Abstract
Description
Die Erfindung betrifft einen implantierbaren Katheter, bestehend aus einem länglichen, zylinderförmigen Element mit einem axialen Innenraum und mit radial verlaufenden, durchgehenden Öffnungen.The The invention relates to an implantable catheter consisting of an oblong, cylindrical Element having an axial interior and with radially extending, through openings.
Derartige Katheter werden in zahlreichen medizinischen Gebieten verwendet, beispielsweise in der Chirurgie, Urologie, Gastroenterologie, Pulmonologie, Gynäkologie und Kardiologie. Rohrförmige Katheter dienen beispielsweise zum Unterstützen der Flüssigkeitsdrainage aus der Niere durch den Harnleiter, aus der Leber durch die Gallengänge, aus der Bauchspeicheldrüse durch den Bauchspeicheldrüsenkanal, aus der Gallenblase durch den Gallengang und dergleichen.such Catheters are used in many medical fields For example, in surgery, urology, gastroenterology, pulmonology, gynecology and cardiology. Tubular catheters serve, for example, to support the drainage of fluid from the kidney through the ureter, out of the liver through the bile ducts, out of the pancreas through the pancreatic duct, from the gallbladder through the bile duct and the like.
Der Hauptgrund für den Einsatz eines Katheters in einem Flüssigkeitskanal besteht darin, für eine Drainage, also einen ungehinderten Flüssigkeitsdurchgang, zu sorgen, um eine Blockierung zu umgehen, die beispielsweise dadurch entstehen, dass Steine in den Harnleiter ausgeschieden werden, wo sie sich festsetzen. Ähnlich können Steine von der Gallenblase in den Gallengang ausgeschieden werden und sich dort festsetzen. Die Funktion eines implantierten Katheters besteht beispielsweise darin, eine Blockierung des Harnleiters zu überbrücken und eine Urindrainage von der Niere zu der Harnblase über einen Zeitraum von typischerweise einigen Tagen bis zu mehreren Monaten zur Verfügung zu stellen.Of the Main reason for the use of a catheter in a fluid channel is for drainage, So an unhindered fluid passage, to ensure that it bypasses a blockage, for example arise that stones are eliminated in the ureter, where they to commit yourself. Similar can Stones from the gallbladder are excreted into the bile duct and settle there. The function of an implanted catheter For example, it is to bridge a blockage of the ureter and a Urinary drainage from the kidney to the urinary bladder over a period of typically a few days to several months.

Der Erfindung liegt die Aufgabe zugrunde, einen implantierbaren Katheter der eingangs erwähnten Art so zu verändern, dass die erwähnten Reizungen oder Entzündungen vermieden werden, auch wenn es sich um einen Katheter aus hartem Material handelt, und dass die gewünschte Flüssigkeitsdrainage ungehindert funktionieren kann.Of the Invention is based on the object, an implantable catheter the aforementioned To change the way that mentioned Irritation or inflammation be avoided, even if it is a catheter made of hard Material trades, and that the desired liquid drainage unhindered can work.
Diese Aufgabe wird mit den in den Ansprüchen 1 und 2 angegebenen Merkmalen gelöst.These The object is achieved with the features specified in claims 1 and 2 solved.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Further advantageous embodiments of the invention are specified in the subclaims.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass ein einmal implantierter Katheter aus elastischem oder hartem Material lange Zeit ohne Beschwerden im Körper verbleiben kann, weil er keine Reizungen oder Entzündungen hervorruft und weil der gewünschte Flüssigkeitstransport einwandfrei funktioniert.The particular advantages of the invention are that a once implanted catheter made of elastic or hard Material can remain in the body for a long time without discomfort because it causes no irritation or inflammation and because of the desired fluid transport works perfectly.
