Catheter

Kurzbeschreibung

The invention presented comprises a catheter which enables targeted local treatment of aneurysms by reducing the volume of an aneurysm.

Beschreibung/Hintergrund

Vascular diseases such as aneurysms can be externally stapled or surgically removed, depending on their size, type and location, which can cause significant trauma. Another option for treating aneurysms is the endovascular procedure, in which the aneurysm is filled or disconnected from the blood flow. However, filling the aneurysm does not reduce the volume of the vessel outpouching. Thus, the pressure on intact tissue structures is not reduced and therefore associated limitations remain. A possibility to combine the advantages of surgical stapling with endovascular access is endovascular clipping.

Lösung

The presented catheter was developed by an employee of the Otto-von-Guericke-University Magdeburg and allows a targeted local treatment of aneurysms by reducing the volume of an aneurysm. The catheter comprises an outer tube element and an inner tube element, which are arranged coaxially to each other and each have a distal and proximal end. At the tip of the catheter is a flexible element in the form of a ring or loop, which can be expanded or contracted by axial movement of a pulling means to apply a force to the element. As a result, aneurysms can be easily aspirated into the catheter and endovascularly occluded by the flexible element. The flexible element is thereby detached from the traction device and remains in the patient`s body. Due to the arrangement of the flexible element at the catheter tip, new treatment options are created, reducing trauma and increasing the patient`s chances of recovery.
