VASCULAR PROSTHESIS SYSTEM
First Claim
1. A vascular prosthesis system for inserting into and supporting a blood vessel of a patient, which vascular prosthesis system is convertible from a compressed state to an expanded state, said vascular prosthesis system having the following:
- a stent graft element with a hollow cylindrical body, a first, proximal stent graft element end and a second, distal stent graft element end, the stent graft element having supports extending circumferentially in a meandering formation, and a prosthesis material for forming a circumferentially covered stent graft element, which prosthesis material is fastened to and connects the supports, anda stent element with a hollow cylindrical body, a first, proximal stent element end and a second, distal stent element end, the stent element having a stent support framework, which is free of prosthesis material, for forming an uncovered stent element,whereinthe stent graft element and the stent element are two structurally separate elements of the vascular prosthesis system, and the stent element is dimensioned and designed in such a way that it is insertable with its second, distal stent element end at least partially into the first, proximal stent graft element end and is expansible therein,wherein furthermore the stent element at its first, proximal end, is firmly connected circumferentially to a stent-free prosthesis portion, which prosthesis portion is made solely of prosthesis material,and wherein furthermore the stent graft element and the stent element are connected to each other only by a strip-shaped prosthesis material portion, in such a way that the strip-shaped prosthesis material portion is fixed with a first end on the first, proximal stent graft element end and is fixed with its second end on the first, proximal stent element end in order to form a prosthesis material bridge.

Abstract
The invention relates to a vascular prosthesis system for inserting into and for supporting a blood vessel of a patient. The vascular prosthesis system comprises (i) a stent graft element comprising a prosthesis material, and (ii) a stent element free of prosthesis material. Furthermore, a strip-like prosthesis material segment is provided, by means of which the stent graft element and the stent element are connected to each other, in such a way that the strip-like prosthesis material segment forms a prosthesis material bridge.
