Abstract:
An intravascular tubular member for use in treatment of an injured artery that conveys blood flow from a proximal arterial region proximal to the injured artery to one or more distal arterial vessels and is introduced in an nondeployed state with a smaller nondeployed diameter through an artery that supplies blood to or receives blood from the injured artery and expands upon deployment to a larger deployed diameter and is implanted in a fully deployed state, said intravascular tubular member comprising;A. a proximal tubular section with an open free inlet end to provide passage for blood flow into said intravascular tubular member from the proximal arterial region;B. one or more distal tubular sections, each of said one or more distal tubular sections having an open free outlet end to provide passage of blood flow out of said intravascular tubular member to one or more distal arterial vessels;C. an intravascular tubular member wall extending between said inlet end of said proximal tubular section and said outlet end of each of said one or more distal tubular sections;D. one or more folded tubular sections, each of said one or more folded tubular sections having an upstream end and a downstream end, said upstream end of each of said one or more folded tubular sections being joined to said proximal tubular section and said downstream end of each of said one or more folded tubular sections being joined to one of said one or more distal tubular sections, each of said one or more folded tubular sections having said intravascular tubular member wall folded back and forth upon itself forming an inner wall, a center wall, and an outer wall;whereby said intravascular tubular member extends in an axial length from said inlet end to said outlet end during the deployment from the nondeployed state to the fully deployed state as said center wall decreases in length.
