Abstract
A joint and method for producing a joint in an endovascular graft. In one embodiment, a flap of a flexible material portion of an endovascular graft is folded about a portion of an expandable member to form a loop portion. The flap is secured in the loop configuration so that tensile force on the expandable member is transferred into a shear force on the fixed portion of the flap.
Claims7
An endovascular graft or section thereof comprising:
- a generally tubular flexible material portion comprising a plurality of layers;
- and
- a serpentine expandable member circumferentially oriented about a circumference of the generally tubular flexible material portion, wherein the expandable member is secured to the generally tubular flexible material portion with a joint that includes at least one flap of the flexible material portion folded back to form a loop portion about the serpentine expandable member, wherein the flap of flexible material comprises a layer that is secured to itself and another layer, and further wherein two adjacent layers are selectively attached to each other to form an inflatable channel between the two adjacent layers.
An endovascular graft or section thereof comprising:
- a multi-layered flexible material portion that comprises at least two layers;
- an inflatable channel formed between two layers of the flexible material portion;
- an expandable member positioned at or adjacent an end of the flexible material portion,
- wherein the expandable member is secured to at least one layer of the flexible material portion with a joint that includes at least one flap of the flexible material folded back to form a loop portion about the expandable member, wherein the flap of flexible material comprises a layer that is secured to itself and another layer.
