Abstract

The invention relates to a device for the removal of foreign bodies and thrombi from body cavities and blood vessels using a guide wire provided with a distal element with said distal element being provided with an orthogonal structure.

Claims (9)

1. A thrombus removing device, comprising a micro-catheter and a first guide wire, the first guide wire being provided with a distal element, a second guide wire having an oblong cage structure at its distal end that is suited to be flatly collapsible under an external strain exerted by the micro-catheter and capable of being transported inside the micro-catheter and unfolded to its full cage structure when said external strain caused by the micro-catheter is omitted, wherein the cage structure comprises an external wire structure reinforced by three or more braces extending longitudinally and is provided with a net structure, and wherein the distal element is provided with a guide inside the cage, a proximal and a distal wire element of the distal element are slidably arranged inside the cage, the guide being a wire of helically wound shape and comprising a radiopaque metal, and wherein the distal element and the cage structure are configured so as to be movable in relation to each other.

2. The device according to claim 1 , wherein the distal element further comprises platinum or a platinum alloy.

3. The device according to claim 1 further comprising a guiding catheter.

4. The device according to claim 1 , further comprising a guiding catheter and the micro-catheter, wherein at least one of the catheters is configured as an aspiration catheter.

5. The device according to claim 1 , wherein the braces are made of a shape-memory material.

6. The device according to claim 5 , wherein the braces consist of nitinol.

7. The device according to claim 1 , characterized in that the helically wound wire consists of platinum or a platinum alloy.

8. The device according to claim 1 , wherein the braces extend in a configuration offset by 180°.

9. The device according to claim 1 , wherein the cage structure has been covered distally with a polymer structure.
