A multi-component branching expandable supportive endoluminal graft comprising: a plurality of expandable supportive endoluminal components (101,108,115) which are capable of individual deployment at a selected location within a body vessel, each said supportive endoluminal graft component being radially compressible for endoluminal insertion and radially expandable for deployment at a desired location within a body vessel; characterised in that one of said expandable supportive endoluminal components is a trunk component (101), said trunk component being generally tubular and having a first portion (118) with a given diameter and a second portion (119) including a longitudinally disposed indent (124) generally defining at least two leg portions (109,113), each with a diameter less than said given diameter, and each said leg portion has a leg opening (126,127); at least one other of said expandable supportive endoluminal components is a generally cylindrical supportive leg component (108,115); and said generally cylindrical supportive leg component, when said leg component and trunk component are deployed within the body vessel, is positioned within one of said leg portions of the trunk component. <IMAGE> |
