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.
Claims19
A method for securing a transversely oriented member to a flexible material portion of an endovascular graft or section thereof comprising:
- a) providing a first layer of flexible graft material;
- b) providing a flap of flexible graft material over a portion of the first layer;
- c) disposing the transversely oriented member in proximity to the flap;
- d) folding the flap over at least a portion of the transversely oriented member to form a looped portion of the flap about the transversely oriented member;
- e) securing the flap in the looped configuration;
- f) providing a second layer of flexible graft material;
- g) disposing the second layer over the flap and over at least a portion of the first layer;
- and
- h) securing the first and second layers to each other at a location distal from the flap to define a flexible material portion of an endovascular graft or section thereof.
