  • Patent number: 10335266
    Abstract: A stent device includes a first graft member, a second graft member and a stent frame defining a central axis. The frame has an abluminal surface engaged with the first graft member and a luminal surface engaged with the second graft member such that the first graft member and the second graft member encapsulates the stent frame along the length of the central axis. The stent frame includes a configuration where the stent frame is disposed on a curvature such that the abluminal surface has a radius of curvature of approximately 20 millimeters about a center of the curvature and the luminal surface defines a substantially constant effective cross-sectional area at any portion generally transverse to the central axis of the stent frame disposed about the curvature.

  • Patent number: 10265202
    Abstract: The present disclosure relates to an endoluminal prosthesis, such as a stent graft that includes one or more fenestrations to accommodate endovascular disease, such as an aneurysm in cases where one or more side branches is involved. In one aspect, the prosthesis includes fenestrations that are pivotable to accommodate the dynamic geometry of the aortic branches. In another aspect, the pivotable fenestrations include a first perimeter, a band of flexible material attached and surrounding the first perimeter, a second perimeter attached to and surrounding the band of flexible material and a support frame disposed about a surface of the band of flexible material. The first perimeter, band of flexible material, and second perimeter have a geometric shape. The support frame includes a plurality of support units having curved segments. The curved segments of the support units may be concave with respect to an exterior surface of the prosthesis.

  • Patent number: 10251743
    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. Indwelling access sheaths are provided within auxiliary lumens of a pusher catheter and dilators are preloaded into the access sheaths along with the indwelling guide wire. 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 cathertisation of a side branch or target vessel through the fenestration or be used to stabilise the access sheath during catheterisation, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

  • Patent number: 10231822
    Abstract: A stent graft for placement in the thoracic arch of a patient has a tubular body defining a main lumen therethrough, a plurality of zig zag stents along the tubular body, each of the stents comprising a plurality of struts and bends, the bends being between adjacent struts. At least a first stent and an adjacent second stent having at least a pair of adjacent bends on the first stent aligned with an adjacent pair of bends on the second stent, whereby a first pair of adjacent struts of the first stent and a second pair of adjacent struts of the second adjacent stent together define a diamond shape region. A recess is within the diamond shaped region with the recess extending into the lumen of the tubular body. A fenestration extending into the tubular body within the recess in the diamond shaped region and a graft tube leading from the fenestration into the main lumen. There can be one, two or three diamond shaped regions, recesses, fenestrations and graft tubes.

  • Patent number: 10231821
    Abstract: A composite hollow lumen and a method for producing the lumen are provided. The lumen includes a tubular textile formed of yarns having a first tensile strength and a matrix material in which the tubular textile is embedded to form a conduit having a bore and a sidewall substantially impermeable to liquid. The matrix material has a second tensile strength that is lower than the first tensile strength. The method for producing a composite lumen includes selecting yarns having a first tensile strength, selecting an elastomeric matrix material having a second tensile strength that is lower that the first tensile strength, forming a tubular textile of the yarns, and embedding the tubular textile in the matrix material to form a conduit having a bore and conduit walls that are substantially impermeable to liquid. The elastomeric matrix material is a biodegradable or bioresorbable polyester.

  • Patent number: 10219891
    Abstract: A stent-graft prosthesis includes a tubular graft and a stent coupled to the tubular graft via a plurality of stitches. The stent has a sinusoidal pattern defined by a plurality of crowns and a plurality of struts. The stitches form a stitch path having a sinusoidal pattern that corresponds to the sinusoidal pattern of the stent. A width of curved segments of the stitch path that are disposed over crowns of the stent is configured to permit relative longitudinal movement between the stents and the tubular graft. A width of intermediate segments of the stitch path that are disposed over struts of the stent may be configured to restrict or permit relative circumferential movement between the stents and the tubular graft. The stitch path may include a plurality of transverse stitches in order to prevent exposure of the crowns beyond the stitch path.
