Abstract
An expandable intraluminal vascular graft is expanded within a blood vessel by an angioplasty balloon associated with a catheter to dilate and expand the lumen of a blood vessel. The graft may be a wire mesh tube.
Claims28
A method for implanting a prosthesis within a body passageway comprising the steps of:
- disposing the prosthesis upon a catheter;
- inserting the prosthesis and catheter within the body passageway by catheterization of said body passageway;
- and
- providing controllable expansion of the prosthesis at a desired location within the body passageway by expanding a portion of the catheter associated with the prosthesis to force the prosthesis radially outwardly into contact with the body passageway, by deforming a portion of the prosthesis with a force in excess of the elastic limit of the portion of the prosthesis, to implant the prosthesis within the body passageway.

A method for expanding the lumen of a body passageway comprising the steps of:
- inserting an intraluminal graft, disposed upon a catheter, into the body passageway until it is disposed adjacent a desired location within the body passageway;
- and
- expanding a portion of the catheter to provide controllable expansion of the intraluminal graft radially, outwardly into contact with the body passageway, by deforming a portion of the intraluminal graft with a force in excess of the elastic limit of the portion of the prosthesis, until the lumen of the body passageway at the desired location in the body passageway has been expanded, whereby the intraluminal graft prevents the body passageway from collapsing and decreasing the size of the expanded lumen, and the intraluminal graft remains in the passageway.
An expandable intraluminal vascular graft, comprising:
- a tubular shaped member having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, at least some of the elongate members intersecting with one another intermediate the first and second ends of the tubular shaped member;
- the tubular shaped member having a first diameter which permits intraluminal delivery of the tubular shaped member into a body passageway having a lumen;
- and
- the tubular shaped member having a second, expanded diameter, upon the application from the interior of the tubular shaped member of a radially, outwardly extending force, which second diameter is variable and controlled by the amount of force applied to the tubular shaped member, at least some of the elongate members being deformed by the radially, outwardly extending force, to retain the tubular shaped member with the second, expanded diameter, whereby the tubular shaped member may be expanded to expand the lumen of the body passageway and remain therein.

An expandable prosthesis for a body passageway, comprising:
- a tubular shaped member having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, at least some of the elongate members intersecting with one another intermediate the first and second ends of the tubular shaped member;
- the tubular shaped member having a first diameter which permits intraluminal delivery of the tubular shaped member into a body passageway having a lumen;
- and
- the tubular shaped member having a second, expanded diameter, upon the application from the interior of the tubular shaped member of a radially, outwardly extending force, which second diameter is variable and controlled by the amount of force applied to the tubular shaped member, at least some of the elongate members being deformed by the radially, outwardly extending force, to retain the tubular shaped member with the second, expanded diameter, whereby the tubular shaped member may be expanded to expand the lumen of the body passageway and remain therein.

An apparatus for intraluminally reinforcing a body passageway, comprising:
- an expandable, tubular shaped prosthesis having first and second ends, and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, the expansion of the prosthesis being controllable;
- and
- a catheter, having an expandable, inflatable portion associated therewith and including means for mounting and retaining the expandable, tubular shaped prosthesis on the expandable, inflatable portion,
- whereby upon inflation of the expandable, inflatable portion of the catheter, the prosthesis is forced radially outwardly into contact with the body passageway to remain therein, and the expansion of the prosthesis is controlled by the expansion of the inflatable portion of the catheter.
