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.
