1. A vessel occluder for providing permanent occlusion of a vessel in a person, the vessel having an inner wall surface and having a body fluid flowing therethrough, comprising:
- at least one metallic tubular shaped member, having an outer surface, an interior and first and second open ends, the tubular shaped member having a first diameter which permits intraluminal delivery of the at least one tubular shaped member into the vessel to be occluded;
a flexible closure member, attached to the first open end of the at least one tubular member, which seals the first open end, the closure member having a first diameter, which is substantially the same as the at least one tubular shaped member first diameter; and
the at least one tubular shaped member and at least a portion of the flexible closure member having a second expanded permanent 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 an amount of force applied to the tubular shaped member, which force deforms at least a portion of the at least one tubular shaped member to permanently retain the at least one tubular shaped member and the portion of the closure member with the second expanded permanently diameter, whereby the closure member is disposed in sealing engagement with the inner wall surface of the vessel and occludes the vessel to prevent the body fluid from flowing past the closure member.

11. A method for permanently occluding a vessel in a person, the vessel having an inner wall surface and a body fluid flowing therethrough, comprising the steps of:
-
attaching a flexible closure member to a first open end of at least one metallic, generally tubular shaped, radially expandable stent, the flexible closure member being provided with a generally tubular shaped cross-sectional configuration, with inner and outer wall surfaces and first and second ends, the first closure member end being closed and the second closure end being open and in fluid communication with the first open end of the stent; disposing the at least one stent and flexible closure member upon a catheter; inserting the flexible closure member, at least one stent and catheter within the vessel to be occluded; and expanding the at least one stent to permanently dispose at least a portion of the outer surface of the flexible closure member in a sealing relationship with the inner wall surface of the vessel, whereby the vessel is occluded and body fluid is prevented from flowing past the flexible closure member. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An apparatus for providing permanent occlusion of a vessel in a person, the vessel having an inner wall surface and having a body fluid flowing therethrough comprising:
-
a catheter, having an expandable, inflatable portion associated therewith, at least one metallic tubular shaped member, having an outer surface an interior and first and second open ends, the tubular shaped member having a first diameter which permits intraluminal delivery of the at least one tubular shaped member into the vessel to be occluded, the at least one tubular shaped member being disposed upon the expandable, inflatable portion of the catheter; a flexible closure member, attached to the first open end of the at least one tubular member, which seals the first open end, the closure member having a first diameter, which is substantially the same as the at least one tubular shaped member first diameter; and the at least one tubular shaped member and at least a portion of the flexible closure member having a second expanded diameter, upon an application from the interior of the tubular shaped member of a radially outwardly extending force, which second diameter is variable and controlled by an amount of force applied to the tubular shaped member, which force deforms at least a portion of the at least one tubular shaped member to retain the at least one tubular shaped member and the portion of the closure member with the second expanded diameter, whereby the closure member is disposed in sealing engagement with the inner wall surface of the vessel and occludes the vessel to prevent the body fluid from flowing past the closure member. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
