Non-occluding dilation device
First Claim
1. A device for dilating a vessel or a structure positioned within a vessel, the device comprising a plurality of wires that are spaced apart when the device is dilated to allow for passage of fluid through the device, the device being sufficiently compliant so that when placed into a vessel and dilated it can conform to at least one diameter disparity ratio of between about 1.2:

Abstract
An assembly including a device for dilating a vessel or a structure (such as a stent or stent graft) within a vessel wherein the device comprises a plurality of wires that are spaced apart when the device is dilated so as to allow fluid to flow through the device. Thus, when in use the device does not occlude or substantially hinder the flow of blood through a vessel or into side vessels. The device may also be flexible enough to be easily maneuvered through tight bends in a vessel and/or be able to conform to varying diameters within a single vessel or within multiple vessels.

127. An assembly including a device for dilating a structure within a vessel, the device comprising a wire mesh body and including:
-
a length of between about 4 cm and about 15 cm;
a collapsed diameter of between about 10 and about 16 french;
a fully dilated diameter of between about 35 and about 55 mm;
wires of between about 0.008″ and
