Non-occlusive dilation devices

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 expand from a relaxed state to a dilated state,
• wherein the device is sufficiently designed to be positioned in at least a portion of an endoprosthesis implanted in a bifurcated vessel,
• wherein, when the device is in the relaxed state and positioned in the endoprosthesis, the overlapping pattern creates a plurality of spaces between the plurality of wires allowing fluid to move freely through the plurality of spaces,
• wherein, when the device is in the 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 multi-vessel diameter disparity ratio in the bifurcated vessel ranging from about 1:1 to 20:1.
