ABSTRACT:
An inflatable angioplasty balloon is formed in an unstressed configuration for inflation into an expanded configuration and deflation into a collapsed configuration. The balloon has a body portion and two hollow end portions, with the end portions being attached to opposite ends of the body portion.
In the balloon's unstressed configuration, the body portion has three flat folding regions extending the length of the body portion. Successive folding regions are separated from each other by curved reinforcing regions. The end portions are configured and oriented to guide the folding regions of the balloon into a pleated, collapsed configuration when the interior of the balloon is evacuated.
