摘要：
Non-occlusive modeling catheters including a dilation device for expanding an endoprosthesis implanted in a vessel are disclosed. In an embodiment, a modeling catheter includes a device comprising a plurality of compliant wires braided in a double overlapping pattern and having a length spanning between a proximal end of the device and a distal end of the device, wherein the device is positioned in at least a portion of an endoprosthesis implanted in a vessel, wherein, when the device is in a relaxed state, a plurality of spaces are formed between the plurality of wires to allow fluid to move freely through the plurality of spaces, and wherein, when the device is in a dilated state, the plurality of wires are sufficiently designed to exert a radial force on the endoprosthesis while continually allowing the fluid to move freely through the plurality of spaces.
