Abstract:
1. A device comprising: 48 round nitinol wires braided in a double overlapping pattern, wherein each of the wires has a diameter of about 0.28 mm and a length between about 10 cm and about 15 cm spanning between a proximal end of the device and a distal end of the device, wherein a braid density of the wires is about 7 ppi, wherein the device is sufficiently designed to be positioned in at least a portion of an endoprosthesis implanted in a single vessel, wherein, when the device is in a relaxed state and positioned in the endoprosthesis, a plurality of spaces are formed between the plurality of wires to allow fluid to move freely through the plurality of spaces, wherein, when the device is in a dilated state and positioned in the endoprosthesis, 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, and wherein, when the device is in the dilated state and positioned in the endoprosthesis, the plurality of wires are sufficiently designed to conform to a diameter disparity ratio in the single vessel ranging from about 1:1 to about 10:1.
