Vessel implant for the treatment of an aneurysm
First Claim
1. A vessel implant for the treatment of an aneurysm, comprising an elongate body having an inlet opening, an outlet opening, and a passage tapering from the inlet opening to the outlet opening, the passage connecting the inlet opening to the outlet opening in a direction of the unidirectional flow of blood through the blood vessel for the blood flowing through the blood vessel, the passage being bounded in the peripheral direction by a blood-impermeable wall, characterized in that the inlet opening has a larger cross-sectional area than the outlet opening and is larger than the outlet opening,wherein the body is provided with blood-permeable fixing means for the end of the body at the outlet opening side, said fixing means being designed for contact with the vessel wall of the blood vessel, said fixing means being designed to hold the body spaced apart from the vessel wall of the blood vessel in the region of the outlet opening, and said fixing means having a radial component projecting outwardly from the body.

Abstract
A vessel implant for the treatment of an aneurysm, i.e. a dilatation of the cross-sectional area of a blood vessel, may include an elongate body having an inlet opening, an outlet opening, and a passage connecting the inlet opening to the outlet opening for the blood flowing through the blood vessel. The passage may be bounded in the peripheral direction by a blood-impermeable wall and the inlet opening may have a larger cross-sectional area than the outlet opening. The body may be provided with blood-permeable fixing means for the end of the body at the outlet opening side. The fixing means may be designed for contact with the vessel wall of the blood vessel. The fixing means may be designed to hold the body spaced apart from the vessel wall of the blood vessel in the region of the outlet opening.

12. A vessel implant for the treatment of an aneurysm, comprising:
-
an elongate body having an inlet opening, an outlet opening, and a passage connecting the inlet opening to the outlet opening for the unidirectional flow of blood through the blood vessel from the inlet opening to the outlet opening, the passage being bounded in the peripheral direction by a blood-impermeable wall, characterized in that the inlet opening has a larger cross-sectional area than the outlet opening and is larger than the outlet opening, and the passage tapers from the inlet opening to the outlet opening; and a blood-permeable fixing section disposed at the end of the body at the outlet opening side sized for contact with the vessel wall of the blood vessel and having a radial component projecting outwardly from the body in more than one polar direction to hold the body spaced apart from the vessel wall of the blood vessel in the region of the outlet opening.
