Abstract

Bereich einer insbesondere mittels Ballonkatheter aufweitbaren Arterienverengung einsetzbar ist, wobei die Wandung der Gefäßstütze dehnbar ist und in radialer Richtung dadurch aufweitbar ist, dass sie zumindest bereichweise aus bleibend verformbaren Metallstegen gebildet ist, dadurch gekennzeichnet, dass bei Überschreiten einer definierten radialen Ausdehnung, die Metallstege infolge einer eingebauten Sollbruchstelle sich öffnen.The area of an arterial constriction, which can be expanded in particular by means of a balloon catheter, can be used, the wall of the vascular support being expandable and being expandable in the radial direction in that it is formed, at least in regions, from permanently deformable metal webs, characterized in that when a defined radial expansion is exceeded, the metal webs result open a built-in predetermined breaking point.

Description

Die Erfindung:The invention:

Die Erfindung betrifft eine implantierbare Gefäßstütze, die als Stützhülse im Bereich einer insbesondere mittels Ballonkatheter aufweitbaren Arterienverengung einsetzbar ist, wobei die Wandung der Gefäßstütze dehnbar ist und in radialer Richtung dadurch aufweitbar ist, dass sie zumindest bereichweise aus bleibend verformbaren Metallstegen gebildet ist und bei Überschreiten einer gewissen radialen Ausdehnung die Metallstege infolge einer eingebauten Sollbruchstelle sich öffnen. Gefäßstützen dieser Art werden besonders bei der Behandlung der Pulmonalstenose bei Kindern benötigt.The invention relates to an implantable vascular support which can be used as a support sleeve in the region of an arterial constriction that can be widened, in particular, by means of a balloon catheter. The wall of the vascular support is expandable and can be widened in the radial direction by being formed at least partially from permanently deformable metal webs and when it exceeds one certain radial expansion of the metal webs due to a built-in breaking point open. Vascular supports of this type are particularly needed in the treatment of pulmonary stenosis in children.

Wie wurde das Problem bisher gelöst:How has the problem been solved so far:

Die Möglichkeiten des Aufweitens in radialer Richtung sind je nach Modell beschränkt, so dass es vor allem in solchen Fällen, in denen größere Aufweitungsmöglichkeiten in mehreren Schritten erwünscht sind, wie dies bei Kindern mit einer Pulmonalstenose der Fall ist, Schwierigkeiten auftreten können. Vermeidet man eine sofortige Operation und implantiert diesen Säuglingen einen normalen Stent, so bildet dieser nach ein paar Jahren wachsender Gefäße selbst eine Stenose.The possibilities of expansion in the radial direction are limited depending on the model, so that it can be difficult, especially in those cases where larger expansion options are desired in several steps, as is the case with children with pulmonary stenosis. By avoiding immediate surgery and implanting a normal stent into these infants, it forms a stenosis itself after a few years of growing vessels.

Gefäßstützen in dieser Art sind in vielfältiger Form bereits bekannt.Vascular supports in this type are already known in many forms.

Eine derartige Gefäßstütze ist aus DE 101 05 160 B4 bekannt, die durch einen absorbierbaren Faden zusammen gehalten wird, aber keine Sollbruchstelle enthält. Eine Gefäßstütze ähnlicher Art ist aus DE 10 2004 027 108 B4 bekannt, die in zwei Schritten aufweitbar ist, aber auch hier keine Sollbruchstelle enthält.Such a vascular support is off DE 101 05 160 B4 known, which is held together by an absorbable thread, but does not contain a predetermined breaking point. A vascular support of a similar nature is made DE 10 2004 027 108 B4 known, which is expandable in two steps, but also contains no predetermined breaking point.

Eine weitere ähnliche Gefäßstütze mit resorbierbarem Material ist aus DE 101 03 000 A1 bekannt.Another similar vascular support with absorbable material is made DE 101 03 000 A1 known.

Aus DE 10 2008 045 039 A1 ist eine Gefäßstütze mit einer Solbruchstelle bekannt, die aber durch ihre spiralförmige Konstruktion bei gleichzeitiger radialer Pulsation der Gefäße, ausgelöst durch den Herzschlag, in ihrer radialen Aufweitung inkonstante Sollbrucheigenschaften aufweist, sodass auf eine Weiterentwicklung zunächst verzichtet worden ist.Out DE 10 2008 045 039 A1 is a vascular support with a Solbruchstelle known, but by their spiral construction with simultaneous radial pulsation of the vessels, triggered by the heartbeat, has in their radial expansion inconstant predetermined breaking properties, so that has been dispensed with a first development.

Eine weitere Gefäßstütze ist aus US 5 591 223 bekannt. Hier erfolgt eine erweiterte radiale Öffnung durch ein unkontrolliertes Reißen und nicht durch eine definierte Sollbruchstelle.Another vascular support is off U.S. 5,591,223 known. Here is an extended radial opening by an uncontrolled tearing and not by a defined breaking point.

Lösungsweg/Beschreibung der Erfindung:Solution / description of the invention:

Es besteht daher die Aufgabe eine Gefäßstütze der eingangs definierter Art zu schaffen, die eine große radiale Dehnbarkeit erlaubt und bei einem bestimmten Umfang sich radial öffnet.It is therefore an object to provide a vascular support of the type defined, which allows a large radial extensibility and radially opens at a certain extent.

Zur Lösung dieser Aufgabe ist die eingangs definierte Gefäßstütze dadurch gekennzeichnet, dass die Metallstege in ihrer Anordnung eine sehr große radiale Aufweitung erlauben und miteinander durch Ösen verbunden sind, wobei eine Öse jeweils in ihrem Umfang einen Schlitz aufweist, so dass bei Überdehnung sich die Öse öffnet und die Verbindungen gelöst werden.To solve this problem, the above-defined vascular support is characterized in that the metal webs allow in their arrangement a very large radial expansion and are connected to each other by eyelets, with an eyelet each having a slot in its circumference, so that when overstretching the eyelet opens and the connections are solved.

Welche Vorteile haben die technischen Merkmale?What are the advantages of the technical features?

Der wichtigste Vorteil dieser Erfindung liegt darin, dass mit Hilfe einer Gefäßstütze mit einer Sollbruchstelle eine spätere Operation bei Kindern mit einer angeborenen Pulmonalstenose, Aortenisthmusstenose und andere Indikationen des Gefäßssystems beim Kleinkind vermieden werden kann.The most important advantage of this invention is that with the help of a vascular support with a predetermined breaking point, a subsequent operation in children with congenital pulmonary stenosis, aortic coarctation and other indications of the vascular system in the infant can be avoided.

Beschreibung der Abbildungen:Description of the pictures:

1 zeigt eine beispielhafte Darstellung der implantierbaren Gefäßstütze (1). Die Stege (2) der Gefäßstütze sind so geformt, dass sie eine möglichst große radiale Expansion ermöglichen. In den Abschnitten, die die radiale Expansion bestimmen werden jeweils zwei Stege (3) und (4) durch die beiden Ösen (6) und (7) zusammen gehalten. 1 shows an exemplary representation of the implantable vascular support ( 1 ). The bridges ( 2 ) of the vascular support are shaped so that they allow the largest possible radial expansion. In each of the sections which determine the radial expansion two webs ( 3 ) and ( 4 ) through the two eyelets ( 6 ) and ( 7 ) held together.

2 zeigt in einer beispielhaften Darstellung einen Teil der implantierbaren Gefäßstütze kurz vor dem endgültigen Zusammenbau der Ösen. Man erkennt, dass eine Öse (6) vollkommen geschlossen ist, während die andere Öse (7) geschlitzt ist. Die Abmessungen und die Materialeigenschaften der Ösen bestimmen im Wesentlichen die gewünschte Sollbruchstelle. 2 shows in an exemplary representation a portion of the implantable vascular support just before the final assembly of the eyelets. It can be seen that an eyelet ( 6 ) is completely closed while the other eyelet ( 7 ) is slotted. The dimensions and the material properties of the eyelets essentially determine the desired breaking point.

3 zeigt in einer beispielhaften Darstellung einen Teil der implantierbaren Gefäßstütze im montierten Zustand der beiden Ösen (6) und (7). Die Sollbruchstelle wird durch die geschlitzte Öse (7) gebildet und hängt von dem Material und der Art und Größe des Schlitzes ab. 3 shows an exemplary representation of a part of the implantable vascular support in the assembled state of the two eyelets ( 6 ) and ( 7 ). The breaking point is determined by the slotted eyelet ( 7 ) and depends on the material and the type and size of the slot.
