Description
Die Erfindung:The invention:
Die Erfindung beschreibt ein implantierbares Verschlusssystem, mit dem Öffnungen in Organen oder Körperoberflächen einfach und schnell verschlossen werden können, in der Art, das Verschlusssystem aus einem membranbespannten Nitinolschirmchen mit Hakenstrukturen besteht, wobei die Membran hierbei die zu verschliessende Öffnung abdichtet und die Hakenstruktur das Verschlusssystem im Gewebe verankert.The The invention describes an implantable occlusion system with openings in organs or body surfaces easy and can be quickly closed, in kind, the locking system from a membrane-covered Nitinolschirmchen with hook structures consists, wherein the membrane in this case seals the opening to be closed and the hook structure anchors the closure system in the tissue.
Problem:Problem:
Chirurgische Operationen werden oft mittels minimalinvasiver Methoden durchgeführt. Hierbei kann auf eine großflächige Öffnung der Körper- oder Organoberfläche verzichtet werden, indem die gesamte Prozedur durch üblicherweise 3 kleine Einstichöffnungen durchgeführt wird. Der Vorteil liegt hier einer verkürzten Prozedur mit einem deutlich verringerten Infektionsrisiko. Die für die Operation notwendigen Werkzeuge werden durch sogenannte Trokare, Hilfsinstrumente, welche einen Kanal durch die Körper- oder Organoberfläche darstellen, geführt. Nach der eigentlichen Operation sind die Trokare zu entfernen und deren Einstichöffnungen zu verschließen. Je nach Anwendungsort, z. B. bei minimalinvasiven Operationen von Föten im Mutterleib, kann sich das dichte Verschließen der Trokareinstichstellen sehr problematisch darstellen.surgical Surgeries are often performed by minimally invasive methods. This can be on a large-area opening the body or organ surface are omitted, by completing the entire procedure by usually 3 small ones Puncture openings is performed. The advantage here is a shortened procedure with a significantly reduced Risk of infection. The tools necessary for the operation are by so-called trocars, auxiliary instruments, which a Represent channel through the body or organ surface, guided. After the actual operation, the trocars are to remove and close their puncture openings. Depending on the application, z. B. in minimally invasive operations of Fetuses in the womb, can close the tight seal the Trokareinstichstellen pose very problematic.
Wie wird das Problem bisher gelöst:How is the problem solved so far:
Wenn möglich werden Trokareinstichstellen bislang zugenäht. Im besonderen Fall der minimalinvasiven Operation von Föten führt die Einstichstelle durch die Bauchdecke und den Uterus. Zum Verschluss der Einstichstellen werden hier bislang Kollagenpropfen eingesetzt. Hiermit beide Gewebsschichten dicht abzuschließen ist nicht oder schwer möglich, die unabdingbare Folge ist in den allermeisten Fällen der Verlust von Fruchtwasser und somit eine zu früh eingeleitete Geburt des Kindes.If Trocar puncture sites have been sewn up so far. In the special case of minimally invasive surgery of fetuses guides the puncture site through the abdominal wall and uterus. To close the puncture sites here are so far Kollagenpropfen used. Hereby close both tissue layers tightly is not possible or difficult, which is the inevitable consequence in the vast majority of cases the loss of amniotic fluid and thus a premature birth of the child.
Zum Verschluss anderer Öffnungen in Organen, z. B. dem Herzmuskel, haben sich einfach oder doppelt aufgeführte Nitinolschirmchen, sogenannte Occluder, etabliert, wie beispielsweise der sogenannte Amplatzer-Occluder [1]. Bei zahlreichen Indikationen, beispielsweise zum Verschluss der Öffnungen im Uterus, eignen sich derartige Systeme nicht, da eine Dichtwirkung vom Ein- und Zuwachsen des Occluders abhängen. Ist ein sicheres Ein- und Zuwachsen des Occluders nicht sichergestellt, können diese Schirmchen nicht zum Einsatz kommen.To the Closure of other openings in organs, eg. The heart muscle, have singly or doubly listed Nitinolschirmchen, so-called Occluder, established, such as the so-called Amplatzer Occluder [1]. For many indications, for example to close the openings in the uterus, such are suitable Systems not, since a sealing effect of the growth and Occluders depend. Is a safe growth and growth of Occluders not guaranteed, these umbrellas can not for Use come.
Lösungsweg:Solution:
Die Erfindung beschreibt Verschluss-Schirmchen, mit denen Trokareinstichstellen nach minimalinvasiven Eingriffen einfach und schnell verschlossen werden können. Insbesondere bei Schwangeren nach Durchführung minimalinvasiver fetoskopischer Eingriffe an ihren Ungeborenen können die Verschluss-Schirmchen durch Trokare mit einem Innendurchmesser von beispielsweise 4–10 mm implantiert werden. Ziel der Implantation ist die dichte Abdeckung eines oder mehrerer iatrogen erzeugter Defekte, beispielsweise der Fruchtblase. Hierdurch können typische Komplikationen der Fetalchirurgie, wie das postoperative Auftreten von Fruchtwasserleckagen, Blasensprung, vorzeitigen Wehen, Infektion und Frühgeburt reduziert oder in deutlich höhere Schwangerschaftsalter verschoben werden.The Invention describes closure umbrellas with which trocar puncture sites be closed easily and quickly after minimally invasive surgery can. Especially in pregnant women after implementation minimally invasive fetoscopic surgery on her unborn baby the closure screens by trocars with an inside diameter be implanted, for example 4-10 mm. goal of Implantation is the dense coverage of one or more iatrogen generated defects, such as the amniotic sac. This can be typical Complications of fetal surgery, such as postoperative occurrence of amniotic fluid leaks, rupture of membranes, premature labor, infection and premature birth reduced or in significantly higher gestational age be moved.
Konstruktiv wird dieses Ziel mit einem membranbespannten Nitinolschirmchen umgesetzt, welches nach Applikation den Uterus von innen her abdichtet. Die Membran besteht hierbei aus einer fluidisch dichten Polymermembran, welche unmittelbar nach Applizierung des Schirmchens für eine Abdichtung der zu verschließenden Organ- oder Körperöffnung sorgt.constructive this target is reacted with a membrane-covered Nitinolschirmchen, which seals the uterus from the inside after application. The Membrane consists of a fluid-tight polymer membrane, which immediately after application of the screen for a seal of the organ or body opening to be closed provides.
Eine Fixierung im Uterus in vorgespanntem Zustand des Schirmchens wird durch Hakenstrukturen erzielt, welche sich im umliegenden Gewebe, beispielsweise in der Bauchdecke, verankern. Abhängig vom Heilungszustand können die Verschlusssysteme durch membranseitigen Zug entfernt werden.A Fixation in the uterus in pretensioned state of the screen becomes achieved by hook structures which are located in the surrounding tissue, For example, in the abdominal wall, anchor. Depending on Healing state, the closure systems by membrane-side Train to be removed.
Zur Applikation des Uterus-Verschlusses ist ein geeignetes Einführsystem bereitzustellen, welches im Wesentlichen aus einem Einführungsrohr besteht.to Application of the uterine closure is a suitable delivery system to provide, which consists essentially of an insertion tube.
