Abstract
This invention relates to the field of balloon catheters and more particularly to catheter balloons having controlled failure mechanisms for the prevention of catastrophic failure of the balloon during overpressure conditions.
Claims14
A method for axial release of inflation medium in a controlled pressure release balloon catheter at an intravascular site, comprising the steps of:
- introducing the controlled pressure release balloon catheter device into the vasculature, wherein said catheter has a longitudinal axis;
- advancing the controlled pressure release balloon catheter through the vasculature to an intravascular site, wherein said controlled pressure balloon has a longitudinal axis;
- expanding the balloon against the vessel wall;
- wherein in the event of excess pressure, releasing the inflation medium substantially longitudinally.
