The invention relates to an intervertebral disc prosthesis for the total replacement of a natural intervertebral disc within the lumbar and cervical spine, comprising articulating sliding partners, where the upper sliding partner has means for a firm assembly to an upper vertebral body and the lower sliding partner has means for a firm assembly to a lower vertebral body and at least one sliding surface that is between two sliding partners. According to the invention, functional two- and three part designs are planned and both prostheses have in common, that only a dorsoventral- and rotation movement is possible as a result of laterolaterally aimed, transversally arched, ventrally curved cylindrical convexity(ies) and corresponding concavity(ies), however without an inclination of the sliding partners in a lateral direction. In a further design, the cylindrical articulation surfaces are un-curved, enabling a motion of the sliding partners in only a ventrodorsal direction. According to the invention, the intervertebral disc prostheses are suited for an implantation from lateral and ventrolateral, particularly in revision surgeries.

A bifurcated or straight intravascular folded tubular member is deliverable percutaneously or by small cutdown to the site of a vascular lesion. Its inserted state has a smaller nondeployed diameter and a shorter nondeployed length. The intravascular tubular member has a folded tubular section that is unfolded following insertion into the blood vessel. The length of the intravascular folded tubular member is sized in situ to the length of the vessel lesion without error associated with diagnostic estimation of lesion length. The folded tubular member is self-expandable or balloon-expandable to a larger deployed diameter following delivery to the lesion site. An attachment anchor can be positioned at the inlet or outlet ends of the intravascular folded tubular member to prevent leakage between the tubular member and the native vessel lumen and to prevent migration of the tubular member. The attachment anchor has a short axial length to provide a more focal line of attachment to the vessel wall. Such attachment is valuable in attaching to a short aortic neck in the treatment of abdominal aortic aneurysm. The attachment anchor can have barbs which are held in a protected conformation during insertion of the tubular member and are released upon deployment of the attachment anchor. The intravascular tubular member can be formed of woven multifilament polymeric strands with metallic strands interwoven along with them. Double weaving is incorporated to prevent leakage at crossover points.
