Benefits of technology

The patent describes devices and methods for treating blood vessel complications using an endovascular prosthesis with a hydrogel composition. The hydrogel composition is a non-expanded state and can expand to an expanded state after introduction into the target blood vessel. The prosthesis is designed to be delivered within a vasculature and to maintain its position within the blood vessel. The methods involve introducing the prosthesis into the target blood vessel and expanding it to the expanded state, where the hydrogel composition can mediate complications. The technical effect of this patent is to provide an improved method for treating blood vessel complications using an endovascular prosthesis with a hydrogel composition.

Problems solved by technology

When an endoleak occurs, it can cause continuous pressurization of the aneurysm sac and may result in an increased risk of rupture.

Embodiment Construction

[0020]Specific embodiments of the present technology are now described with reference to the figures, wherein like reference numbers indicate identical or functionally similar elements. Unless otherwise indicated, the terms “distal” and “proximal” are used in the following description with respect to the direction of blood flow from the heart and through the vasculature. Accordingly, with respect to a prosthesis or stent, the terms “proximal” and “distal” can refer to the location of portions of the device with respect to the direction of blood flow. For example, proximal can refer to an upstream position or a position of blood inflow, and distal can refer to a downstream position or a position of blood outflow. For example, “distal” or “distally” indicates an apparatus portion distant from, or a direction away from, the heart or along the vasculature in the direction of blood flow. Likewise, “proximal” and “proximally” indicates an apparatus portion near to, or in a direction towar...

Abstract

The present technology relates generally to endovascular prostheses. More particularly, the disclosure relates to endovascular prostheses having an outer surface of a graft material thereof associated with a hydrogel composition, which may swell upon implantation within a blood vessel, thereby mediating various complications associated with endovascular procedures. The hydrogel compositions can also include various stabilizing polymers and active agents to further aid their use in the body.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 352,626, filed Jun. 21, 2016, which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present technology relates generally to endovascular prostheses. More particularly, the disclosure relates to endovascular prostheses having an outer surface of a graft material thereof associated with a hydrogel composition, which may swell upon implantation within a blood vessel, thereby mediating various complications associated with endovascular procedures. The hydrogel compositions can also include various stabilizing polymers and active agents to further aid their use in the body.BACKGROUND OF THE INVENTION[0003]Endovascular procedures have been successfully used to treat thoracic and abdominal aneurysms. Such procedures typically require intravascular delivery of a stent graft to the site of the aneurysm. The graft is then expanded or deploy...
