Abstract
The invention is directed to a medical device (1) for retrieving a thrombus (2) from a vessel (3). The medical device (1) comprises an attachment element (4) arranged at a distal end (5) of the medical device (1). The attachment element (4) is adapted to attach to a proximal face (6) of the thrombus such that the thrombus (2) is retrievable by exerting a pulling force on the attachment element (4).

1-24. (canceled)
A medical device for retrieving a thrombus from a vessel, comprising an attachment element, arranged at a distal end of the medical device,
- wherein the attachment element is adapted to attach to a proximal face of the thrombus such that the thrombus is retrievable by exerting a pulling force on the attachment element.
A method of producing a medical device, comprising the steps of
- providing a flexible line with a magnetic part and an attachment element attached thereto;
- coating at least a part of the attachment element with a temporary layer;
- coating at least a part of the medical device;
- removing the temporary layer.
A method of retrieving a thrombus from a vessel with a medical device, comprising the steps of
- introducing a distal end of the medical device in a vessel, the distal end comprising an attachment element
- navigating the medical device to a target location;
- optionally, activating an activation mechanism such that the attachment element is transformed from a deactivated state to an activated state where it is attachable to the thrombus;
- attaching the attachment element to the thrombus on a proximal side of the thrombus;
- optionally, stretching the thrombus to reduce the diameter of the thrombus in a cross-section perpendicular to a longitudinal axis of the vessel;
- removing the thrombus from the target site by pulling on said thrombus.
