Patent Images
1. An inflatable balloon for medical use comprising at least two helically wrapped layers formed into a wrapped balloon with a sealed region at least partially radially surrounded by an inflatable region, and an inflation means;
- wherein the sealed region is formed from the wrapped layers, extends along a length in a radial dimension, does not inflate, and is adjacent to an opening traversing an open region passing through the balloon in an inflated state.

45. A method of controlling the flow through a vessel comprising the steps of positioning a toroidal-shaped balloon in a desired location in a vessel, wherein said toroidal-shaped balloon comprises at least two helically wrapped layers formed into the toroidal-shaped balloon with a sealed region formed from the wrapped layers and at an inner diameter of the balloon and extending along a length in a radial dimension, wherein the sealed region does not inflate and is at least partially radially surrounded by an inflatable region;
- and inflating the balloon to a desired pressure thereby reducing an open area and reducing the flow through the vessel.

48. A method of controlling the flow through a vessel comprising the steps of:
- positioning a toroidal-shaped balloon in a desired location in a vessel, wherein said toroidal-shaped balloon comprises at least two helically wrapped layers formed into the toroidal-shaped balloon with a sealed region formed from the wrapped layers and at an inner diameter of the balloon and extending along a length in a radial dimension, wherein the sealed region does not inflate and is at least partially radially surrounded by an inflatable region; and
inflating the balloon to a desired pressure thereby increasing a diameter of the vessel and increasing an open area and increasing flow through the vessel. - View Dependent Claims (49, 50)
