Description
Die Erfindung betrifft einen insbesondere für die Aortenklappenanuloplastie geeigneten Anuloplastierring mit einem den Anuloplastiering umgebenden Textilüberzug.The invention relates to a Anuloplastierring suitable for the Aortenklappenanuloplastie in particular with a fabric covering surrounding the Anuloplastiering.
Anuloplastieringe werden für die intravasale und extravasale Implantation zur Wiederherstellung pathologisch veränderter Herzklappen verwendet. Durch Vernähen dieser Prothesen mit dem Herzgewebe kann man einer insuffizienten Herzklappe ihre funktionell richtige Ringstruktur wiedergeben, sodass die Herzklappensegel bzw. Herzklappentaschen wieder zu einem exakten Schluss zusammengeführt werden.Annuloplasty rings are used for intravascular and extravascular implantation to restore pathologically altered heart valves. By suturing these prostheses with the heart tissue, one can reproduce a functionally correct ring structure for an insufficient heart valve, so that the heart valve sails or heart valve pockets are brought together again to an exact conclusion.
Anuloplastieringe sind in
Ein Problem bekannter Anuloplastieringe, insbesondere bei Anuloplastieringen für die Aortenklappenanuloplastie, ist, dass die Ringe direkt unterhalb der Klappe eingebracht werden müssen und im Falle einer Aortenklappe die Klappentaschen während der Diastole, d. h. wenn diese voll entfaltet unter Druck sind, den oberen Rand des Anuloplastierings berühren und damit grundsätzlich – mit fatalen Folgen – verletzt werden können.A problem with known annuloplasty rings, particularly in the case of annuloplasty rings for aortic valve annuloplasty, is that the rings must be inserted directly below the valve and, in the case of an aortic valve, the flap pockets during diastole, i. H. when fully deployed under pressure, touch the upper edge of the annuloplasty ring and thus, in principle - with fatal consequences - can be injured.
Aufgabe der Erfindung ist es daher, einen Anuloplastiering, insbesondere einen für die Aortenklappenanuloplastie geeigneten Anuloplastring zu schaffen, der die Gefahr von Verletzungen der Klappensegel bzw. -taschen verringert.The object of the invention is therefore to provide a Anuloplastiering, in particular a suitable for Aortenklappenanuloplastie Anuloplastring, which reduces the risk of injury to the valve leaflets or bags.
Die Aufgabe wird durch den Anuloplastiering mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.The object is achieved by the Anuloplastiering with the features of claim 1. The subclaims reflect advantageous embodiments of the invention.
Grundgedanke der Erfindung ist es, den bei Anuloplastieringen bekannten Textilüberzug derart auszugestalten, dass dieser einen sich im Wesentlichen vertikal aus der Ringebene erstreckenden Abschnitt aufweist, der einen Nahtsaum ausbildet.The basic idea of the invention is to design the textile cover known in the case of annuloplasty articles in such a way that it has a section which extends substantially vertically out of the plane of the ring and forms a seam.
Durch diesen (Naht-)Saum wird zum einen ein vorteilhafter Abstand des Anuloplastierings zur Herzklappenbasis erzwungen und bei im Querschnitt bevorzugt kegelförmiger Ausbildung des Saums vermieden, dass die Herzklappensegel oder -taschen mit dem Anuloplastiering nach der Erfindung in Berührung kommen.This (seam) seam on the one hand enforces an advantageous distance between the annuloplasty ring and the heart valve base and, with the conical shape of the hem in a preferred cross-section, prevents the heart valve leaflets or pockets from coming into contact with the annuloplasty ring according to the invention.
Zum anderen dient der Saum als Nahtring zur Befestigung des Anuloplastierings am Herzgewebe, sodass die Befestigung des Anuloplastierings erleichtert wird.On the other hand, the seam serves as a sewing ring for attaching the Anuloplastierings the heart tissue, so that the attachment of Anuloplastierings is facilitated.
Neben der im Querschnitt kegelförmigen Ausbildung des Nahtsaums sind auch andere Formen, beispielsweise oval oder rechteckig, denkbar, wobei darauf geachtet werden muss, dass der Nahtsaum in situ nicht mit der Herzklappe in Berührung kommen kann.In addition to the conical cross-sectional design of the seam seam other shapes, such as oval or rectangular, conceivable, care must be taken that the seam in situ can not come into contact with the heart valve.
Der Anuloplastiering kann aus jedem geeigneten Material, beispielsweise Metall oder Kunststoff, hergestellt sein. Der textile Überzug besteht bevorzugt aus Polyethylenterephthalat (PET; Dacron®). The annuloplasty ring may be made of any suitable material, for example, metal or plastic. The textile coating preferably consists of polyethylene terephthalate (PET, Dacron® ).
Die Erfindung wird anhand von in den beiliegenden Zeichnungen dargestellten besonders bevorzugt ausgebildeten Ausführungsbeispielen eines Aortenklappenanuloplastierings näher erläutert, wobei die Erfindung auch bei für andere Herzklappen geeigneten Anuloplastieringen angewendet werden kann. Es zeigen:The invention will be explained in more detail with reference to exemplary embodiments of an aortic valve annuloplasty ring shown in the accompanying drawings, wherein the invention can also be applied to annuloplasty rings suitable for other heart valves. Show it:
Zusätzlich kann eine weitere Spitze vorgesehen sein, wobei die Spitzen der dreieckigen Struktur zwischen dem rechts koronartragenden Sinus und dem nicht koronartragenden Sinus bzw. dem rechts koronartragenden Sinus und dem links koronartragenden Sinus angepasst sind.In addition, another tip may be provided, with the tips of the triangular structure fitted between the right coronary sinus and the non-coronary sinus, the right coronary sinus, and the left coronary sinus.
Im Übrigen weist der Anuloplastiering
Die sich aus der Ringebene erstreckenden Abschnitte sind annähernd der Anatomie zwischen dem rechten koronartragenden Sinus und dem nicht koronartragenden Sinus bzw. zwischen dem rechts koronartragenden Sinus und dem links koronartragenden Sinus nachempfunden und haben vorteilhafterweise eine zum Mittelpunkt des gedachten, von den Abschnitten gebildeten Dreiecks konvexe Konfiguration. Dieses bedeutet, dass sich die Abschnitte leicht in Richtung der Ringebene (konvex) gebogen erstrecken (nicht dargestellt).The sections extending from the plane of the ring are approximately modeled on the anatomy between the right coronary sinus and the non-coronary sinus or between the right coronary sinus and the left coronary sinus and advantageously have a convex configuration centered on the imaginary triangle formed by the segments , This means that the sections extend slightly curved in the direction of the ring plane (convex) (not shown).
Die Spitzen können derart ausgebildet sein, dass nur die Ringoberkante aus der Ringebene geführt ist während die Ringunterkante auf derselben Höhe wie die Ringunterkante verbleibt. Es entsteht also ein flächig verfülltes Dreieck, sodass der Anuloplastiering
