Abstract
Systems and method for treating aneurysms are provided which utilize formulations that form polymer foams in situ. The formulations generally have a buoyancy greater than or less than blood, and either float to the top of the aneurysm and foam from the top down or sink to the bottom and foam from the bottom up.
Claims19
A system for treating a patient, comprising:
- an endoprosthesis configured to span an aneurysm;
- and
- a formulation adapted to form a polymer foam when exposed to blood, the formulation configured to float in blood.
A system for treating a patient, comprising:
- an endoprosthesis configured to span an aneurysm;
- and
- a formulation adapted to form a polymer foam when exposed to a body fluid, the formulation having a buoyancy less than that of blood.
A system for treating a patient, comprising:
- an endoprosthesis configured to span an abdominal aortic aneurysm;
- a formulation configured to form a polymer foam within the abdominal aortic aneurysm;
- and
- a delivery catheter insertable through one of an inferior mesenteric artery, a lumbar artery, a fenestration within the endoprosthesis and a space between the endoprosthesis and a wall of a blood vessel adjoining the abdominal aortic aneurysm,
- wherein the formulation is configured to migrate away from the delivery catheter and to form a foam within the abdominal aortic aneurysm that expands toward the delivery catheter.
