Abstract

A system and components for treating aortic aneurysms includes a reinforcing graft and fittings for securing the graft to a host vessel and to branch vessels, for example the iliac and renal arteries. Combinations of fittings and rings or other compression mechanisms secure vessels or grafts frictionally, for end-end or end-side couplings. A variety of tools are disclosed for manipulating retaining rings, everting portions of grafts or vessels in the course of coupling them to fittings, and clamping fittings while positioning the retaining rings.

Independent Claims | See all claims (31)

  1. 1. An aneurysm treatment system comprising: a reinforcing graft defining a first luinen, said graft having a first end to which a first inert fitting is affixed, said graft having a second end to which a second inert fitting is affixed, a first compression mechanism adapted to affix said first fitting to a vessel at a first vessel location distal to a vessel aneurysm, and a second compression mechanism adapted to affix said second fitting to the vessel at a second vessel location proximal to said aneurysm.
  2. 17. An aneurysm treatment system comprising: a reinforcing graft defining a first lumen, said graft having a first end to which a first inert fitting is affixed, said graft having a: second end to which a second inert fitting is affixed, a first compression mechanism adapted to affix said first fitting to a vessel at a first vessel location distal to a vessel aneurysm, a second compression mechanism adapted to affix said second fitting to the vessel at a second vessel location proximal to said aneurysm, and an extension graft defining a second lumen, integrated to and extending from the reinforcing graft, and adapted to affix to at least one branching vessel such that a passage is created by said first lumen and said second lumen for fluid flow from the reinforcing graft through the extension graft to the at least one branching vessel.
  3. 26. A method for treating abdominal aortic aneurysms, comprising: (a) inserting a reinforcing graft having an inert fitting on each of a proximal and at least one distal reinforcing graft end into a lumen of an abdominal aorta, (b) positioning each reinforcing graft fitting in the lumen such that the reinforcing graft envelops an aneurysm in the abdominal aorta, (c) securing the at least one distal fitting to a vessel wall of the abdominal aorta, (d) creating openings in the abdominal aorta vessel wall and reinforcing graft wall near a branching vessel, (e) dilating the openings and positioning a delivery sheath through the abdominal aorta vessel wall and the reinforcing graft wall, (f) advancing an extension graft with an attached extension graft fitting through a delivery sheath, (g) securing the extension graft fitting to the reinforcing graft wall and the abdominal aorta vessel wall, and (h) securing the proximal reinforcing graft fitting to the abdominal aorta vessel wall.
