1. A system for delivering and deploying an expandable endoluminal prosthesis, the system comprising:
- an elongate sheath having a proximal end, a distal end, and an inner lumen;
a delivery catheter having a proximal end and a distal end, wherein the delivery catheter is slidably disposed within the sheath lumen; and
an operating mechanism comprising a contractible air vessel having an expanded length and a contracted length, the air vessel coupling the sheath and the delivery catheter, so that pneumatic contraction of the air vessel causes the sheath to retract proximally over the delivery catheter.

Abstract
A system for delivering and deploying an expandable endoluminal prosthesis comprises a delivery catheter and a sheath. The delivery catheter has a proximal end and a distal end and is slidably disposed within a lumen of the sheath. An operating mechanism comprises a contractible air vessel that couples the sheath and the delivery catheter so that contraction of the air vessel causes the sheath to retract proximally over the delivery catheter. Additional aspects of the invention include a method of deploying an expandable endoluminal prosthesis.

12. A pneumatic operating mechanism for an endoluminal prosthesis delivery and deployment device having a sheath and a delivery catheter slidingly disposed within a lumen of the sheath, the operating mechanism comprising:
-
a contractible air vessel having a proximal end a distal end, an expanded length and a contracted length;
wherein the proximal end of the air vessel is engageable with the delivery catheter and the distal end of the air vessel is engageable with the sheath so that contraction of the air vessel causes the sheath to retract proximally over the delivery catheter. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of deploying an expandable endoluminal prosthesis, the method comprising the steps of:
-
providing a prosthesis delivery and deployment system comprising an elongate sheath having a proximal end, a distal end, and an inner lumen and a delivery catheter having a proximal end and a distal end, wherein the delivery catheter is slidably disposed within the sheath lumen;
providing an operating mechanism comprising a contractible air vessel having an expanded length and a contracted length, wherein the air vessel couples the sheath and the delivery catheter; and
pneumatically contracting the air vessel to cause the sheath to retract over the delivery catheter. - View Dependent Claims (20)
