<p>A device and method for the manufacture of medical devices, specifically, endovascular grafts (16), or sections thereof. Layers of fusible material (13) are disposed upon a shape forming member (14) and seams (81) formed between the layers in a configuration that can produce inflatable channels (82) in desired portions of the graft. After creation of the seams (81), the fusible material of the inflatable channels may be fixed in a mold (90) to constrain an outer layer or layers of fusible material while the channels (82) are being expanded. A joint (330) may be produced on the endovascular graft by folding a flap (333) of a flexible material portion of an endovascular graft about a portion of an expandable member (314) to form a loop portion (348). The flap (333) may be secured in the loop configuration (348) so that tensile force on the expandable member (314) is transferred into a shear force on the fixed portion of the flap.</p> |
