Abstract: A composite biomaterial having a continuous metal sheet with arcuate members that define a first fenestration pattern, and a polymer layer over at least one surface of the continuous metal sheet. The arcuate members elastically stretch to allow the continuous metal sheet to bend in more than one axis without buckling or wrinkling.

Abstract: The present disclosure relates generally to devices, systems, and methods for use with tissue, more particularly the present disclosure relates to a device including a frame with a surface defining a pinch point region with a predefined shape. The device also includes a tab with an opening defining an anchor attachment on the frame. The frame can elastically deform under a stress to alter the predefined shape of the pinch point region.

Abstract: A method for deployment of a multi-part endoluminal device includes deploying a first portion of the device sequentially from its distal end to its proximal end, then deploying a second portion of the device sequentially from its proximal end to its distal end so that its distal end overlaps the first portion proximal end. The system for deploying the endoluminal device includes a first introducer loaded with a first endoluminal device and adapted to deploy the first device sequentially from the distal end to the proximal end, and a second introducer loaded with a second endoluminal device and adapted to anchor the second endoluminal device proximal end while deploying the second endoluminal device sequentially from the proximal end to the distal end.

Abstract: A multi-section filamentary stent comprises a braided section, which is a cylindrical mesh of a first set of filaments, connected to at least one wound section comprising a second set of one or more filaments having a repeating configuration with a bent portion. The two sections are preferably connected by at least one continuous filament extending into both sections. The two sections may be connected by a weld, a suture, a common graft, an overlapping portion of the two sections, or one or more filaments of one section looping through portions of the other section. The stent may comprise a first section, having a braided first stent architecture with a first flexibility and a first radial force, and a second section, having a non-braided second stent architecture with a second flexibility less than the first flexibility and a second radial force greater than the first radial force, in which at least one continuous filament is integral to both the first and second sections.

Abstract: An introducer deploys an endoluminal device in a distal location from a proximal location. The introducer comprises a retrograde portion, an anterograde portion axially moveable relative to the retrograde portion, a shaft having a distal tip and an anterograde sheath attached to the distal tip, and anchoring means in at least one of the retrograde portion or the anterograde portion for anchoring the device during deployment from its proximal end to its distal end. An inner sheath may be mounted concentrically over the shaft with the endoluminal device mounted concentrically over the inner sheath. The anchoring device may comprise an inflatable balloon mounted radially inside the retrograde portion, a tether, or an extended portion of the endoluminal device confined by a notch in the interface of two sheaths in the retrograde portion of the introducer, or may comprise a holder in the anterograde portion.

Abstract: A bifurcated, braided stent has a body that branches into a plurality of legs and is adapted for deployment in a lumen. At least a portion of each leg of the stent comprises a discrete plurality of continuous filaments braided together, and at least a portion of the body comprises one or more of the continuous filaments from each of the legs braided together. The stent can be used for treating a diseased bifurcated lumen of a human being by deploying the stent therein. The stent can be constructed by a process comprising braiding each plurality of filaments to form the leg sections, and braiding one or more filaments from each plurality of filaments together to form the body. The process may be performed by creating the legs first and then the body, or vice versa. The stent may be constructed on a mandrel using a braiding machine.

Abstract: A system and method employs collar stents to implant an endoluminal device, such as a stent-graft, in a lumen. The system comprises at least one collar stent adapted to precondition a portion of the lumen for anchoring an endoluminal device having at least a portion adapted to be deployed radially within the collar stent. The method comprises first deploying one or more collar stents, and then deploying the endoluminal device radially within the one or more collar stents. In various embodiments, the collar stent may be radiopaque, may have inwardly protruding barbs for engaging the endoluminal device, and may have a region having a relatively low percentage of open area for bridging a portion of the main lumen having an intersecting lumen. The preconditioning step of implanting the collar stent may change the morphology of the lumen to more favorable morphology, such as from a non-circumferential geometry to a circumferential geometry.
