeren Durchmesser als der parallelverlaufende Ring 10 besitzt, und daß drei Streben 14 die Ringe 10 und 12 verbinden.In both figures it can be clearly seen that the ring 12 has a slightly larger diameter than the parallel ring 10 and that three struts 14 connect the rings 10 and 12.
In Fig. 1 ist zusätzlich zu sehen, daß die die Ringe 10, 12 verbindenden Streben 14 wesentlich breiter als die Ringe 10 und 12 ausgeführt sind.In Fig. 1 it can also be seen that the struts 14 connecting the rings 10, 12 are considerably wider than the rings 10 and 12.
In Fig. 2 ist dagegen besser zu erkennen, wie die Ringe 10 und 12 zwischen den Streben 14, ihre Parallelität wahrend, Wölbungen aus der Ebene ihrer Erstreckung besitzen. Es ist auch zu erkennen, daß die hier jeweils drei Wölbungen alle in die gleiche Richtung weisen, nämlich nach unten, in die Richtung vom kleineren Ring 10 zum größeren Ring 12 hin.In Fig. 2, however, it is easier to see how the rings 10 and 12 between the struts 14, while remaining parallel, have curvatures from the plane of their extension. It can also be seen that the three curvatures here all point in the same direction, namely downwards, in the direction from the smaller ring 10 to the larger ring 12.
Aus Gründen der Stabilität und Bruchfestigkeit wird empfohlen, das gleiche Material für die Ringe 10, 12 und die Streben 14 zu verwenden, und, daß der gesamte Stützring nur aus einem Stück gefertigt wird. Damit werden Probleme beim Schweißen vermieden. Als Material wird Titan vorgeschlagen, da es sehr steif ist und auch den weiteren Vorteil sehr großer chemischer Resistenz und guter Biokompatibilität besitzt.For reasons of stability and fracture resistance, it is recommended to use the same material for the rings 10, 12 and the struts 14, and that the entire support ring is made from a single piece. This avoids problems with welding. Titanium is suggested as the material because it is very rigid and also has the additional advantage of being very chemically resistant and having good biocompatibility.
Zur Implantation wird ein Herzklappenpräparat in den Stützring nach der in der DE 39 10 971 Cl beschriebenen Art eingenäht und dann mit dem Stützring dem Patienten implantiert.For implantation, a heart valve preparation is sewn into the support ring in the manner described in DE 39 10 971 Cl and then implanted into the patient with the support ring.
