SUTURING MEANS FOR CONNECTING A TUBULAR VASCULAR PROSTHESIS TO A BLOOD VESSEL IN THE BODY IN ADDITION TO BRANCH MEANS, A VASCULAR PROSTHESIS, A DEVICE FOR INSERTING AND SUTURING A VASCULAR PROSTHESIS IN THE BODY, AND A VASCULAR PROSTHESIS SYSTEM

摘要

Suturing means and branch means, a vascular prosthesis, a device and a vascular prosthesis system. Suturing means for connecting a vascular prosthesis (40) to a blood vessel (50) comprise an internal, substantially annular body (10) intended to be received in the blood vessel (50) in addition to an external annular body (20) intended to lie clampingly on an outer wall of the blood vessel (50) at least practically at the location of the internal annular body (10). At least one of the two annular bodies (10, 20) is provided with suturing members (12) which grip in the vessel wall so as to effect an adequate fixation of at least the internal annular body (10). The invention also provides a device for use with such suturing means and further relates to a vascular prosthesis which is provided on at least one of its outer ends with at least a part of such suturing means. Different embodiments of such prostheses together form a modular vascular prosthesis system. A side vessel of thus supported blood vessel can be preserved using branch means according to the invention.
