Device for the removal of thrombi from blood vessels

摘要

The invention relates to a device for the removal of foreign objects and thrombi from body cavities and blood vessels (12) using at least one guide wire (6, 7) provided with a distal element (2), said distal element (2) being provided with fibers (3) projecting radially outward and the device being provided with a cage (1) or tubular structure (16) which is suitable to be flatly collapsible under the external strain exerted by a micro-catheter (13) and transported inside the micro-catheter (13) and unfolds to its full cage (1) or tubular (16) structure when said external strain caused by the micro-catheter (13) is omitted, with said distal element (2) and the cage (1) or tubular (16) structure being designed so as to be longitudinally movable in relation to each other and the cage (1) or tubular structure (16) having an opening at the distal end through which the distal element (2) can be introduced into said cage (1) or tubular (16) structure. With the help of the inventive device thrombi (5) can be safely eliminated from blood vessels (12) in a simple manner.
