Abstract

A heart valve prosthesis for replacement of the aortic valve or pulmonary valve comprises a plastic or metal supporting ring (10), three commissure elements and three vela formed from a biological heart valve preparation. The aortic walls of the vela arranged in the supporting ring (10) are stitched, together with the supporting ring (10) and its commissure wall, to the edges of the commissure elements. The commissure elements are formed by strips (12) of felt which stand proud on the supporting ring with their axes parallel and which can be fastened to the walls of the patient's aorta.

Description

Die Erfindung betrifft eine Herzklappenprothese zum Er satz der Aortenklappe oder Pulmonalklappe nach dem Oberbegriff des Anspruchs 1, wie sie aus der DE 83 27 414 U1 vorbe kannt ist. The invention relates to a heart valve prosthesis for aortic valve or pulmonary valve He set according to the preamble of claim 1 as vorbe from DE 83 27 414 U1 is known.

Zum Stand der Technik wird weiter auf die DE 35 41 478 A1, die DE 23 55 959 B2 und DE 36 08 435 C2 hingewie sen. is further made to DE 35 41 478 A1, DE 23 55 959 B2 and DE 36 08 435 C2 hingewie sen to the prior art.

Bei der eingangs genannten Herzklappenprothese sind die Segel des biologischen Herzklappenpräparats an einen wellenförmig ausgebildeten Kunststoffträger angesetzt. In the above-mentioned heart valve prosthesis the leaflets of the biological heart valve preparation are attached to a shaft-shaped plastic support. Der Ort, an dem die Kommissuren der Klappensegel folgt daher nicht der Weitung bzw. der Verengung der Aorta radial. The place where the commissures of the valve leaflets, therefore, does not follow the widening or narrowing of the aorta radially.

Der Erfindung liegt damit die Aufgabe zugrunde, eine Herzklappenprothese der eingangs genannten Art zu schaffen, bei der der Ort, an dem die Kommissuren der Klappensegel verankert sind, sich bei der Weitung bzw. Verengung der Aorta den jeweiligen Druckverhältnissen entsprechend radial bewegen kann. The invention is thus based on the object to provide a heart valve prosthesis of the type mentioned, in which the place where the commissures of the valve leaflets are anchored, can move in the widening or narrowing of the aorta to the respective pressure ratios corresponding radial.

Erfindungsgemäß wird diese Aufgabe durch die im kenn zeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. According to the invention this object is achieved indicated by the drawing in the characterizing part of claim 1. Die Unteransprüche geben vorteilhafte Ausge staltungen der Erfindung an. The sub-claims specify advantageous refinements of the invention Starting at.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. The invention is explained below with reference to a drawing. Dabei zeigt Here shows

Fig. 1 eine perspektivische Darstellung einer sol chen Herzklappenprothese, und Fig. 1 is a perspective view of a sol chen heart valve prosthesis, and

Fig. 2 eine Mittelschnittdarstellung durch eine solche Herzklappenprothese, wobei links ei ner der die Kommissurenelemente bildenden Filzstreifen geschnitten erkennbar ist. Fig. 2 is a central sectional view through such a prosthetic heart valve wherein the left ei ner of the Kommissurenelemente forming felt strip is visible cut.

Die Herzklappenprothese besteht aus einem Stützring 10 mit über den Umfang im wesentlichen gleichbleibender Höhe. The prosthetic heart valve consisting of a support ring 10 having over the circumference a substantially uniform height. Außen um den Stützring herum ist ein Nahtring 16 angeordnet. Around the outside of the support ring is disposed around a suture ring sixteenth

Auf dem Stützring 10 stehen im wesentlichen achsenpar allel ausgerichtete Filzstreifen 12 auf, die mit dem Stützring 10 nicht starr, sondern frei aufstehend verbunden sind. On the support ring 10 allele aligned felt strips 12 are in substantially achsenpar which are connected not rigidly, but free standing up with the support ring 10th

In den Stützring 10 ist ein biologisches Herzklappen präparat - vorzugsweise vom Schwein gewonnen - an deren Aortenwandung 14′ unterhalb und oberhalb der Veranke rung x an den Stützring angenäht, während die Kommissuren 14′′ des biologischen Herzklappenpräparats an den nach giebigen Filzstreifen 12 angenäht sind. Into the support ring 10, a biological heart valve is preparation - preferably obtained from pigs - at whose Aortenwandung 14 'above and below the anchoring tion x to the support ring sewn, while the commissures 14' 'of the biological heart valve preparation are sewn to the after giebigen felt strips 12th

Bei der Implantation der hier vorgeschlagenen Herzklap penprothese wird der fest mit dem Stützring 10 verbun dene Nahtring 16 an die Aortenwandung des Patienten herznah angenäht. Penprothese in the implantation of the proposed Herzklap dene the suture ring fixedly verbun with the support ring 10 is sutured close to the heart of the patient Aortenwandung sixteenth Die freien, von dem Stützring 10 weg weisenden Enden der Filzstreifen 12 werden an die Aor tenwandung des Patienten angeheftet. The free, facing away from the support ring 10 ends of the felt strips 12 are on the Aor the patient tenwandung attached.

Aufgrund der Nachgiebigkeit der die Kommissurenelemente bildenden Filzstreifen 12 verhält sich die Herzklappen prothese nach der Erfindung etwa wie die natürliche menschliche Herzklappe: Der Ort, an dem die Kommissuren der Klappensegel verankert sind, bewegt sich bei der Weitung bzw. Verengung der Aorta radial den jeweiligen Druckverhältnissen entsprechend, was zur zuverlässigen Funktion der Klappensegel beiträgt. Due to the resilience of the Kommissurenelemente forming felt strips 12, the heart valve behaves prosthesis according to the invention is about as the natural human heart valve: The location where the commissures of the valve leaflets are anchored, moves in the widening or narrowing of the aorta radially to the respective pressure conditions accordingly, contributing to the reliable operation of the valve leaflets. Der erreichbare Strömungsquerschnitt ist größer, da bei einer Weitung der Aorta aufgrund des Ausstoßdrucks sich die Veranke rungspunkte der Kommissuren entsprechend nach außen be wegen. The achievable flow area is greater, since in a dilatation of the aorta due to the ejection pressure, the anchoring points of the commissures approximately corresponding to the outside due to be. Es wird so - wie bei der natürlichen Klappe - ein divergenter Fluß bewirkt, da, anders als bei dem Stand der Technik - keine starren Kommissurelemente vorhanden sind. It is so - causes a divergent flow because, unlike the prior art - - as the natural valve no rigid Kommissurelemente are available. Die sich bei dem Stand der Technik hin ter den Kommissurelementen bildenden Toträume werden vermieden. The down ter the Kommissurelementen forming in the prior art dead spaces are avoided.
