Sleeve for an endoluminal device having an aperture for portal access of an implantable device

An endoluminal device including:

• an implantable device that is self-expanding and transitionable between a collapsed, delivery configuration, an intermediate deployment configuration having a greater diameter than the collapsed, delivery configuration, and an expanded, deployed configuration having a greater diameter than the collapsed, delivery configuration and the intermediate deployment configuration, the implantable device having a first end portion, a second end portion, and an intermediate portion located between the first and second end portions, the intermediate portion having a plurality of openings with a sidewall of the implantable device and providing access to an inner lumen of the implantable device, the plurality of openings including at least a first opening, a second opening, and a third opening;
• and
• a constraining sleeve removably disposed around the implantable device in the collapsed, delivery configuration and the intermediate deployment configuration, the constraining sleeve having a single aperture aligning with the plurality of openings such that the single aperture provides access from an exterior to the inner lumen in the collapsed, delivery configuration and the intermediate deployment configuration, wherein the single aperture extends from a first exterior lateral edge of the first opening to a second exterior lateral edge of the second opening when the implantable device is in the intermediate deployment configuration, wherein partially deploying the constraining sleeve from the implantable device is operable to transition the implantable device from the collapsed, delivery configuration to the intermediate deployment configuration, and entirely deploying the constraining sleeve from the implantable device is operable to transition the implantable device from the intermediate deployment configuration to the expanded, deployed configuration.

A method of treatment comprising:

• delivering an endoluminal device in a vasculature, the endoluminal device comprising an implantable device, a secondary constraining sleeve disposed around the implantable device, and a primary constraining sleeve disposed around the secondary constraining sleeve such that the implantable device is in a collapsed, delivery configuration;
• partially deploying the implantable device by removing the primary constraining sleeve from the secondary constraining sleeve, wherein, in a partially deployed configuration, an intermediate portion of the implantable device located between a first end portion and a second end portion of the implantable device expands through an aperture of the secondary constraining sleeve and beyond an outer surface of the secondary constraining sleeve, the intermediate portion having at least one opening in a sidewall providing access to an inner lumen of the implantable device, and the aperture aligning with at least a portion of the at least one opening with the sidewall, the aperture providing access from an exterior to the inner lumen in the partially deployed configuration while the secondary constraining sleeve restrains at least a portion of the implantable device in the partially deployed configuration;
• and
• fully deploying the implantable device by removing the secondary constraining sleeve from the implantable device, wherein, in an expanded, deployed configuration, the implantable device has a greater cross-sectional distance at the first end portion and at the second end portion than at the intermediate portion.
