Abstract: The present invention provides an implantable graft that includes an elongate graft tube having opposing ends defining an attachment site for attaching the graft to a stent. The graft further includes a reinforcement member attached adjacent to at least one of the ends of the graft for establishing a reinforced attachment site for the graft, thereby preventing elongation of a suture hole in the material. Furthermore, the present invention provides a graft wherein at least one end of the graft is folded over itself and glued or sutured to itself and/or the stent, thereby forming a reinforcement thereto.

Abstract: A composite medical device includes a knitted structure having a single layer of yarns to define a single layered wall, where the yarns are interlaced into stitches in a knit pattern capable of resilient longitudinal elongation and resilient radial contraction of the knit from a quiescent state to an elongated state, and a layer of ePTFE securably attached to the knitted structure. The knit pattern is a warp knitted pattern of yarns forming a textile layer having an interior surface and an exterior surface, where interior yarns form the interior surface and form loops in the longitudinal direction of said knitted structure, and exterior yarns form the exterior surface and are diagonally shifted over two or more of the interior yarns in an alternating pattern along a width of the knitted structure before engaging an the interior yarn.

Abstract: A method for providing dilation resistance to an implantable tubular graft includes the steps of (a) providing a graft having opposed open ends and a textile wall extending in a lengthwise direction therebetween defining a graft diameter, wherein the textile wall has radially extending yarns having a radial extent which inter-engage longitudinally extending yarns having a longitudinal extent to define a textile pattern and further wherein the radially extending yarns are obliquely oriented to the lengthwise direction of the graft, thereby defining a first acute angle from the lengthwise direction of the graft; (b) providing an elongate tubular mandrel having a diameter which differs from the graft diameter by a factor of at least 1.

Abstract: A radially expandable stent-graft endoprosthesis is provided. The graft included in the stent-graft is a knitted tubular structure circumferentially disposed and securably attached to the stent. The knitted tubular structure has a warp knit pattern of interlacing yarns with at least a two-needle underlap to provide greater than 150 percent longitudinal stretchability while substantially inhibiting dilation. A knitted tubular graft and a knitted medical fabric with greater than 150 percent longitudinal stretchability are also provided.

Abstract: A radially expandable stent-graft endoprosthesis includes a knitted tubular structure circumferentially disposed and securably attached to the stent. The knitted tubular structure has a warp knit pattern of interlacing yarns with at least a two-needle underlap to provide greater than 50 percent longitudinal stretchability while substantially inhibiting dilation. A knitted tubular graft is combined with an ePTFE liner to form a composite with greater than 50 percent longitudinal stretchability is also provided. The knitted tubular graft also has a warp knit pattern of interlacing yarns with at least a two-needle underlap to provide the longitudinal stretchability while also substantially inhibiting dilation.

Abstract: A radially expandable stent-graft endoprosthesis is provided. The graft included in the stent-graft is a knitted tubular structure circumferentially disposed and securably attached to the stent. The knitted tubular structure has a knit pattern of interlacing yarns in an Atlas or a modified-Atlas pattern to provide greater than 150 percent longitudinal stretchability. A knitted tubular graft and a knitted medical fabric with greater than 150 percent longitudinal stretchability are also provided.
