摘要： Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is “hybrid” in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.

摘要： The techniques of this disclosure generally relate to modular stent device and method of deploying the same. The method includes introducing a delivery system including the modular stent device via supra aortic access. The delivery system is advanced into the ascending aorta. Once positioned, the modular stent device is deployed from the delivery system such that an artery leg of the modular stent device engages the brachiocephalic artery and a bypass gate engages the aorta, wherein the artery leg partially collapses the bypass gate. The artery leg has a greater radial force than the bypass gate such that the artery leg remains un-collapsed and opened. Accordingly, blood flow through the artery leg and perfusion of the brachiocephalic artery and preservation of blood flow to cerebral territories including the brain is insured.

摘要： The techniques of this disclosure generally relate to a stent-graft system including a bifurcated stent-graft, a first bifurcating branch device, and a first branch extension. The bifurcated stent-graft includes a body, a first branch limb, and a second branch limb. The first bifurcating branch device includes a body segment coupled to the first branch limb of the bifurcated stent-graft, a first branch limb, and a second branch limb. The first branch extension is within the first branch limb of the first bifurcating branch device and within an external iliac artery. The first bifurcating branch device has a wide patient applicability since the treatment can be extended proximal to the anatomical iliac bifurcation and is not limited by the common iliac artery length. The stent-graft system is suitable to treat a wide range of internal and external iliac artery diameters.

摘要： The techniques of this disclosure generally relate to a modular stent device that is deployed into the ascending aorta via femoral access. The modular stent device is a base or anchor component to which additional modular stent devices can be attached to exclude diseased areas of the aorta while at the same time allowing perfusion of the brachiocephalic artery, the left common carotid artery, and/or the left subclavian artery.

摘要： The techniques of this disclosure generally relate to prosthesis formed from a biodegradable composite yarn. The biodegradable composite yarn includes a permanent core and a biodegradable shell. The biodegradable shell slowly dissolves over a period of time when placed in a vessel. As the biodegradable shell dissolves, openings are created in the prosthesis that are filled with tissue from the vessel wall of the vessel. The integration of the tissue into the prosthesis provides biological fixation of prosthesis in the vessel and prevents endoleaks and migration of prosthesis.

摘要： The present technology relates generally to endovascular prostheses. More particularly, the disclosure relates to endovascular prostheses having a graft material and a stent structure attached with a suture, or a seam formed by a suture, where the suture has a coating that expands upon exposure to body fluids. The expansion allows for the coating to fill suture holes in the graft material so as to reduce or eliminate endoleaks.

摘要： A stent-graft prosthesis includes a generally tubular outer PTFE layer, a generally tubular helical stent, a generally tubular inner PTFE layer, and a suture or fabric support strip. The outer PTFE layer defines an outer layer lumen. The helical stent is disposed within the outer layer lumen and defines a stent lumen. The inner PTFE layer is disposed within the stent lumen and defines an inner layer lumen. The suture includes a suture first end coupled to a stent first end and a suture second end coupled to a stent second end, with the suture disposed between the outer PTFE layer and the inner PTFE layer. Alternatively, the fabric support strip is disposed between the outer and inner PTFE layers. The suture or fabric support strip may include a plurality of sutures or fabric support strips and may be spaced equally around a circumference of the inner PTFE layer.

摘要： 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.
