Abstract
Description
Kathetercatheter
Katheter für die Behandlung von Fluiden in Ventrikeln und/oder Subarachnoidalräumen sowie dem Hirngewebe.Catheter for the treatment of fluids in ventricles and/or subarachnoid spaces as well as brain tissue.
In der neurochirurgischen, neurologischen, neonatologischen und pädiatrischen Therapie ist der Einsatz von Kathetern für die Behandlung von Fluiden in Ventrikeln und/oder Subarachnoidalräumen bzw. des Hirngewebes bei einer Vielzahl von Erkrankungen mit Hirndrucksymptomatik durch eine externe Liquordrainage bekannt. Diese bekannten Einmalsysteme sind nicht für eine ständige Überwachung des Liquordruckes über einen Monitor bei gleichzeitiger Drainage ausgelegt.In neurosurgical, neurological, neonatal and pediatric therapy, the use of catheters for the treatment of fluids in the ventricles and/or subarachnoid spaces or brain tissue in a variety of diseases with symptoms of intracranial pressure through external CSF drainage is known. These known single-use systems are not designed for constant monitoring of CSF pressure via a monitor while simultaneously draining.
Für eine ständige Drucküberwachung und Drainage sind Mikrochipkatheter oder fieberoptische Katheter bekannt, deren Anschaffung sehr kostenintensiv ist und die mit einer aufwendigen Messtechnik versehen demzufolge nur bei besonderen Erkrankungen eingesetzt werden.
Die erforderliche und notwendige Messung des intracraniellen Druckes erfolgt mittels eines externen Druckwandlersystemes.Microchip catheters or fever-optical catheters are known for constant pressure monitoring and drainage, but their purchase is very expensive and they are equipped with complex measuring technology and are therefore only used in special diseases.
The required and necessary measurement of intracranial pressure is carried out using an external pressure transducer system.
Bei diesen Kathetern aus dem bekannten Stand der Technik ist es nachteilig, dass eine gleichzeitige Druckmessung und Drainage nicht möglich ist.The disadvantage of these state-of-the-art catheters is that simultaneous pressure measurement and drainage is not possible.
Ein weiterer Nachteil besteht darin, dass bei der Anwendung im Bereich des menschliehen Gehirns der Katheter mittels geeigneter technischer Maßnahmen lokalisierbar sein muss. Dies ist bisher nur mit solchen Kathetern möglich, die durch den Einsatz bestimmter chemischer Stoffe voll konstrastiert sind.A further disadvantage is that when used in the area of the human brain, the catheter must be localizable using suitable technical measures. This has so far only been possible with catheters that are fully contrasted by the use of certain chemical substances.
Die Vollkontrastrierung führt zu einer rauen Oberflächenstruktur der Katheter mit den Nachteilen der Anlagerung von Proteinen, Bakterien und Zellbestandteilen.Full contrast leads to a rough surface structure of the catheters with the disadvantages of the accumulation of proteins, bacteria and cell components.
Weiterhin ist eine optische Kontrolle der Fluiden durch die Vollkontrastierung der Katheter nicht möglich.Furthermore, optical control of the fluids is not possible due to the full contrast of the catheters.
Die Katheter werden derzeit so verwendet, dass diese mittels spezieller und aufwendiger Verbindungselemente den erforderlichen Funktionen Druckmessung und Drainage nacheinander zugeführt werden.The catheters are currently used in such a way that they are supplied with the required functions of pressure measurement and drainage one after the other by means of special and complex connecting elements.
• t•t
Die damit verbundenen Probleme und Schwierigkeiten, insbesondere die Diskonnektionsmöglichkeit mit der Gefahr der Bakterieninfektion des Gehirnes stellt einen schwerwiegenden und nicht akzeptierbaren Nachteil dar. Die medizinisch geforderte kontinuierliche Aufzeichnung des intracraniellen Druckes wird durch die Drainagezyklen unterbrochen.The associated problems and difficulties, in particular the possibility of disconnection with the risk of bacterial infection of the brain, represent a serious and unacceptable disadvantage. The medically required continuous recording of intracranial pressure is interrupted by the drainage cycles.
Die Erfindung hat sich nun die Aufgabe gestellt, die Nachteile des bekannten Standes der Technik zu vermeiden und einen Katheter aufzuzeigen, der einfach handhabbar und wirtschaftlich herstellbar ist und bei dem gleichzeitig mit der Zuführung und dem Abfluss von Fluiden eine Überwachung des intracraniellen Druckes kontinuierlich und jederzeit möglich ist.The invention has now set itself the task of avoiding the disadvantages of the known prior art and of demonstrating a catheter which is easy to handle and economical to manufacture and in which, at the same time as the supply and drainage of fluids, monitoring of the intracranial pressure is possible continuously and at any time.
Es soll weiterhin eine optische Kontrolle der zuzuführenden bzw. abfließenden Fluide möglich sein und die Lage des Katheters jederzeit mit der geeigneten Technik lokalisieren zu können, ohne dass es zu Artefakten oder Auslöschen von Hirnstrukturen auf Grund von Überlagerungen durch das Kathetermaterial kommt.It should also be possible to visually monitor the fluids being supplied or drained and to be able to localize the position of the catheter at any time using the appropriate technology without causing artifacts or obliteration of brain structures due to interference from the catheter material.
Erfindungsgemäß wird dies dadurch gelöst, dass der Katheter aus einem polymeren Werkstoff besteht, wobei dieser wenigstens zwei Lumen aufweist, die miteinander verbunden sind, wobei in jedes Lumen, beginnend am freien Ende des Katheters, wenigstens eine Öffnung eingebracht ist und wobei am freien Ende des Katheters ein Kontrollelement eingebracht ist.According to the invention, this is achieved in that the catheter consists of a polymeric material, wherein it has at least two lumens which are connected to one another, wherein at least one opening is introduced into each lumen, starting at the free end of the catheter, and wherein a control element is introduced at the free end of the catheter.
Weitere vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in the subclaims.
Vorteilhaft wird gesehen, dass der erfindungsgemäße Katheter aus einem transparenten polymeren Werkstoff besteht, durch den jederzeit eine optische Kontrolle der zugeführten bzw der abfließenden Fluide durch das medizinische Personal möglich ist.It is seen as an advantage that the catheter according to the invention consists of a transparent polymer material, through which a visual inspection of the supplied or drained fluids by the medical personnel is possible at any time.
Ein entscheidender Vorteil des erfindungsgemäßen Katheters besteht darin, dass bei der erforderlichen Durchführung neuer Therapieformen bei cerebralen Blutungen die gleichzeitige Liquordrainage und die kontinuierliche Druckmessung erstmals möglich sind.A decisive advantage of the catheter according to the invention is that, when new forms of therapy are required for cerebral hemorrhage, simultaneous cerebrospinal fluid drainage and continuous pressure measurement are possible for the first time.
Ein weiterer Vorteil wird darin gesehen, dass es für den Patienten zu keiner zusätzlichen Traumatisierung des Gehirns kommt, da bei der herkömmlichen Behandlung von Fluiden in den Ventrikeln und/oder Subarachnoidalräumen und/oder des Gehirns immer zwei Trepanationslöcher in der Schädeldecke erforderlich sind, die durch die Verbindung mehrerer Funktionen im erfindungsgemäßen Katheter nicht mehr erforderlich sind.A further advantage is seen in the fact that there is no additional traumatization of the brain for the patient, since the conventional treatment of fluids in the ventricles and/or subarachnoid spaces and/or the brain always requires two trepanation holes in the skull, which are no longer necessary due to the combination of several functions in the catheter according to the invention.
Ein weiterer Vorteil wird darin gesehen, dass durch den erfindungsgemäßen Katheter dessen Positionierung in den durch cerebrale Blutungen befallenen Ventrikeln und/oder Subarachnoidalräumen durch das Kontrollelement sehr schnell und genau möglich ist.A further advantage is seen in the fact that the catheter according to the invention allows its positioning in the ventricles and/or subarachnoid spaces affected by cerebral hemorrhages very quickly and precisely by means of the control element.
Der erfindungsgemäße Katheter hat eine hohe Anwendersicherheit, da durch diesen keine Konnektion auf herkömmliche Katheterverbindungselemente erforderlich ist und damit auch mögliche Leckagen auszuschließen sind.
Aufgrund des geometrisch einfachen Aufbaues und der verwendeten Materialien ist der erfindungsgemäße Katheter kostengünstig herstellbar und trotzdem leicht handhabbar. The catheter according to the invention has a high level of user safety, since it does not require a connection to conventional catheter connecting elements and thus also excludes possible leaks.
Due to the geometrically simple structure and the materials used, the catheter according to the invention can be manufactured cost-effectively and is nevertheless easy to handle.
Im Rahmen der Erfindung liegt auch die Verwendung eines Katheters mit beispielsweise drei Lumen, wobei hier vorteilhafterweise über ein Lumen der Zufluss von Medikamenten in die mit cerebralen Blutungen versehenen Ventrikel und/oder Subarachnoidalräume zugeführt wird, mit dem Ziel, die vorhandenen Hämatome zu verflüssigen, wobei das zweite Lumen dem Abfluss der verflüssigten Hämatome dient und einem dritten Lumen, durch das die kontinuierliche Druckmessung während dieser Behandlung ermöglicht ist.The invention also includes the use of a catheter with, for example, three lumens, wherein the inflow of medication into the ventricles and/or subarachnoid spaces affected by cerebral hemorrhage is advantageously supplied via one lumen with the aim of liquefying the existing hematomas, the second lumen serving to drain the liquefied hematomas and a third lumen through which continuous pressure measurement is possible during this treatment.

Die Erfindung soll nun an einem dieser nicht beschränkenden Ausführungsbeispielen näher beschrieben werden. Es zeigt:The invention will now be described in more detail using one of these non-limiting embodiments. It shows:
Figur 1: Katheter gemäß der Erfindung
5Figure 1: Catheter according to the invention
5
In Figur 1 ist der erfindungsgemäße Katheter (1) dargestellt, der die Lumen (2, 3) aufweist und aus einem transparenten polymeren Werkstoff hergestellt ist.
Am freien Ende (10) des Katheters (1) ist das Kontrollelement (4) eingebracht, welches aus einem im Röntgen- und/oder Computertomograhie- und /oder MRT Magnetresonanztomographieverfahren sichtbaren Material besteht, beispielsweise aus Titan. Dieses Kontrollelement (4) ist in diesem Ausführungsbeispiel unmittelbar an der Spitze des freien Endes (10) des Katheters (1) auf der Längsachse (A) eingebracht und durch die Lumen (2, 3) vollflächig umschlossen.Figure 1 shows the catheter (1) according to the invention, which has the lumens (2, 3) and is made of a transparent polymeric material.
The control element (4) is inserted at the free end (10) of the catheter (1), which consists of a material that is visible in X-ray and/or computer tomography and/or MRI magnetic resonance imaging procedures, for example titanium. In this embodiment, this control element (4) is inserted directly at the tip of the free end (10) of the catheter (1) on the longitudinal axis (A) and is completely enclosed by the lumens (2, 3).
Der Katheter (1) verfügt am freien Ende über in das Lumen (2, 3) eingebrachte Öffnungen (21, 22, 23, 24 und 31, 32, 33, 34, 35), die in diesem Ausführungsbeispiel sowohl diametral gegenüberliegend als auch alternierend gegenüberliegend eingebracht sind.
Der Abstand der Öffnungen (21, 22, 23, 24 und 31, 32, 33, 34, 35) beträgt in diesem Ausführungsbeispiel in etwa das Dreifache ihrer Abmessungen, wobei sowohl der Abstand als auch die Dimensionierung der Öffnungen (21, 22, 23, 24 und 31, 32, 33, 34, 35) vom jeweiligen Anwendungszweck abhängen und entsprechend den Anforderungen an die zu behandelnden Ventrikel bzw. Subarachnoidalräume anpassbar sind. Die Lumen (2, 3) des Katheters (1) sind in diesem Ausführungsbeispiel einstückig miteinander verbunden und aus dem gleichen transparenten polymeren Werkstoff hergestellt.The catheter (1) has openings (21, 22, 23, 24 and 31, 32, 33, 34, 35) at the free end in the lumen (2, 3), which in this embodiment are both diametrically opposite and alternately opposite.
In this embodiment, the distance between the openings (21, 22, 23, 24 and 31, 32, 33, 34, 35) is approximately three times their dimensions, whereby both the distance and the dimensions of the openings (21, 22, 23, 24 and 31, 32, 33, 34, 35) depend on the respective application and can be adapted to the requirements of the ventricles or subarachnoid spaces to be treated. In this embodiment, the lumens (2, 3) of the catheter (1) are connected to one another in one piece and made from the same transparent polymer material.
Es liegt jedoch auch im Rahmen der Erfindung, dass der Katheter (1) Lumen (2, 3) aufweist, die aus unterschiedlichen Werkstoffen hergestellt sind.However, it is also within the scope of the invention that the catheter (1) has lumens (2, 3) made of different materials.
-5--5-
Dies kann beispielsweise ein härteres Material für das Lumen (2) sein, welches stabilisierend bei der Einführung des Katheters (1) in die zu behandelnden Ventrikel und/oder Subarachnoidalräume dient und ein weicheres Material für das Lumen (3), welches sich der Geometrie in den Ventrikeln bzw. Subarachnoidalräumen anpasst.
5This can, for example, be a harder material for the lumen (2), which serves to stabilize the insertion of the catheter (1) into the ventricles and/or subarachnoid spaces to be treated, and a softer material for the lumen (3), which adapts to the geometry in the ventricles or subarachnoid spaces.
5
Der Katheter (1) weist in diesem Ausführungsbeispiel, beginnend ab der Öffnung (31), Markierungselemente (5,5') auf, die beispielsweise in einer metrischen Skalierung aufgebracht sein können und dem medizinischen Personal eine zusätzliche Information beim Einführen des Katheters in die Ventrikel und/oder Subarachnoidalräume liefern.In this embodiment, the catheter (1) has marking elements (5,5') starting from the opening (31), which can be applied, for example, in a metric scale and provide the medical personnel with additional information when inserting the catheter into the ventricles and/or subarachnoid spaces.
Am freien Ende (11) des Katheters (1) ist ein Verbindungselement (6) dargestellt, in welchem die Lumen (2, 3) so fixiert werden, dass sie über die Schläuche (25, 35) zu den Anschlusselementen (26, 27) weiterleitbar sind, an die die entsprechenden Druckmessvorrichtungen bzw. Flüssigkeitszugabeelemente anschließbar sind. Das Verbindungselement (6) verhindert hier ein mögliches Trennen der Lumen (2, 3).At the free end (11) of the catheter (1) there is a connecting element (6) in which the lumens (2, 3) are fixed in such a way that they can be passed on via the tubes (25, 35) to the connecting elements (26, 27) to which the corresponding pressure measuring devices or liquid addition elements can be connected. The connecting element (6) prevents the lumens (2, 3) from becoming separated.
