Endoprosthesis assemblies and methods to use the same

An endoprosthesis assembly, comprising:

• an endoprosthesis having an impermeable inner wall;
• a first balloon at or near a distal end of the endoprosthesis and a second balloon at or near the proximal end of the prosthesis;
• and
• a first tube defining one or more tube openings positioned on a relative outside of the inner wall, the one or more tube openings are exposed along a relative outside of the endoprosthesis assembly;
• wherein the endoprosthesis assembly is configured to isolate an aneurysm sac of a luminal organ when positioned therein and the first balloon and the second balloon are inflated, and wherein the endoprosthesis assembly is further configured to facilitate removal of blood present within the aneurysm sac using the one or more tube openings.

A method for using an endoprosthesis assembly, the method comprising the steps of:

• delivering an endoprosthesis assembly within a vessel of a patient at or near the site of an aneurysm sac of a vessel aneurysm, the endoprosthesis assembly comprising:
• an endoprosthesis having an impermeable inner wall;
• a first balloon at or near a distal end of the endoprosthesis and a second balloon at or near the proximal end of the prosthesis;
• a first tube defining one or more tube openings positioned on a relative outside of the inner wall, the one or more tube openings are exposed along a relative outside of the endoprosthesis assembly;
• and
• a catheter having a distal catheter end, a proximal catheter end, and defining a first catheter lumen and a second catheter lumen therethrough, wherein the distal catheter end of the catheter is configured to be removably coupled to the endoprosthesis;
• and
• operating an inflation/deflation source in communication with the first catheter lumen to inflate the distal balloon and the proximal balloon to isolate the aneurysm sac and prevent fluid within the aneurysm sac from flowing past the distal balloon and the proximal balloon.
