Endovascular aneurysm devices, systems, and methods
First Claim
1. A seal assembly for an endovascular device, the seal assembly comprising:
- a first seal component comprising a center post and a collar that extends radially from an end of the center post, wherein the collar comprises at least one guide tube formed therethrough, the at least one guide tube being radially outward of the center post;
a second seal component with at least one guide tube formed therethrough, the second seal component registering with the first seal component with the at least one guide tube in the second component coaxially aligned with the at least one guide tube in the first component; and
a septum sandwiched between the first and second seal components, the septum accommodating passage of a control filament from one of the coaxially aligned guide tubes, through the septum, to the other one of the coaxially aligned guide tubes, thereby providing a fluid seal for the control filament, the center post of the first seal component passing through the septum.

Abstract
Devices, systems, and methods for implanting prostheses in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.

15. An endovascular apparatus comprising:
-
a catheter assembly including an operative element that, in use, is exposed to a body fluid; a control element; a control filament coupled at one end to the control element and at an opposite end to the operative element; and a seal assembly between the control element and the operative element through which the control filament passes to prevent contact between the body fluid and the control element, the seal assembly comprising; a first seal component comprising a center post and a collar that extends radially from an end of the center post, wherein the collar comprises at least one guide tube formed therethrough, the at least one guide tube being radially outward of the center post; a second seal component with at least one guide tube formed therethrough, the second seal component registering with the first seal component with the at least one guide tube in the second component coaxially aligned with the at least one guide tube in the first component; and a septum sandwiched between the first and second seal components, the septum accommodating passage of the control filament from one of the coaxially aligned guide tubes, through the septum, to the other one of the coaxially aligned guide tubes, thereby providing a fluid seal for the control filament, the center post of the first seal component passing through the septum. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
