摘要：
Inflation devices and methods for using them are provided for selectively inflating and deflating multiple balloons on a catheter. For example, the inflation device may include a first valve including a plurality of first valve ports and a first valve member movable between multiple positions for opening and closing fluid paths between the first valve ports, a second valve including a plurality of second valve ports and a second valve member movable between multiple positions for opening and closing fluid paths between the second valve ports, and an actuator coupled to the first and second valve members for directing the first and second valve members between multiple positions, e.g., to selectively pull vacuum and sequentially inflate the balloons.
