Abstract

A mitral valve reconstruction ring consisting of two curved hoops (10, 12) and two connecting struts (14, 16). The struts (14, 16) are made out of a material which enables them to be bent at right angles, thereby reducing their length.

Description

Mitralklappenrekonstruktionsring Mitral valve reconstruction ring
Die Erfindung betrifft einen Mitralklappenrekonstrukti- onsring.The invention relates to a mitral valve reconstruction ring.
Mitralklappenrekonstruktionsringe finden in der Herzchirurgie bei Vorliegen einer Mitralinsuffizienz oder einer Mitralklappeninsuffizienz Verwendung.Mitral valve reconstruction rings are used in cardiac surgery in the presence of mitral regurgitation or mitral regurgitation.
Bei der Mitralinsuffizienz mit normaler Segelbeweglichkeit ist der dilatierte Annulus die Ursache einer unzureichenden Koaptationsflache der Segel, die einen dauerhaften Verschluß während der gesamten Systole verhindert. Bei der Mitralklappeninsuffizienz dagegen liegt eine überschießende Segelbeweglichkeit vor, die auf einer Elongation der Sehnenfäden oder deren Ruptur beruht.In mitral regurgitation with normal sail mobility, the dilated annulus is the cause of an insufficient coaptation area of the sails, which prevents permanent closure during the entire systole. With mitral valve insufficiency, on the other hand, there is excessive sailing mobility, which is due to an elongation of the tendon threads or their rupture.
Bisher werden starre und flexible Mitralklappenrekon- struktionsringe (Carpentier bzw. Duranring) verwendet, die durch eine Reduzierung des Rings der Mitralklappe zu deren erhöhten Schlußfähigkeit führen. Dabei stellt sich das Problem, das wegen der begrenzten Anzahl verfügbarer Ringe eine genaue Anpassung an die jeweiligen anatomischen Verhältnisse nicht möglich ist. Bei dem Carpentierring stellt sich weiter das Problem einer unzureichenden Neigungsfähigkeit. Der Erfindung liegt daher die Aufgabe zugrunde, einen Mitralklappenrekonstruktionsring zu schaffen, der intraoperativ an die jeweiligen räumlichen Verhältnisse angepaßt werden kann.So far, rigid and flexible mitral valve reconstruction rings (Carpentier or Duran ring) have been used, which, by reducing the ring of the mitral valve, lead to increased closing capacity. This poses the problem that, due to the limited number of rings available, an exact adaptation to the respective anatomical conditions is not possible. The Carpentierring still has the problem of insufficient inclination. The invention is therefore based on the object of providing a mitral valve reconstruction ring which can be adapted intraoperatively to the respective spatial conditions.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Ausbildung mit zwei gekrümmten Bügeln und zwei diese miteinander verbindenden Streben, wobei die Streben aus einem Material bestehen, das ein eine Verkürzung der Streben bewirkendes Kröpfen erlaubt.According to the invention, this object is achieved by a design with two curved brackets and two struts connecting them to one another, the struts being made of a material which allows the struts to be shortened to shorten them.
Das Material der Strebenist dabei so gewählt, daß die durch das Kröpfen bewirkte Verkürzung der Streben dauerhaft ist, die Strebenselbst aber biegsam sind. Die Streben können auch gelenkig an die Bügel angesetzt sein, um ein Verkippen relativ zu dem Bügel zu ermöglichen.The material of the struts is chosen so that the shortening of the struts caused by the cranking is permanent, but the struts themselves are flexible. The struts can also be attached in an articulated manner to the brackets in order to enable them to tilt relative to the bracket.
Bei einem bevorzugten Ausführungsbeispiel ist der eine Bügel stärker als der andere Bügel gekrümmt.In a preferred embodiment, one bracket is curved more than the other bracket.
Besonders bevorzugt ist eine Ausführungsform, bei der sich die Streben winklig zueinander zwischen den Bügeln erstrecken.An embodiment is particularly preferred in which the struts extend at an angle to one another between the brackets.
Die Erfindung wird anhand einer Zeichnung erläutert. Dabei zeigt:The invention is explained with reference to a drawing. It shows:
Fig. 1 den Rekonstruktionsring vor dessen Implantation,1 shows the reconstruction ring before its implantation,
Fig. 2 die insuffiziente Mitralklappe, undFig. 2, the insufficient mitral valve, and
Fig. 3 den in die insuffiziente Mitralklappe implantierten und an die jeweiligen Verhält- nisse durch Kröpfen der Strebenimplantierten Rekonstruktionsring.3 the implanted in the inadequate mitral valve and to the respective conditions nisse by cranking the strut-implanted reconstruction ring.
Der in Fig. 1 gezeigte Mitralklappenrekonstruktionsring besteht aus zwei gekrümmten Bügeln 10, 12 und zwei diese miteinander verbindenden Streben 14, 16. Dabei ist der eine Bügel 10 stärker als der andere Bügel 12 gekrümmt, die Streben 14, 16 verlaufen bei der dargestellten Ausbildung nicht parallel sondern bilden zueinander einen Winkel.The mitral valve reconstruction ring shown in Fig. 1 consists of two curved brackets 10, 12 and two struts 14, 16 connecting them together. One bracket 10 is more curved than the other bracket 12, the struts 14, 16 do not extend in the embodiment shown parallel but form an angle to each other.
Der Bügel ist mit einem Stoff überzogen, der ein Annähen des Mitralklappenrekonstruktionsrings an das Ostium der Mitralklappe ermöglicht.The bracket is covered with a fabric that allows the mitral valve reconstruction ring to be sewn onto the ostium of the mitral valve.
Um eine Anpassung an die anatomischen Verhältnisse der in Fig. 2 gezeigten insuffizienten Mitralklappe zu bewirken, werden die Streben 14, 16, wie in Fig. 3 gezeigt, unter Verwendung einer geeigneten Zange gekröpft, wodurch der Abstand zwischen den Bügeln 10, 12 verkürzt wird. Da die Tiefe der in Fig. 3 erkennbaren Kröpfung der Streben das Ausmaß der Verkürzung des Ab- stands zwischen den beiden Bügeln 10, 12 bestimmt, kann intraoperativ eine genaue Anpassung an die jeweiligen Verhältnisse erfolgen.In order to adapt to the anatomical conditions of the insufficient mitral valve shown in FIG. 2, the struts 14, 16, as shown in FIG. 3, are cranked using suitable pliers, as a result of which the distance between the brackets 10, 12 is shortened . Since the depth of the cranking of the struts which can be seen in FIG. 3 determines the extent of the shortening of the distance between the two brackets 10, 12, an intraoperative adaptation to the respective conditions can take place.
Durch die weiter vorgeschlagene gelenkige Ausbildung der Streben - entweder durch deren gelenkiges Ansetzen an die Bügel 10, 12 oder aber durch eine flexible Ausgestaltung im Bereich der Verbindung mit den Bügeln 10, 12 - wird die gewünschte Fähigkeit zu einer der Bewegung des Annulus folgenden Neigung des Mitralklappenre- konstruktionsrings ermöglicht. Due to the further proposed articulated design of the struts - either by their articulated attachment to the brackets 10, 12 or by a flexible design in the area of the connection to the brackets 10, 12 - the desired ability to an inclination of the annulus following the movement Mitral valve reconstruction ring enabled.
