Abstract: The present invention pertains to medical devices. More specifically, the present application is related to an aspiration catheter for a medical clot removal system and to a clot removal system comprising such an aspiration catheter. An aspiration catheter for a clot removal system has a distal section and a proximal section, wherein, in the distal section, a ratio of an outer diameter (Dd) and an open lumen inner diameter (ID) is in a range between 1.05 and 1.09, and wherein a volume of the aspiration catheter is in a range between 0.2 cubic inches and 0.4 cubic inches.

Abstract: The vessel connecting means or the connector for surgically connecting two vessels together comprises a tubular body having a smaller diameter in the center region than at the ends and has at least two penetrations through which pairs of circular surgical needles are inserted. The connector provides a blood-tight connection of two natural or artificial vessels, including prosthesis connections, a prosthesis with a natural vessel, or even two prostheses. The vessel connection can be made very much faster, more easily, and more reliably with the new mechanical connector than with a conventional circumferential surgical suture.

Abstract: A stent made of a self-expandable or balloon-expandable metal mesh fabric that can be widened to a diameter larger than that of the descending aorta. The stent has a flexible lining of vessel-replacing material, wherein the lining covers it at least partly in longitudinal direction and forms a tubular segment which projects beyond the end of the stent at least at one end and which functions as the vascular prosthesis. Such implantable arrangements (1) make it possible to achieve short surgical times, especially during the treatment of aortic arch aneurysms involving the cephalic arteries.
