Abstract:
An anastomotic device for joining a graft vessel to a target vessel at a connection opening present therein, comprising:an essentially tubular body having a bottom rim to be directed towards the target vessel; an outer flange that is fitted or can be fitted on the outside of the tubular body and can be brought into contact, around the connection opening, with the outside of the wall of the target vessel; and an inner flange, formed on the tubular body, which in a attachment position projects outwards with respect to the tubular body and, overlapping the outer flange around the connection opening, can come into contact with the inside of the wall of the target vessel and which is bendable from an insertion position into said attachment position, wherein, in the insertion position, the projection of the inner flange on the plane spanned by the bottom rim of the tubular body is located essentially on and/or inside said bottom rim, such that the inner flange can be inserted through the connection opening in the target vessel, characterised in that, the inner flange is reversibly bent against a resilient force from the attachment position into the insertion position, which is a pretensioned position, and that the inner flange is fixed in said pretensioned insertion position in a manner such that the fixing can be released in order to cause the inner flange to bend back in the direction of the attachment position under the influence of the pretension.
