Definitions
- Arrangement for a closure device which can be minimally invasively implanted into the upper or lower vena cava of a human body and a minimally invasively implantable tricuspid valve prosthesis
- the invention relates to an arrangement for a minimally invasively implantable closure device in the upper or lower vena cava of a human body and a mi nimally invasive implantable tricuspid valve prosthesis.
- a minimally invasively implantable mitral or tricuspid valve prosthesis is known from document EP 3 231 393 A1.
- the valve prosthesis is firmly connected to a self-expanding, wide-mesh stent, the shape of which is adapted to a three-dimensionally measured geometry of a patient's left or right atrium and, after implantation, rests against the inner wall of the atrium.
- the object of the invention is to provide an arrangement for a closure device which can be minimally invasively implanted into the upper or lower vena cava of a human body, and a minimally invasively implantable tricuspid valve prosthesis which can be securely located at the site of the implantation and which enables safe opening and closing ,
- an arrangement is created for a closure device which can be minimally invasively implanted into the upper or lower vena cava of a human body, comprising: a valve device in which the closure elements, each of which extends flatly over an element surface, and between a closed position in which the Closure elements jointly close a valve opening, and an opening position can be stored in which a flow is released through the valve opening, an anchoring device which has and is equipped with a self-expandable anchoring, anchor the valve device in the area of the upper or lower vena cava adjacent to the vein opening to the right atrium of the heart; and a flexible sealing collar.
- a minimally invasively implantable tricuspid valve prosthesis is created with such an arrangement.
- the proposed closure device can be securely fixed at the implantation site with the aid of the anchoring device.
- the valve device with the closure elements ensures reliable opening and closing in order to prevent or allow the flow.
- Adjacent closure elements can overlap at least in the closed position in edge-side sections.
- the valve device can be designed as a one-way valve.
- closure elements can be arranged corresponding to a closing surface of a conical peripheral surface in the closed position.
- closure elements can be arranged in the closed position to form a closure surface arranged transversely to a flow direction.
- closure elements can be displaced apart from one another by means of lifting in the flow direction for moving from the closed position into the open position.
- the closure elements can be displaceable between the closed position and the open position by pivoting.
- the closure elements can be pivotable about a pivot axis, which are arranged in the area of a plane spanned by the flexible sealing collar or adjacent thereto.
- the pivot axis can be formed crossing the valve opening.
- Part or all of the closure elements can be connected at least in pairs by means of retaining elements.
- Part or all of the closure elements can be designed as rigid closure elements.
- the anchoring device can have at least one of the following anchoring sections: a first anchoring section which is covered with pericardium or a synthetic membrane plastic material, and a second anchoring section which is free of pericardium and the synthetic membrane plastic material.
- the self-expandable anchor can have at least one anchor from the following group: self-expandable spiral element and self-expandable stent.
- Part or all of the closure elements can consist of a biological material.
- Pericardium for example, can be used as biological material.
- closure elements can consist of a non-biological material.
- Plastic for example, is a usable non-biological material.
- FIG. 1 shows a schematic representation of a device implanted in a vein.
- FIG. 2 shows a schematic illustration of elements of the closure device from FIG. 1;
- Fig. 3 is a schematic perspective view of elements of a closure device in another embodiment
- FIG. 4 shows a schematic illustration of a further closure device which is implanted in the region of a vein
- FIG. 5 shows a schematic illustration of another closure device
- Fig. 6 is a schematic representation of closure elements of a further closure device
- FIG. 7 shows a schematic illustration of a closure device with a lifting cover
- Fig. 8 is a schematic representation of a closure device in a vein with a
- Lifting hopper 9 shows a schematic illustration of another valve device.
- Fig. 10 is a schematic representation of a further valve device.
- Fig. 1 shows a schematic representation of a minimally invasively implantable Ver closure device 1 in the area of a vein 2.
- the closure device 1 With the closure device 1, the flow in the vein 2 can be opened and closed, with a flow only in the in Fig. 1 by arrow A shown flow direction is enabled.
- the closure device 1 closes in the opposite direction and does not allow backflow.
- a section of a vena cava 3, a section of a hepatic vein 4 and a section of the right atrium of the heart 5 are shown.
- the closure device 1 has a valve device 6, an anchoring device 7 and a flexible sealing ring 8, which is formed all around.
- the anchoring device 7 is configured as a self-expanding anchoring which has a spiral 7a.
- the valve device 6 is designed with closure elements 9 which are displaceable and arranged or stretched around a central mast 10. With the Befest onlysele elements 9 sails are formed, which are arranged lamella-like and laterally overlapping, as can be seen in more detail in FIG. 2. In order to enable a flow, the closure elements 9 tilt or pivot (cf. position with dashed lines in FIG. 2), so that a passage 20 is made possible between adjacent closure elements.
- FIG. 3 shows a schematic illustration of elements of a further embodiment of the closure device 1.
- the closure elements 9 open when they are flowed in from below, so that the flow space 20 is released.
- the closure elements 9 are hemmed by means of a seam 31.
- Fig. 4 shows a schematic representation of another embodiment of the Sperreinrich device 1, which is implanted minimally invasively.
- the valve device 6 is formed with the Befest Trentsele elements 9, which have two flaps 40, 41, which are each pivotable about a pivot axis 42.
- the anchoring device 7 is formed with a stent 43, on which barbs 44 are provided, in order to support the anchoring.
- the closure elements 9 can also pivot towards one another in order to open the valve device 6.
- Fig. 5 shows a schematic representation of elements of an embodiment of the closure device 1, in which the closure elements 9 of the valve device 6 have a single pivotable flap 50.
- the closure element 9 is sewn into a nitinol ring 51.
- Fig. 6 shows schematic representations of a further embodiment, in which the closure elements 9 of the closure device 1 are formed with the aid of lifting disks 60 which rise when the flow flows from below in order to release the flow space 20 between adjacent closure elements. With a view from above, adjacent locking elements overlap on the edge.
- Fig. 7 shows a schematic representation of another embodiment of the closure device, in which the closure element is formed by means of a lifting cover 70 which rises when the flow flows from below and releases a flow space 20.
- the embodiment of the closure device in FIG. 8 is formed with comparable functionality, in which the lifting cover 60 is formed with a pear shape.
- closure elements 9 lie in the closed state within the flexible sealing ring 8 in a comparably overlapping petals.
- closure elements 9 pivot open and release the flow area between adjacent closure elements.
- valve device 6 of the closure device 1 is formed with a hose 100, which forms a closure element 9 and expands when it is subjected to the flow, and then contracts again to close the opening.
