Abstract: An extra-vascular cuff-type implant with inflatable membrane(s) is provided to constrict the vein to serve as a venous valve. The inflatable bladder is inflated by hydraulic pressure from a fluid reservoir that is disposed parallel to the vein to mimic normal physiology.

Abstract: An implantable endograft device which may be characterized as an endograft assembly that is effectively anchored with respect to the weakened blood vessel by filling the aneurysmal sac to preclude further enlargement thereof and to anchor the endograft with respect to the aneurysm. In this way, migration of the endograft is inhibited and exposure of the aneurysmal sac to endoleak circulatory pressures is limited thereby minimizing the risk of vessel wall rupture.

Abstract: Devices and methods are described to facilitate the coupling of two wires introduced into the vascular system at two different points in the body. The coupling enables the formation of a continuous wire entering the body at one point and exiting at another remote point. The device consists of two wires "A" and "B" with a magnetic element attached to one end of each wire. The coupling is formed by the forces of attraction between the magnetic elements. Wire "A" is introduced at one point in the vascular system, for example, in the femoral artery. Wire "B" is then introduced at another point in the vascular system, for example, the axiliary artery. The wires are advanced towards each other under fluoroscopic guidance. The magnetic tips couple once the two wires near each other. The coupled wires are then withdrawn together from either of the two access sites. Once the magnetic coupling exits the body, a single wire is left traversing the vascular system.
