Abstract: Disclosed is a stent graft, including a graft body, a sealing stent at the proximal end of the graft body and completely overlapped by the graft body, and a diameter reducing loop arrangement. The sealing stent includes proximal apices at a proximal end thereof and distal apices at a distal end thereof. The diameter reducing loop arrangement includes a loop element. The loop element includes a first end, a second end, and a strand section from the first end to the second end. The first end is attached to the distal end of the sealing stent. The loop element is configured to pass circumferentially around the distal end of the sealing stent and have a release wire pass through a loop at the second end. The diameter reducing loop arrangement is configured to constrict the distal apices of the sealing stent and cause the sealing stent to adopt a substantially conical or frustoconical shape.

Abstract: An endoluminal graft includes a tubular graft material having a closed sleeve integral with the tubular graft material. The closed sleeve extends a distance along the tubular graft material. A length of wire extends at least partially along the distance and is enclosed by the sleeve. The tubular graft material and the sleeve may comprise a single piece of graft material. The sleeve may be a closed circumferential sleeve and/or a closed longitudinal sleeve.

Abstract: A stent graft for deployment in a curved lumen such as the aortic or thoracic arch comprises a constraining mechanism at its proximal end. A stent provided at the proximal end of the stent graft includes loops of material that co-operate with restraining wires that extend between a central guide wire carrier and a restraining wire cannula. The constraining mechanism maintains the proximal stent constrained at both of its proximal and distal ends. The proximal stent can then expand after expansion of the remainder of the stent graft during deployment. In an embodiment, the constraining mechanism acts to constrain two adjacent struts of the proximal stent at three points radially therearound, at the proximal end of the stent and at the distal end of the stent. The proximal stent may then overlap with the interior of an adjacent stent at an inner part of a curved vessel.

Abstract: A handle assembly for a delivery device the sequential release of trigger wires from a prosthesis to release the prosthesis from the delivery device. The handle assembly has two handles, one of which is a rotating handle. The rotating handle has a first and second trigger wire release mechanisms which operate to sequentially release a first and second trigger wire, respectively, and a locking mechanism. The other handle has a locking mechanism that prevents that operation of the second trigger wire release mechanism until the first trigger wire has been released.

Abstract: A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. The indwelling guide wire are configured to receive the access sheaths. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate cathertization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

Abstract: A vascular occluder includes a tubular support element and a sleeve of occluding material disposed within the support element. The sleeve is twisted in the support creating a constriction which closes the lumen of the sleeve. The lumen of the sleeve can nevertheless be opened by a guide wire or cannula for over the wire delivery. Once the guide wire or cannula are withdrawn from the sleeve, the sleeve will close again by the action of blood pressure thereon. Blood pressure will act to maintain closing pressure on the sleeve, thereby avoiding or reducing the risk of recanalization.

Abstract: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.

Abstract: The present embodiments describe a graft material suitable for use in a medical procedure. In one example, the graft material comprises a plurality of circumferential threads and achieves at least two unique physical states. Each thread is constructed such that during a first state, the threads are taut, inexpansible, and have a first diameter. Each thread is also constructed such that during a second state occurring after the first state, the threads are taut, inexpansible, and have a second diameter greater than the first diameter. The first and second diameters are predetermined. In another example, at least one thread is constructed from at least two interwoven fibers, at least one of which is biodegradable. Over time, at least one fiber biodegrades, allowing the remaining fiber(s) to elongate, thereby achieving the second inexpansible state having a greater diameter.

Abstract: An aortic graft device (10) is provided with a graft portion (12) integrally fixed to a corrugated trunk portion (14). A fixing ring (16) is provided between the graft and trunk portions. The trunk portion (14) can be everted into the graft portion, leaving the fixing ring (16) at an extremity of the device for suturing purposes. The fixing ring (16) is preferably made from a relatively stiff material such as a compressed foam or rubber like material, which provides a relatively solid component for a surgeon to hold during suturing and which can provide a strong support for sutures.
