Abstract:
1. A branch vessel prosthesis for placement at least partially between a main vessel and a branch vessel of a patient, the branch vessel prosthesis comprising: a graft including a generally tubular body of a biocompatible material, the graft having proximal and distal regions, a central region disposed between the proximal and distal regions, and a lumen extending between the proximal and distal regions; at least one stent coupled to the proximal region of the graft, where the proximal region of the graft includes a generally straight configuration in an expanded deployed state that is substantially parallel to a longitudinal axis of a main vessel; and at least one stent coupled to the distal region of the graft, where the distal region of the graft includes a generally straight configuration in the expanded deployed state that is substantially parallel to a branch vessel, where a curvature of the central region varies an angle in which the distal region of the graft is disposed relative to the proximal region of the graft, and where an outer diameter at the proximal region of the graft is greater than an outer diameter at the distal region of the graft in the expanded deployed state, and where the proximal region of the branch vessel prosthesis is disposed within a main vessel prosthesis.
