First Claim
Patent Images
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 dimension; and
a fiber extending from the catheter and releasably coupled to a side wall of the expandable device near or at an end of the expandable device to maintain an inner curvature of the expandable device as the expandable device is deployed.

Abstract
A catheter assembly includes an expandable device that is disposed at a distal end of a catheter and expandable toward a fully deployed outer dimension. A fiber extends from the catheter and is releasably coupled to a side wall of the expandable device near or at an end of the expandable device to maintain an inner curvature of the expandable device as the expandable device is deployed.

8. 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 releasably coupled to the catheter and expandable toward a fully deployed outer peripheral dimension; a flexible sleeve extending around the device, the sleeve having a releasable first seam that maintains the sleeve at a first outer peripheral dimension suitable for endoluminal delivery and deployment of the device to a treatment site, and a releasable second seam that limits expansion of the sleeve to a second outer peripheral dimension larger than the first outer peripheral dimension and smaller than the fully deployed outer peripheral dimension after release of the releasable first seam; and a fiber extending from the catheter and releasably coupled to a side wall of the expandable device near or at an end of the expandable device to maintain an inner curvature of the expandable device as the expandable device is deployed. - View Dependent Claims (9, 10, 11, 12, 13, 14)
