Abstract
Description
Die Erfindung betrifft eine Vorrichtung für die Steigerung der Perfusion im Herzmuskelgewebe.The invention relates to a device for the increase perfusion in the heart muscle tissue.
Zur Perfusion gehört Blut mit Sauerstoff, Lymphe, Körper- bzw. Organflüssigkeit. Ein hohes Druckgefälle im Organ begünstigt die Perfusion, und wir dürfen annehmen, daß eine perfekte Perfusion zumindest die Heilung von Krankheiten wie Herzmuskelinfarkte mit Verschwielung begünstigt. Das Gefäßsystem des Herzens ist eingeschaltet zwischen dem hohen Druck der aufsteigenden Aorta bzw. Aortenwurzel und der Großen Herzvene, die als Vene mit "verbrauchtem Blut" nur einen sehr geringen Blutdruck besitzt. Durch den über die Cava cranialis in die Große Herzvene vorgeschobenen Unterdrucksaugkatheter wird das Druckgefälle zur Aorta bzw, dem Blut in den Herzkranzschlagadern zur physikalischen Therapie vergrößert, die Perfusion im Herzmuskelgewebe gesteigert. Das Einbringen eines Katheters in den rechten Herzvorhof sowie in die darin einmündende Große Herzvene dürfte dem nicht gar zu jungen Herzchirurgen keine Schwierigkeiten machen. Ist der Heilerfolg gegeben, erkennt ist der Unterdruckkatheter wieder herauszuziehen.Perfusion includes blood with oxygen, lymph, Body- or organ fluid. A high pressure drop favored in the organ perfusion and we may assume that a perfect perfusion at least the healing of diseases like myocardial infarction favored with calluses. The vascular system of the heart is switched between the high pressure of the ascending Aorta or aortic root and the great cardiac vein, which acts as a vein with "used up Blood "only one has very low blood pressure. Through the cranial cava into the Size The cardiac vein advanced negative pressure suction catheter becomes the pressure drop Aorta or, the blood in the coronary arteries to the physical Therapy increases that Perfusion in the heart muscle tissue increased. The insertion of a catheter in the right auricle as well as in the great cardiac vein that flows into it might who do not cause any problems even to young cardiac surgeons. If the healing is successful, the negative pressure catheter is recognized pull it out.

Die Aufgabe der Erfindung wird bei gattungsgemäßer Einrichtung durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Die weitere Ausgestaltung der Erfindung ist den Unteransprüchen und der Zeichnung bzw.

The Another embodiment of the invention is the subclaims and can be seen from the drawing or illustrations.
Mit der Erfindung erzielten Vorteile:
Für den Menschen
bzw. den Patienten handelt es sich um ein vergleichsweise schonendes
Verfahren, Lediglich auf der rechten Herzseite kommt per Katheter
physikalisch begrenzt Unterdruck besonders in der imparen Großen Herzvene
zur Anwendung über
Stunden , ggf. Tage. Der Unterdruckkatheter kann auch zugleich als
Ballonkatheter ausgebildet sein, dadurch kann der vor dem Katheter
gelegene Venenraum in Steigerung der Perfusionswirkung im Herzen
oder in anderen Organen, auch bei erkranktem Bein/Fuß begrenzt/
abgeschlossen werden. Die Geräte
außen am
Körper
bestehen vor allem aus einer geeigneten Druckpumpe, Druckmesser
wie Quecksilbermanometer und eine Wulffsche Flasche , die in
Während der letzten Jahrzehnte sind Herzkatheter, auch Ballonkatheter besonders zur Aufdehnung stenosierter Stämme der Herzkranschlagadern über die Aorta ins arterille Herzgefäßsystem vorgeschoben worden. Solche Gefässaufdehnungen fördern auch die Perfusion im Herzmuskelgewebe, aber Einengungen und Durchblutungsstörungen in kleineren Kranzarterienästen können in dieser Weise nur schwer behandelt werden. Die Steigerung der Perfusion von der venösen Seite, wie jetzt von mir dargelegt, wirkt generell, bedingt könnte man auch von dreidinensional sprechen. Das eröffnet neue Möglichkeiten der Behandlung von Herzerkrankungen wie auch Myocarditis und aus meiner Sicht, ist das Verfahren mit Unterdruck von der venösen Seite auch schonender.While Cardiac catheters, including balloon catheters, have been special in recent decades for the expansion of stenosed strains the cardiac veins over the aorta into the arterial cardiovascular system been advanced. Such vasodilation promote also perfusion in the heart muscle tissue, but constrictions and circulatory disorders in smaller coronary artery branches can difficult to treat in this way. The increase in Perfusion from the venous Side, as I have now explained, works in general, one could do it conditionally also speak of three-dimensional. This opens up new opportunities the treatment of heart disease as well as myocarditis and from in my view, the procedure with negative pressure is from the venous side too friendly.
