Abstract: The present invention relates to a medical device (10), preferably a micro robot for application inside a body, preferably for application inside a human body (2). The medical device (10) includes a body part (11) and a tail part (12). A controlling line (13) is attached to the tail part (12). The controlling line (13) has a tensile strength sufficient to pull back the device from a target location and/or control its velocity and column strength not sufficient to push the medical device (10).

Abstract: The invention relates to a medical implant (1) that is adapted to repair or close defect (D), in particular an opening in a ventricular, atrial, or septal wall (W). The medical implant (1) may, in particular, be a patch. It comprises an adhesive composition (6). It further comprises two states, wherein in the first state, the medical implant (1) can be deployed to an implant site while the adhesive composition (6) is inactive. It can be brought into a second state by an activation mechanism. The adhesive composition (6), in the second state, is curable by a curing mechanism.

Abstract: The invention relates to medical implant (1) that is adapted to close a defect (D) or a cavity, preferably a defect in an atrial or septal wall (W) or a left atrial appendage. The implant (1) comprises an occlusion device (6) and has two states. It is adapted to, in a first state, be deployed to a defect site (D), where it can be brought into a second state by an activation mechanism. It is adapted to close said defect (D) in said second state.

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: The invention relates to a positioning device (1) comprising a distal part (8) that is adapted to be delivered through a defect, preferably an opening in a ventricular or atrial septum. It comprises a mechanism to selectively expand the distal part (8), such that before expansion, it can be deployed through said defect, and upon expansion, is mechanically prevented from being retracted through the same defect. Thus, the positioning device (1) is temporarily engaged at the defect site.
