Abstract

Ballonkatheter als Instrument zur schonenden Trennung und Entfernung von Gefäßwandverkalkung dadurch gekennzeichnet, dass dieser aus einer fixierenden Kanüle mittig und mehreren Stäben an der Ballonoberfläche besteht, die axial und soweit überstehend angeordnet sind, dass nur die Stäbe die Gefäßwand im erkrankten Bereich dehnen.Balloon catheter as an instrument for the gentle separation and removal of vascular wall calcification, characterized in that it consists of a fixing cannula in the center and several rods on the balloon surface, which are arranged axially and protruding so far that only the rods stretch the vascular wall in the diseased area.

Description

Blutgefäße sind versorgende Schläuche, die sich durch verschiedene Erkrankung, Rauchen und Fehlernährung verändern. Diese Veränderung führen zu Ischämien, Infarkten, Organverlust und im Extremfall zum Tod. Eine Erkrankung der Gefäßwand ist dabei eine der häufigsten Ursache für Schlaganfall und Herzinfarkt. Diese Veränderungen stellen sich meist als Verkalkung, sogenannte Atherosklerose dar. Bislang werden bei fortgeschrittenen Gefäßobliterationen u. a. risikoreiche Methoden wie Bypass-Operation und Ballonierung mit Stenteinlage durchgeführt. Die bekannten Ballonkatheter ( US 2007/0073329 A1 , US 5797935 A und US 6989025 B2 ) sind durch eine Erweiterung der Gefäßeinengungen mittels Ballonisierung und Einlage von Stents und ähnlichem gekennzeichnet. Hierbei werden die Stenosen durch Erweiterung und Offenhaltung behoben.Blood vessels are supplying tubes that change due to various illnesses, smoking and malnutrition. This change leads to ischaemias, heart attacks, organ loss and, in extreme cases, death. A disease of the vessel wall is one of the most common cause of stroke and heart attack. These changes are usually calcification, so-called atherosclerosis. So far, in advanced vascular obliterations, among other things, high-risk methods such as bypass surgery and ballooning with stent insert are performed. The known balloon catheters ( US 2007/0073329 A1 . US 5797935 A and US 6989025 B2 ) are characterized by an expansion of vascular constrictions by means of ballooning and insertion of stents and the like. Here, the stenoses are resolved by expansion and keeping open.

Ziel dieses Projektes ist eine neue Methodik und Technik zur risikoärmeren Behandlung lebensgefährlicher Gefäßerkrankungen anzubieten.The aim of this project is to offer a new methodology and technique for the less risky treatment of life-threatening vascular diseases.

In 1 ist A ein Ballon zu sehen, der durch mit einem Loch oder mehrere Löcher versehenen Tubus B mit Kochsalz auf- und abgepumpt werden kann. E sitzt als Fortsetzung auf Tubus B und verläuft durch den Ballon A. E hat die Aufgabe den erkrankten Bereich der Gefäßwand zu fixieren und besteht aus einem stabilen, verschiebbaren Kunststoffmaterial, das körperverträglich sein sollte. Die Spitze von E ist verborgen und soll beim Einführen das Mannövrieren in Gefäßschlingen und Abzweigung ermöglichen. C und D sind 2 stabile Kunststoffstäbe, die auf Ballon A aufliegen (in 1 wurde aus Einfachheitsgründen nur C und D gezeichnet. Es gibt aber mehr solche Stäbe in der Konstruktion). Nach der Fixierung der erkrankten Gefäßwand G wird die Konstruktion weiter geschoben und der Ballon A vor dem erkranktem Bereich mit Kochsalz aufgepumpt und die Stäbe C und D dehnen das Gefäß aus und lösen Stück für Stück den Plaque von der Gefäßwand. Die Konstruktion wird nach jedem Schritt weitergeschoben. Am Ende ist die Verkalkung durch Stäbe umgegriffen und kann entfernt werden. Bei asymmetrische Gefäßverkalkung kann ein formmodifiziertes E eingesetzt werden.In 1 A is to see a balloon that can be pumped up and down through hole or multi-hole Tubus B with saline. E sits as a continuation on tube B and passes through the balloon A. E has the task to fix the diseased area of the vessel wall and consists of a stable, movable plastic material that should be biocompatible. The tip of E is hidden and should allow maneuvering into vascular loops and branching upon insertion. C and D are 2 stable plastic rods resting on balloon A (in 1 For simplicity's sake, only C and D were drawn. But there are more such bars in construction). After fixation of the diseased vessel wall G, the construction is pushed further and inflated the balloon A before the diseased area with sodium chloride and the rods C and D expand the vessel and solve piece by piece the plaque from the vessel wall. The construction will be moved after each step. At the end of the calcification is encompassed by rods and can be removed. For asymmetric vascular calcification, a shape-modified E can be used.
