| abstract |
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. |
