Two-part expanding stent graft delivery system
First Claim
1. A system for implanting a prosthesis, comprising:
- a delivery device having;
a handle;
an inner lumen slidably disposed in said handle between a retracted position and an extended position, said inner lumen having a distal end and a tip at said distal end of said inner lumen;
an intermediate lumen slidably disposed about said inner lumen and having a distal end;
a relatively flexible prosthesis sheath connected to said distal end of said intermediate lumen; and
a relatively stiff outer lumen axially fixedly connected to said handle about said intermediate lumen, said outer lumen having a length only long enough to be inserted in a patient'"'"'s aorta no further than the patient'"'"'s celiac axis.

Abstract
A delivery system for endovascularly delivering a prosthesis along a guidewire to a curved implantation site includes a delivery device having control handle and an inner lumen slidably disposed in the handle between a retracted position and an extended position. The inner lumen has a distal end and a tip at the distal end of the inner lumen. An intermediate lumen is slidably disposed about the inner lumen and has a distal end. A relatively flexible prosthesis sheath is connected to the distal end of the intermediate lumen and a relatively stiff outer lumen is axially fixedly connected to the handle about the intermediate lumen. The outer lumen has a length only long enough to be inserted in a patient'"'"'s aorta no further than the patient'"'"'s celiac axis.

1. A system for implanting a prosthesis, comprising:
a delivery device having;
a handle;
an inner lumen slidably disposed in said handle between a retracted position and an extended position, said inner lumen having a distal end and a tip at said distal end of said inner lumen;
an intermediate lumen slidably disposed about said inner lumen and having a distal end;
a relatively flexible prosthesis sheath connected to said distal end of said intermediate lumen; and
a relatively stiff outer lumen axially fixedly connected to said handle about said intermediate lumen, said outer lumen having a length only long enough to be inserted in a patient'"'"'s aorta no further than the patient'"'"'s celiac axis. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A system for implanting a prosthesis in a patient at an implantation site, comprising:
-
a delivery device having;
a handle defining a longitudinal axis;
an inner lumen slidably disposed in said handle between a retracted position and an extended position, said inner lumen having a distal end and a tip at said distal end of said inner lumen;
an intermediate lumen slidably disposed about said inner lumen in said handle and having a distal end;
a relatively flexible prosthesis sheath connected to said distal end of said intermediate lumen; and
a relatively stiff outer lumen axially fixedly connected to said handle about said intermediate lumen and said sheath, said outer lumen having a length only long enough to be inserted in the patient'"'"'s aorta no further than the patient'"'"'s celiac axis;
said inner lumen, said intermediate lumen and said sheath comprising a delivery assembly for positioning the prosthesis in the implantation site; and
when said delivery assembly positions the prosthesis in the implantation site, rotation of a portion of said handle about said longitudinal axis causes a corresponding rotation of said delivery assembly in the implantation site while said outer lumen remains substantially rotationally stable.

34. A system for traversing a guidewire and implanting a prosthesis at an implantation site in a patient, comprising:
-
a prosthesis; and
a delivery device having;
a handle;
a prosthesis delivery assembly slidably disposed in said handle between a retracted position and an extended position, said delivery assembly having;
at least one hollow first lumen for slidably receiving therein the guidewire;
a hollow second lumen slidably disposed about said at least one first lumen;
a hollow third lumen slidably disposed about said second lumen and having a distal end;
a relatively flexible hollow prosthesis sheath connected to said distal end of said third lumen and disposed about said at least one first lumen and said second lumen, said sheath holding said prosthesis therein at least prior to implantation of said prosthesis at the implantation site; and
a relatively stiff outer lumen;
having a length only long enough to be inserted in a patient'"'"'s aorta no further than the patient'"'"'s celiac axis;
slidably disposed about said at least one first lumen, and said third lumen and slidably disposed about said sheath when said sheath is at least partially inside said outer lumen;
having a proximal end connected to said handle to axially fix said outer lumen with respect to said control handle. - View Dependent Claims (35)

an intermediate lumen slidably disposed about said inner lumen in said handle and having a distal end;
a relatively flexible prosthesis sheath connected to said distal end of said intermediate lumen; and
a relatively stiff outer lumen axially fixedly connected to said handle about said intermediate lumen, said outer lumen having a length no greater than 65 cm.

37. A system for implanting a prosthesis, comprising:
-
a delivery device having;
a handle;
at least one inner lumen slidably disposed in said handle between a retracted position and an extended position, said inner lumen having a distal end and a tip at said distal end of said inner lumen;
at least one intermediate lumen slidably disposed about said inner lumen in said handle and having a distal end;
a relatively flexible prosthesis sheath connected to said distal end of said intermediate lumen; and
a relatively stiff outer lumen axially fixedly connected to said handle about said intermediate lumen, said outer lumen having a length only long enough to be inserted in a patient'"'"'s aorta no further than the patient'"'"'s celiac axis;
said sheath lumen, said inner lumen, and said prosthesis lumen extend distally from said distal end of said outer lumen to an extended position; and
said sheath lumen retracts proximally when at least one of said inner lumen and said intermediate lumen is in said extended position. - View Dependent Claims (38)
