Abstract

A medical balloon with a variable diameter that is reinforced with continuous fibers woven to form a fabric with a varying number of layers and fiber densities. Portions of the balloon having a relatively smaller diameter are reinforced with a fabric having a reduced fiber density and an increased number of layers to facilitate the placement of the layers. The fabric also includes a braiding pattern that facilitates the transition from a single layer fabric to a multiple layer fabric. Also described is a manufacturing method for the braiding and layering.

First claim

The invention claimed is:

1. A medical balloon, comprising:
a main fabric having a main braid pattern of interweaved first and second fibers that reinforce the balloon;
a first fabric having a first braid pattern of the first fibers, the first fabric separating into an inner first fabric and an outer first fabric to reinforce an end portion of the balloon; and
a second fabric at least partially overlying the first fabric, said second fabric having a second braid pattern of the second fibers,
the first and second fibers joining the main fabric to the first and second fabrics.

2. The medical balloon of claim 1 , the second fabric separating into an inner second fabric and an outer second fabric to reinforce the balloon.

3. The medical balloon of claim 1 , a main portion of the balloon defining a cylinder, and first and second portions of the balloon defining cones.

4. The medical balloon of claim 1 , the main fabric joining the first and second fabrics proximate to a transition between a cylindrical portion of the balloon and a cone section of the balloon.

5. A medical balloon, comprising:
a main fabric having a main braid pattern of interweaved first and second fibers that reinforce the balloon;
a first fabric having a first braid pattern of the first fibers; and
a second fabric having a second braid pattern of the second fibers;
the first and second fibers joining the main fabric to the first and second fabrics; and
the first fabric separating into an inner first fabric and an outer first fabric to reinforce an end portion of the balloon.

6. The medical balloon of claim 5 , the second fabric separating into an inner second fabric and an outer second fabric to reinforce the balloon.

7. The medical balloon of claim 5 , a main portion of the balloon defining a cylinder, and first and second portions of the balloon defining cones.

8. The medical balloon of claim 5 , the main fabric joining the first and second fabrics proximate to a transition between a cylindrical portion of the balloon and a cone section of the balloon.

9. A medical balloon, comprising:
a main fabric having a main braid pattern of interweaved first and second fibers that reinforce the balloon;
a first fabric having a first braid pattern of the first fibers; and
a second fabric having a second braid pattern of the second fibers;
the first and second fibers joining the main fabric to the first and second fabrics; and
the second fabric separating into an inner second fabric and an outer second fabric to reinforce the balloon.

10. The medical balloon of claim 9 , the first fabric separating into an inner first fabric and an outer first fabric to reinforce an end portion of the balloon.

11. The medical balloon of claim 9 , a main portion of the balloon defining a cylinder, and first and second portions of the balloon defining cones.

12. The medical balloon of claim 9 , the main fabric joining the first and second fabrics proximate to a transition between a cylindrical portion of the balloon and a cone section of the balloon.

13. A medical balloon, comprising:
a main fabric having a main braid pattern of interweaved first and second fibers that reinforce the balloon along a first longitudinal portion of the balloon;
a first fabric having a first braid pattern of the first fibers along a second longitudinal portion of the balloon; and
a second fabric having a second braid pattern of the second fibers along the second longitudinal portion of the balloon, such that the second fabric both radially overlies and circumferentially surrounds the first fabric along the second longitudinal portion of the balloon,
the first and second fibers joining the main fabric to the first and second fabrics.

14. The medical balloon of claim 13 , the first fabric separating into an inner first fabric and an outer first fabric to reinforce an end portion of the balloon.

15. The medical balloon of claim 13 , the second fabric separating into an inner second fabric and an outer second fabric to reinforce the balloon.

16. The medical balloon of claim 13 , wherein the first longitudinal portion of the balloon defines a cylinder, and the second longitudinal portion of the balloon defines a cone.

17. The medical balloon of claim 13 , the main fabric joining the first and second fabrics proximate to a transition between a cylindrical portion of the balloon and a cone section of the balloon.
