US 9,066,824 B2 · Method and apparatus for endovascular therapy of aortic pathology

Abstract

Assemblies, devices, and methods for positioning the same proximate a target site within a body lumen are provided. The assembly includes first and second components that can function independently of one another to address a patient's vascular abnormalities or can cooperate to form an assembly. The assembly is designed to address aortic pathologies near clusters of arterial branches in a way that allows blood to continue flowing to the arterial branches during the procedure while providing an adequate landing zone for the adjoining component. One of the components may include a tapered portion near one end that can be received by a corresponding end of the other component. Alternatively, one of the components may include an invaginated end that is able to receive a corresponding end of the other component such that the position of each component is substantially fixed with respect to the other.

Dependent claims

A vascular assembly for treating a target site within a body lumen comprising:

a first component defining a first end, a second end, and a lumen extending therebetween;
and
a second component defining a first end, a second end, and a lumen extending therebetween, wherein the second end of the second component is configured to receive the second end of the first component,
wherein the first component is configured to engage an inner surface of a vessel wall proximate at least one arterial branch at the target site,
wherein the second component is configured to engage an inner surface of the vessel wall at the target site,
wherein each of the first and second components is independently deployable to the target site and is configured for use at the target site both independently of the other component and in cooperation with the other component, and
wherein at least one of the first or second components defines at least one fenestration configured for extending a debranching limb into a corresponding arterial branch.
