Hybrid graft for therapy of aortic pathology and associated method

摘要

Vascular devices and methods for addressing aortic pathologies are provided that facilitate hemostasis at the junctions of the ends of the device with the native aorta or other vessels to minimize or eliminate the risk of endoleaks. One or both ends of the device may include inner and outer skirts that are configured to receive a section of native blood vessel therebetween. The outer skirt may be flared in some cases or rolled up prior to placement at and engagement with the blood vessel to provide clearance for joining the blood vessel to the inner skirt of the device, such as via sutures. Once engaged, the outer skirt is disposed such that the blood vessel is between the inner and outer skirts. Devices and associated methods are also described that allow endografts to be deployed and engaged with an end of the device in areas with insufficient landing zones.

主权项

1. A vascular device for treating a target site within a body lumen, wherein the vascular device is configured for placement between first and second sections of a patient's native blood vessel, the vascular device comprising:
a first end configured to be attached to the first section of the native blood vessel; a second end configured to be attached to the second section of the native blood vessel; and a lumen extending between the first and second ends, wherein the lumen is defined by a wall, wherein the wall splits proximate at least one of the first or second ends to form an inner skirt and an outer skirt, wherein the outer skirt at least partially surrounds the inner skirt, and wherein the inner and outer skirts are spaced from each other and are thereby configured to receive a portion of the respective section of the native blood vessel within the space formed between the inner and outer skirts for attaching the respective end of the vascular device to the respective section of the native blood vessel, wherein the inner skirt is configured to be attached to the respective section of the native blood vessel and the outer skirt is configured to be placed against an outer surface of the attachment between the inner skirt and the respective section of the native blood vessel, such that the respective section of the native blood vessel is disposed between the inner skirt and the outer skirt, and wherein the outer skirt is longer than the inner skirt.
