Problems solved by technology

Percutaneous transcatheter delivery of implant devices to accommodate various vascular sites and unique or lesioned anatomy suffers from an oversized delivery profile in the radially compressed state of the device
However, further reductions in the device and the corresponding reduction in the delivery profile of the delivery catheter can affect the radial strength of the implanted device during placement

Embodiment approach

[0068] can be improved as described above and in Figure 2-9 The components / features of the endoluminal prosthetic device shown in are described to form other embodiments arranged in accordance with the present technology. For example, figure 2 The integral support structure 116 of the illustrated prosthesis 100 may include a channel 118 formed between the inner and outer layers of the wall (eg, Figure 3A shown) and the channel 418 formed between the outer surface of the wall and the encapsulating material to which it is attached (as shown in Figure 4A combination shown). Likewise, as previously stated and as figure 2 and 4A The endoluminal prosthetic device shown in -B is shown having flanges on the outer surface of the tubular body wall with only a fluid-absorbent component located therein, the endoluminal prosthetic device may also have wires (e.g. Figure 5A shown in ) or other structures placed within it. The various other embodiments described herein may also b...

Abstract

Endoluminal prosthetic devices having fluid-absorbable compositions for repair of vascular tissue defects, such as an aneurysm or dissection, are disclosed herein. A prosthesis for repairing an opening or cavity within a target vessel region configured in accordance herewith includes a tubular body sized to substantially cover the opening or cavity, and having channels formed in a wall thereof. The channels can include a fluid-absorbable composition deposited therein and which is configured to absorb fluid (e.g., blood) and swell within the channels, thereby providing radial expansion of the tubular body in situ.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application Serial No. 62 / 316,395, filed March 31, 2016, which is incorporated herein by reference in its entirety. field of invention [0003] The present technology generally relates to endoluminal prosthetic devices for repairing vascular tissue defects. In particular, various embodiments relate to systems and devices for treating / manipulating vascular defects in a patient's aorta, such as aneurysms, arterial dissections, penetrating ulcers, and / or transections hurt. Background technique [0004] Tissue defects in blood vessels, such as aneurysms (eg, aortic aneurysms) or arterial dissections, can, for example, lead to pain (eg, abdominal and back pain), stroke and / or eventual rupture of the blood vessel. An aneurysm occurs when the vessel wall becomes weak, causing the vessel wall to widen, open, or form a cavity in it. The opening of this cavity can be further deteriorated...
