1. A balloon catheter system having an integrated inflation subsystem, comprising:

  • a manifold having internal passages;

    a sealed pressurized vessel permanently attached to an inflation port in the manifold, wherein the pressurized vessel is attached to the manifold in a manner selected from the group consisting of adhesion and thermal welding;

    a sealed vacuum vessel permanently attached to a vacuum port in the manifold in a manner selected from the group consisting of adhesion and thermal welding;

    a balloon catheter having a balloon on a distal end in fluid communication with an inflation lumen extending through the catheter;

    a balloon port in the manifold in fluid communication with and permanently connected to the balloon catheter inflation lumen, wherein the manifold with connected vessels is assembled and packaged with the balloon catheter; and

    a control valve on the manifold configured to selectively open and close fluid communication between the balloon port and the inflation port so that a positive pressure differential from the pressurized vessel inflates the balloon, wherein the control valve is also configured to selectively open and close fluid communication between the balloon port and the vacuum port so that a negative pressure differential from the vacuum vessel deflates the balloon.
