SLEEVES FOR EXPANDABLE MEDICAL DEVICES
First Claim
1. A device for treating a vessel comprising:
- an expandable stent graft having a main lumen and a target portion;
a primary sleeve wrapped circumferentially around the expandable stent graft, wherein the primary sleeve comprises a sheet of material having first and second major surfaces and a plurality of openings extending from the first major surface to the second major surface; and
a primary coupling member cooperating with the openings for releasably coupling portions of the sheet to one another to constrain the expandable stent graft in a collapsed configuration,wherein the primary sleeve includes a lateral opening proximate to the target portion.

Abstract
The present disclosure describes treatment of the vasculature of a patient with an expandable implant. The implant is constrained to a reduced delivery profile for delivery within the vasculature by at least one sleeve. The implant may be constrained to other diameters, such as an intermediate configuration having a diameter larger than the delivery profile and smaller than the deployment diameter. The sleeves may be expanded, allowing for expansion of the diameter of the expandable implant, by disengaging a coupling member from the sleeve or sleeves from outside of the body of the patient. The expandable implant may comprise a number of side branch fenestrations or fenestratable portions.

9. A device for treatment of a vessel comprising:
-
an expandable implant having a main lumen and at least one target portion; at least two sheets of material, each wrapped circumferentially around the expandable implant forming at least two adjacent tubes; each tube having at least one tube end adjacent to another tube end; each sheet having first and second major surfaces and a plurality of openings extending from the first major surface to the second major surface; and a coupling member cooperating with the openings for releasably coupling portions of each sheet together to constrain the expandable implant in a collapsed configuration. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A device for treatment of a vessel comprising:
-
an expandable implant having a main lumen and at least one target portion; at least two sleeves; a collapsed configuration, wherein each of the at least two sleeves comprise a sheet of material wrapped circumferentially around the expandable implant forming a tube having at least one tube end adjacent to another tube end;
each sheet having first and second major surfaces and a plurality of openings extending from the first major surface to the second major surface; and
a coupling member cooperating with the openings for releasably coupling portions of each sheet together to constrain the expandable implant in a collapsed configuration; andan expanded configuration, wherein upon disengagement of the coupling member, the expandable implant is expanded and the at least one target portion is positioned between one tube end and the other adjacent tube end. - View Dependent Claims (20)
