Embodiment Construction

[0140] Vascular graft

[0141] refer to figure 1 , showing vascular graft 2. Vascular graft 2 includes a first graft anchor 4 at one end and a second graft anchor 6 at the other end. The first graft anchor 4 is longitudinally spaced from the second graft anchor 6 . The covering 10 extends along substantially the entire length of the vascular graft 2, thereby covering substantially all of the outer surfaces of the first graft anchor 4 and the second graft anchor 6. Alternatively, at least a portion of the first graft anchor 4 and / or the second graft anchor 6 (such as the ends of the graft anchors 4 , 6 ) may not be covered by the covering 10 . Alternatively, more than one covering 10 is used, such that the covering 10 may have multiple layers, or may include two or more overlapping sections along the length of the vascular graft 2 . Cover 10 may be made of any suitable material or materials, such as, but not limited to, polytetrafluoroethylene (PTFE).

Abstract

A vascular graft deployment tool may include: a handle; an elongate mandrel positioned distal of the handle; a vascular graft coaxially disposed at least partially around the mandrel; a sheath assembly comprising a distal sheath portion and a proximal sheath portion, where the distal sheath portion and the proximal sheath portion are configured to constrain a vascular graft against the mandrel at an insertion diameter; and an actuator movable relative to the handle and engaging the sheath assembly wherein operation of the actuator longitudinally separates at least one of the distal sheath portion and the proximal sheath portion to free at least a portion of the vascular graft. Further, the vascular graft is expandable from an inserted state to a deployed state, and at least two suture envelopes are located between opposite ends of the vascular graft.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This patent application claims priority to US Provisional Patent Application No. 62 / 906,041, filed September 25, 2019, which is incorporated herein by reference in its entirety and for all purposes. technical field [0003] The present invention generally relates to vascular and aortic grafts, and deployment tools for such grafts. Background technique [0004] The circulatory system includes the aorta and other large diameter vessels, as well as smaller diameter vessels and capillaries. Although diseases and other conditions affecting other blood vessels can be serious, diseases and other conditions affecting the aorta can be more serious and more likely to result in patient death due to the volume and pressure of blood pumped through the aorta. [0005] Complex thoracic aortic disease includes acute type A dissection (AAD) and chronic type A dissection (CAD), as well as aortic arch aneurysm (TAA), with or without inv...
