摘要: Methods and devices for molding a desired configuration into an endovascular graft section that is made of a plurality of layers of fusible material. Layers of fusible material are disposed on a shape forming mandrel with seams in the layers that may be configured to produce inflatable channels. The graft section and shape forming mandrel can be placed in a mold which constrains an outer layer or layers of fusible material while the inflatable channels are being expanded and the fusible material of the graft section fixed. In some embodiments, the fusible material of the graft section may be fixed by a sintering process.

摘要: A device and method for the manufacture of medical devices, specifically, endovascular grafts, or sections thereof. Layers of fusible material are disposed upon a shape forming member and seams formed between the layers in a configuration that can produce inflatable channels in desired portions of the graft. After creation of the seams, the fusible material of the inflatable channels may be fixed while the channels are in an expanded state. A five axis robotic seam forming apparatus may be used to create the seams in the layers of fusible material.
