Abstract:
An endoluminal endoprosthesis device comprising:a first element deployable from a closed, non-deployed position for installation purposes to a deployed, working position and having an upstream end and a downstream end, said first element comprising a first segment having first and second end openings and sized for filling a cross-section of a blood vessel in which said first element is to be incorporated when said first element is in said deployed, working position, said first element further comprising a second segment connected to one of said first and second end openings of said first segment and forming at least two independent trunks, each of said at least two independent trunks having an upstream first opening communicating with said first segment and a downstream second opening, said first element further comprising a third segment connected to and communicating with said downstream second opening of said each of said at least two independent trunks of said second segment, said third segment having a diameter in said deployed state for facilitating access of a second endoprosthesis-forming device through said third segment into engagement in one of said at least two independent trunks for treating a blood vessel downstream therefrom, said first element comprising at least one of a wire and tape, wherein said at least one of said wire and tape is made of a biocompatible alloy having shape memory, and said first, second, and third segments being formed by a continuous one of a single meshworking step and a single knitting step of said at least one of a wire and tape such that there are no gaps between the first segment and the second segment and between said second segment and said third segment; anda second element comprising a leak-proof envelope substantially surrounding said first element including said at least two independent trunks of said second segment, said envelope providing a leak-proof fluid seal about said first element and permitting fluid flow from said upstream end to said downstream end of said first element.
