Intraluminal graft assembly and vessel repair system
First Claim
Patent Images
1. A system for repairing a vessel of a patient, said system comprising:
- a deployment device comprising a first sleeve having a proximal end, a distal end, and an inner surface defining a first lumen;
a second sleeve extending coaxially with the first sleeve and having a proximal end, a distal end, an outer surface and defining a second lumen, the second sleeve disposed in the first lumen to form an annular space between the inner surface of the first sleeve and the outer surface of the second sleeve; and
a driving member disposed in the second lumen;
a support frame comprising a tubular structure having a length, a distal end, a proximal end, and at least one connector on the distal end, the support frame substantially disposed in the second lumen such that the connector extends beyond the distal ends of the first and second sleeves; and
a graft attached to the connector and disposed substantially in the annular space.

Abstract
An intraluminal graft assembly is provided. In one embodiment, the assembly comprises a support frame having first, radially smaller and second, radially larger configurations. A graft is attached to the support frame at one end by connectors and is not connected to the other end. The graft extends along only a fractional length of the support frame when in the first configuration, and substantially along the entire length of the support frame when in the second configuration. A vessel repair system is also provided. In the system, a driving member is positioned to force the support frame from the first configuration to the second configuration.

10. A method of deploying a graft in a vessel, said method comprising:
-
providing a system comprising a first sleeve having a proximal end, a distal end, and an inner surface defining a first lumen;
a second sleeve extending coaxially with the first sleeve and having a proximal end, a distal end, an outer surface, and defining a second lumen, the second sleeve disposed in the first lumen to form an annular space between the inner surface of the first sleeve and the outer surface of the second sleeve; and
a driving member disposed in the second lumen and having a driving end and an operating end near the proximal end of the first sleeve;
a support frame comprising a tubular structure having a length, a distal end, a proximal end, and at least one connector on the distal end, the support frame substantially disposed in the second lumen such that the connector extends beyond the distal ends of the first and second sleeves; and
a graft attached to the distal end of the support frame by the connector and not connected to the proximal end of the support frame, the graft being disposed substantially in the annular space; and
manipulating the operating end of the driving member such that the driving end forces the support frame out of the second lumen and the graft out of the annular space. - View Dependent Claims (11, 12)
