Dual guide-wire medical device and method |
摘要 |
Methods and apparatus are provided for inserting a moveable device into a channel such as a vein or artery. The apparatus comprises first and second guide-wires joined by multiple breakable bonds for initially retaining portions of the guide-wires in substantially fixed mutual relationship, the multiple bonds breaking as the moveable device advances along the guide wires. The method comprises inserting the dual guide-wire assembly in the channel with the dual guide-wires initially in fixed relationship to each other and separating the guide-wires by advancing the moveable device along the dual guide-wire assembly sequentially breaking the multiple bonds joining the guide-wires. When the last bond between the wires is broken, the distal tips of the guide-wires are released. The arrangement is especially useful for placing dilation balloons with (or without) stents in bifurcated blood vessels. |
