Delivery sleeves for multi branch expandable medical devices

A deployment system for a branched endoluminal device, comprising:

• an expandable endoluminal device having an exterior surface and an interior surface defining a sidewall, and including at least a first portion and a second portion expandable from a collapsed delivery diameter configuration toward deployed diameter configurations, wherein the second portion includes one or more openings through the sidewall;
• a first sleeve including first and second edge portions, the first sleeve having a delivery configuration circumferentially wrapped around at least portions of the first and second portions of the endoluminal device with the first and second edge portions releasably coupled to define a first sleeve seamline substantially opposite the one or more openings, and wherein the first sleeve is attached to the endoluminal device at a plurality of attachment locations circumferentially located sufficiently close to the first sleeve seamline to prevent the first sleeve from substantially covering any of the one or more openings after the first and second edge portions are released and the first and second portions of the endoluminal device have expanded to the deployed diameter configurations;
• and
• a second sleeve including first and second edge portions, the second sleeve having a delivery configuration circumferentially wrapped around the first portion of the endoluminal device with the first and second edge portions releasably coupled to define a second sleeve seamline adjacent to the first sleeve seamline, and wherein the second sleeve is attached to the endoluminal device at a plurality of attachment locations circumferentially located sufficiently close to the first seamline to prevent the second sleeve from substantially covering any of the one or more openings after the first and second edge portions are released and the second portion of the endoluminal device has expanded to the deployed diameter configuration.
