1. A method of deploying a stent graft between proximal and distal landing sites axially spaced along the lumen of a patient, the method comprising the following steps:
- a. selecting a flexible stent graft having spaced proximal and distal ends, the proximal and distal ends being spaced further apart than the proximal and distal landing sites, b. introducing the proximal end of the stent graft into the lumen of the patient, with the distal end trailing behind;
c. situating;
(1) the proximal end of the stent graft at the proximal landing site, and (2) the distal end of the stent graft away from the distal landing site, such that the distal landing site is between the proximal landing site and the distal end of the stent graft; and
d. subsequently moving the distal end of the stent graft toward the proximal end until it is situated at the distal landing site.

Abstract
A graft is provided with a flexible sheet (10) of graft material to which is sewn a reinforcing wire (12), preferably of shape-memory alloy. Sewing of the wire (12) is carried out while the sheet (10) is substantially planar, thus by conventional embroidery machines. The sheet (10) is subsequently rolled into a tubular shape.

17. A method of deploying a stent graft between proximal and distal landing sites axially spaced along the lumen of a patient, wherein the stent graft:
-
(1) has spaced proximal and distal ends, the proximal and distal ends being spaced further apart than the proximal and distal landing sites, and (2) is axially compressible to allow the proximal and distal ends to be more closely spaced, the method comprising the following steps;
a. firstly introducing the proximal end of the stent graft into the lumen of a patient, with the distal end trailing behind;
b. secondly situating the proximal end of the stent graft at the proximal landing site;
c. thirdly advancing the distal end of the stent graft toward the proximal landing site until the distal end is situated at the distal landing site; and
d. fourthly releasing the distal end of the stent graft at the distal landing site.

18. A method of deploying a stent graft between proximal and distal landing sites axially spaced along the lumen of a patient, wherein the stent graft:
-
I. has spaced proximal and distal ends, the proximal and distal ends being spaced further apart than the proximal and distal landing sites;
II. is axially compressible to allow the proximal and distal ends to be more closely spaced; and
III. is provided in combination with;
i. a deployment sheath wherein the stent graft may be situated with the stent graft being radially compressed, the stent graft radially expanding when released from the deployment sheath;
ii. proximal attachment means for releasably engaging the proximal end of the stent graft, the proximal attachment means extending along the deployment sheath;
iii. distal attachment means for releasably engaging the distal end of the stent graft, the distal attachment means extending along the deployment sheath;
the method comprising the following steps;
a. introducing the deployment sheath into the lumen of a patient with;
(1) the deployment sheath having the stent graft therein, and (2) the proximal end of the stent graft leading the distal end;
b. locating the deployment sheath within the lumen such that the proximal end of the stent graft is situated at the proximal landing site;
c. withdrawing the deployment sheath from the proximal end of the stent graft while the proximal attachment means maintains the proximal end of the stent graft at the proximal landing site; and
d. withdrawing the deployment sheath from the distal end of the stent graft while the distal attachment means maintains the distal end of the stent graft at the distal landing site. - View Dependent Claims (19, 20, 21)
