Claim Text:
1. A catheter assembly comprising: a catheter having opposite proximal and distal ends, the catheter having a lumen extending between the proximal and distal ends of the catheter; an expandable device disposed at the distal end of the catheter and expandable toward a fully deployed outer peripheral dimension, the expandable device having a first end and an opposite second end, the expandable device having an outer surface and an opposite inner surface defining a flow lumen extending between the first end and second end; and a flexible sleeve extending around the outer surface of the expandable device, wherein the flexible sleeve has a first releasable seam that maintains the flexible sleeve at a first dimension suitable for endoluminal delivery of the expandable device to a treatment site, and a second releasable seam, disposed between the catheter and the first releasable seam and radially aligned therewith, that maintains the flexible sleeve at a second dimension larger than the first dimension and smaller than the fully deployed outer peripheral dimension to allow blood flow through the flow lumen during positioning of the expandable device after release of the first releasable seam and prior to release of the second releasable seam.
