| 20160120638 | Intralumenal Stent Graft Fixation - This document describes intralumenal stent graft devices with integrated anchor members that are selectively deployable in situ. The deployment of the anchor members is also reversible, to thereby facilitate retrieval of the stent graft device. These stent graft devices are well-suited for sealing and repairing defects in a body lumen wall. Such defects can include, but are not limited to, aneurysms and lumen wall openings. In some embodiments, the intralumenal stent graft devices provided herein are well-suited for use in the GI tract including the colon. That is the case because the integrated anchor members provide the stent graft devices with a high level of migration resistance, whereby the stent grafts can remain resiliently located in a desired position within the GI tract despite the peristaltic movements of the GI tract. | 05-05-2016 |
| 20160120667 | DEVICES AND METHODS FOR TREATING ANEURYSMS AND OTHER VASCULAR CONDITIONS - A fenestrated aortic cuff is configured to be delivered endovascularly to a target region, deployed, fastened, and sealed to a vessel wall, e.g., in a neck region of an aortic aneurysm. Example fenestrated cuffs provide a suitable landing zone for a commercially available endograft, which may be, in some cases, positioned below or above the renal arteries in order to complete exclusion of an abdominal aortic aneurysm (AAA) or a thoracic aortic aneurysm (TAA), respectively, from systematic circulation. In some cases, fenestrated cuff function is facilitated and improved by employing active fixation and sealing mechanisms, including, e.g., helical fasteners, which may allow deployment of the fenestrated cuff in short neck regions with limited sealing area. | 05-05-2016 |
