Inflatable medical devices
An inflatable balloon includes a base balloon having a cylindrical section and a conical section and at least one circumferential fiber extending circumferentially around the conical section. The inflatable balloon includes a plurality of reinforcing strips in the conical section over the at least one circumferential fiber. Each reinforcing strip includes a plurality of fibers extending at an angle relative to the at least one fiber. Each reinforcing strip is positioned a set circumferential distance away from a neighboring reinforcing strip.
1. An inflatable balloon comprising:
a balloon having a cylindrical section and a conical section;
a plurality of non-woven fibers extending along or around the conical section; and
a plurality of longitudinally extending reinforcing strips in the conical section over the plurality of non-woven fibers.
2. The inflatable balloon of claim 1 , wherein each reinforcing strip includes a plurality of fibers extending at an angle relative to the at least one fiber, and wherein each reinforcing strip is positioned a set circumferential distance away from a neighboring reinforcing strip.
3. The inflatable balloon of claim 2 , wherein the angle between the plurality of fibers of the reinforcing strip and the at least one fiber is approximately 90 degrees.
4. The inflatable balloon of claim 2 , wherein the plurality of fibers of the reinforcing strip extend substantially parallel to a longitudinal axis of the balloon.
5. The inflatable balloon of claim 1 , wherein the at least one fiber is a circumferential fiber, and further comprising a plurality of longitudinal fibers extending at an angle to the at least one circumferential fiber, wherein the at least one circumferential fiber extends over the plurality of longitudinal fibers.
6. The inflatable balloon of claim 5 , wherein the angle between the plurality of longitudinal fibers and the at least one circumferential fiber is approximately 90 degrees.
7. The inflatable balloon of claim 5 , wherein the plurality of longitudinal fibers extend substantially parallel to the longitudinal axis of the balloon.
8. The inflatable balloon of claim 1 , wherein each of the reinforcing strips comprises a fiber tape.
9. The inflatable balloon of claim 1 , wherein the reinforcing strips are arranged to radiate from an end of the balloon towards a central portion of the balloon.
10. The inflatable balloon of claim 1 , wherein each reinforcing strip includes only a single layer in a radial direction.
11. The inflatable balloon of claim 1 , wherein each reinforcing strip includes a tapered region.
12. The inflatable balloon of claim 1 , wherein the balloon includes a cylindrical end section, the conical section located between the cylindrical end section and the cylindrical section.

16. An inflatable balloon comprising:
a balloon having a cylindrical section and a conical section;
at least one fiber on the conical section; and
at least one reinforcing strip in the conical section extending longitudinally over the at least one fiber, the reinforcing strip extending only along the conical section of the balloon.
17. The inflatable balloon of claim 16 , wherein the at least one fiber is a circumferential fiber, and further comprising a plurality of longitudinal fibers extending at an angle to the at least one circumferential fiber, wherein the at least one circumferential fiber extends over the plurality of longitudinal fibers.
18. An inflatable balloon comprising:
a balloon having a cylindrical section and a conical section;
