Abstract
This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.
Claims11
An endovascular device comprising:
- an expandable stent comprising a proximal end comprising proximal apices and an opposed distal end comprising distal apices with the proximal and distal apices being interconnected by struts therein between,
- the proximal apices having a proximal apical width;
- the distal apices having a distal apical width;
- wherein the proximal apical width of the proximal apices is smaller than the distal apical width of the distal apices;
- and
- wherein a ratio of the distal apical width to the proximal apical width is about 10 or higher.
