Abstract
An endoprosthesis to be implanted in vessels damaged in a way as to be detrimental to the flow of the biological fluids they convey, intended for the treatment of aneurysms in areas of a vessel in the vicinity of a bifurcation, such as, for example, an aneurysm of the abdominal aorta.
Claims7
A modular endoprosthesis comprising:
- (i) a body A and a body B, constructed with a self-expanding monofilament of NiTi wire with a PET fabric or ePTFE graft;
- the bodies being formed by proximal, intermediate and distal regions;
- (ii) the said bodies A and B have a portion of greater diameter that divides, in a bifurcating portion, in at least two legs with one being significantly shorter than the other;
- (iii) the said proximal region of said body A comprises a structure of resistant and flexible material wherein a free end comprises a stent without graft having a configuration appropriate for attachment to the vessel wherein the remainder of the said body A comprising the said metal structure is stitched to the graft in at least two points;
- (iv) the said intermediate region of the said bodies A and B comprises a structure of resistant and flexible material stitched to the graft;
- (v) the said distal region of the said bodies A and B have laser cuts Z stents without graft comprising a configuration appropriate for attachment to the vessel walls, and
- (vi) the said bodies A and B are coupled in a manner that the said body B remains positioned within the said body A forming a sealed connection impeding leakage of the blood from inside the endoprosthesis to the aneurysm and the disconnection of the modules bodies A and B.
