Abstract: The invention relates to a catheter device (1) for retrieving a thrombus (T) from a vessel. The catheter device comprises a main body (15) with an internal channel (15?) extending at least through a distal part of the main body (15). An attachment element (4) is attached or attachable to the main body (15) by a flexible line (2). The attachment element (4) further comprises a magnetic element (7) for steering and/or guiding by an external magnetic actuator and is adapted to attach to the thrombus (T) by means of a suction mechanism. The suction mechanism may include a suction hole (8) and/or a suction line (3). The suction mechanism may comprise a suction cup (6). The thrombus (T) is retrievable with the catheter device by exerting a pulling force on the attachment element (4) via the flexible line (2).

Abstract: The invention relates to a device (1) for treatment of a vessel (V) in a patient comprising a filling element (5,7,10,13,14,15,29), a magnetic element (4), a controlling line (2), a release mechanism (3). The release mechanism (3) is adapted to release the magnetic element (4) and/or the filling element (5,7,10,13,14,15,29) such as to be separated from the controlling line (2). The magnetic element (4) is adapted to be guided by an external actuator (M) such as to guide at least the filling element (5,7,10,13,14,15,29) along a vessel path (V). The filling element (5,7,10,13,14,15,29) is adapted to, when placed in the vessel (V) to be treated, reduce the volume of said vessel portion (V). The controlling line (2) is adapted to position the device by being loosened or pulled.

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).

Abstract: The invention is directed to a method of determining properties in a vessel or the heart (V) of a patient. It comprises the steps of placing an element in a vessel or the heart(V) and determining a propulsion force (2) acting on the element. Furthermore, at least one of acceleration (3) and velocity (4) of the element is determined. At least one property of a neighbouring medium of the element is determined based on the propulsion force and at least one of acceleration (3) and velocity (4) of the element.

Abstract: A system (10) for moving an intravascular medical device (85) in a vascular network (V) comprises a magnetic actuator (40), a controlling unit (50) and a controlling line driver (60). The controlling line driver (60) is adapted to hold and/or to release a controlling line (70) attached to the medical device (85) at different speeds. The magnetic actuator is adapted to generate a magnetic field (41) at a predetermined location in order to pull the medical device (85) in a pre-determined direction. The controlling unit (50) is adapted to balance at least three forces applied on the medical device (85) and to operate the magnetic actuator (40) and/or the controlling line driver (60).
