PROBLEM TO BE SOLVED: To provide vascular devices and methods for addressing aortic pathologies that facilitate hemostasis at the junctions of the ends of the vascular device with the native aorta or other vessels to minimize or eliminate the risk of endoleaks.SOLUTION: One or both ends of a vascular device 100 may include an inner skirt 140 and an outer skirt 150 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 vascular device, with sutures or the like. In engaging, the outer skirt is disposed such that the blood vessel is located between the inner and outer skirts. Devices and associated methods allow endografts to be deployed and engaged with an end of the vascular device in areas with sufficient landing zones.SELECTED DRAWING: Figure 3 |
