Abstract: The present invention relates to an endograft device (101) for treatment of ruptures (104.9) in one or more inner layers of a blood vessel (104), in particular, an aorta, comprising an anchoring unit (101.1) and a sleeve unit (101.2). The endograft device (101) defines an upstream endograft end (101.3) and a downstream endograft end (101.4), upstream and downstream being defined, in an implanted state of the endograft device (101), in relation to a general natural blood flow defining a blood flow direction within the blood vessel (104). The anchoring unit (101.1) is a collapsible unit located at the upstream endograft end (101.3), wherein the anchoring unit (101.1) is configured to anchor, in the implanted state, the endograft device (101) within the blood vessel (104) by engaging an inner surface of the blood vessel (104) with an expanded anchoring section (101.5). The sleeve unit (101.2) is located downstream of the anchoring unit (101.1), wherein the sleeve unit (101.

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.
