Claim 0:
1. A catheter system for delivery and deployment of an intravascular device, the catheter system having a distal end and a proximal end, comprising:
an inner tube having a first lumen and an outer surface;
an outer tube having a second lumen and an internal surface, wherein said inner tube extends through said second lumen;
a housing structure at the proximal end of said catheter system, said housing structure having a distal end and a proximal end, wherein the outer tube and inner tube are affixed to the housing structure and form a radial space between the outer surface of the inner tube and the internal surface of the outer tube, and
a retractable sleeve structure positioned in the radial space between the inner tube and outer tube, said retractable sleeve structure comprising a middle tube and a sleeve tip, the middle tube having a proximal end and a distal end, the middle tube coaxially extending substantially along the length of the inner and outer tubes, and the sleeve tip having a distal end sealed to the inner tube and a proximal end fixed to the distal end of the middle tube, wherein in a pre-deployment state, the sleeve tip forms a fold over the intravascular device to form a double layered sheath.
