Abstract

An intraluminal grafting system includes a hollow graft which has a proximal staple positioned proximate its proximal end and a distal staple adapted proximate its distal end. The system includes a capsule for transporting the graft through the lumen and for positioning the proximal end of the graft upstream in a lumen which may be a blood vessel or artery. A tube is connected to the capsule and extends to exterior the vessel for manipulation by the user. A catheter is positioned within the tube to extend from the cavity and through the graft to exterior the body. The catheter has an inflatable membrane or balloon proximate the distal end thereof which is in communication via a channel with inflation and deflation means located exterior the vessel. With the inflatable membrane deflated, the capsule is positioned in the lumen and manipulated to a desired location. The inflatable membrane is manipulated by the rod away from the graft. The force exerted by the inflatable membrane and the structure of the staples urges the staples in the vessel wall, retaining the graft in position. The remainder of the intraluminal grafting system is then removed from the corporeal vessel.

Claims

1. A method for implanting a prosthesis within a body lumen, the method comprising:

intraluminal emplacement of a vascular graft, said vascular graft being disposed about a catheter having an inflatable member;

expanding said inflatable member thereby expanding said vascular graft radially outwardly into contact with said body lumen; and

providing a substantially fluid-tight seal between said vascular graft and an interior surface of said body lumen.

2. A method for implanting a prosthesis within a body lumen, the method comprising:

intraluminal emplacement of a vascular graft, said vascular graft being disposed about a catheter system having an inflatable member and an inflation system for inflating and deflating said inflatable member;

expanding said vascular graft to conform to an interior surface of said body lumen by inflating said inflatable member with said inflation systems; and

providing a substantially fluid-tight seal between said vascular graft and said interior surface of said body lumen.

3. The method of claim 2, further comprising:

deflating said inflatable member after providing said substantially fluid-tight seal.

4. A method for intraluminal emplacement of a prosthesis in a body lumen, the method comprising:

intraluminal emplacement of a prosthesis, said prosthesis being disposed about a catheter system having an inflatable member and an inflation system for inflating and deflating said inflatable member;

positioning said prosthesis across an aortic aneurysm;

expanding said prosthesis to conform to an interior surface of said body lumen by inflating said inflatable member with said inflation system;

providing a substantially fluid-tight seal between said prosthesis and said interior surface of said body lumen adjacent said aortic aneurysm;

deflating said inflatable member; and

withdrawing said catheter system from said body lumen.

5. A method for intraluminal emplacement of a prosthesis in a body lumen, the method comprising:

forming an opening in a body lumen;

inserting a catheter system through said opening into said body lumen;

said catheter system having an inflatable member and an inflation system for inflating said inflatable member;

intraluminal emplacement of a prosthesis, said prosthesis being disposed about said catheter system;

positioning said prosthesis across an aortic aneurysm;

expanding at least a portion of said prosthesis to conform to an interior surface of said body lumen by inflating said inflatable member with said inflation system;

providing a substantially fluid-tight seal between said prosthesis and said interior surface of said body lumen adjacent said aortic aneurysm;

deflating said inflatable member; and

withdrawing said catheter system from said body lumen.

6. A method for implanting a prosthesis within a body lumen, the method comprising:

intraluminal emplacement of a vascular graft within a body lumen;

expanding an inflatable member disposed within said vascular graft thereby expanding said vascular graft radially outwardly into contact with said body lumen; and

providing a substantially fluid-tight seal between said vascular graft and an interior surface of said body lumen.

7. The method of claim 6, wherein said inflatable member is disposed on a catheter positioned within said body lumen.

8. The method of claim 7, further comprising withdrawing said catheter from said body lumen after providing said substantially fluid-tight seal.

9. A method for implanting a prosthesis within a body lumen, the method comprising:

intraluminal emplacement of a vascular graft mounted on a guide disposed within a body lumen;

expanding said vascular graft to conform to an interior surface of said body lumen by inflating an inflatable member disposed within said vascular graft; and

providing a substantially fluid-tight seal between said vascular graft and said interior surface of said body lumen.
