Problems solved by technology

While the use of such sleeves provides a convenient way to constrain the stent graft, sleeves may give rise to other problems or issues.
For example, it may be difficult to position a stent graft that is constrained by a biocompatible sleeve for implanting within the treatment area of the vasculature.
Further, it may be difficult to remove or expand the sleeve to allow for expansion of the stent graft.
Finally, orienting or locating a sleeve-constrained stent graft after it has been expanded may be difficult.

Embodiment Construction

[0016]While the present disclosure describes a number of embodiments, it will be understood that the disclosure is not limited to these embodiments. Instead, it is intended to cover all alternatives, modifications, and equivalents as may be included within the spirit and scope of the disclosure as described and claimed.

[0017]Various embodiments of the present disclosure comprise a catheter assembly configured to deliver an expandable implant to a treatment area of the vasculature of a patient. In accordance with embodiments of the disclosure, an expandable implant is constrained by one or more sleeves. When the sleeves are expanded or removed, one or more target portions of the expandable implant can be exposed. In various embodiments, the target portion or portions comprise side branch fenestrations or fenestratable portions. Such target portions may be revealed between adjacent sleeves or between the edges of a single sleeve.

[0018]With initial reference to FIG. 1, a catheter assem...

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.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 414,253, entitled “SEGMENTED CONSTRAINING SLEEVES FOR EXPANDABLE MEDICAL DEVICES” filed Nov. 16, 2010, which is hereby incorporated by reference in its entirety.BACKGROUND[0002]1. Field[0003]The present disclosure relates generally to the transcatheter delivery and remote deployment of implantable medical devices.[0004]2. Discussion of the Related Art[0005]Endoluminal devices used to treat a treatment area of the vasculature of a patient are typically delivered via a catheter assembly. Such endoluminal devices may comprise, for example, expandable implants. One common type of expandable implant is the stent graft. Stent grafts may have a reduced diameter, collapsed configuration for delivery to the patient's vasculature, then be expanded once the treatment area of the vasculature is reached. Stent grafts may be constrained in the collapsed configuration by a bio...
