1. An assembly comprising:
- a catheter;
an expandable device disposed in a collapsed configuration at an end of the catheter;
a first releasable sleeve coaxially covering a proximal portion of said expandable device; and
a second releasable sleeve coaxially covering a distal portion of said expandable device, said second sleeve being rotatably constrained relative to the catheter,wherein said first sleeve overlaps a portion of said second sleeve and said first sleeve and second sleeve are rotatably constrained relative to each other.

Abstract
The present disclosure describes an assembly comprising a catheter, an expandable device in a collapsed configuration on the catheter, a first releasable sleeve coaxially covering a proximal portion of the device, and a second releasable sleeve coaxially covering a distal portion of the device, wherein first and second sleeves overlap and are rotatably constrained relative to each other, and wherein the second sleeve is rotatably constrained relative to the catheter. During deployment, rotation of the catheter causes rotation of the second sleeve and the device for angular radial orientation. After deployment, the first sleeve may remain implanted in the patient.

11. A method for deploying an expandable device in a patient comprising:
-
moving an assembly in the patient to a treatment site, said assembly comprising; a catheter;
the expandable device disposed in a collapsed configuration at an end of the catheter;
a first releasable sleeve coaxially covering a proximal portion of said expandable device; and
a second releasable sleeve coaxially covering a distal portion of said expandable device, said second sleeve being rotatably constrained relative to the catheter, wherein said first sleeve overlaps a portion of said second sleeve and said first sleeve and second sleeve are rotatably constrained relative to each other;releasing said first sleeve; optionally expanding said proximal portion of said expandable device; rotating said catheter to cause rotation of said second sleeve to achieve a desired angular radial orientation of said expandable device; releasing said second sleeve; and optionally expanding unexpanded portions of said expandable device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
