Abstract
A composite medical balloon includes a base balloon with first and second tapered portions (108) and a barrel portion (106) therebetween. The base balloon includes one or more fiber layers. A hybrid layer is applied over the base balloon, such as over the fiber layer. The hybrid layer includes a tube (70) for covering the barrel portion (106) and a spiral wrapping (80) for covering one or both of the first and second tapered portions (108). Related methods of forming of such a balloon are also disclosed.

A composite medical balloon, comprising:
- a base balloon layer including first and second tapered portions and a barrel portion therebetween, the base balloon defining a first balloon length extending from a longitudinal location within the first tapered portion to a longitudinal location within the second tapered portion;
- and
- a hybrid layer over the base balloon layer, the hybrid layer comprising a seamless tube covering the barrel portion and a spiral wrapping covering at least one of the first and second tapered portions;
- wherein neither the seamless tube nor the spiral wrapping extends an entire length of the first balloon length.

A composite medical balloon, comprising:
- a balloon including first and second tapered portions having a barrel portion therebetween, the balloon defining a balloon length extending from a first longitudinal location at a proximal end of the first tapered portion to a second longitudinal location at a distal end of the second tapered portion;
- and
- a hybrid layer adhesively attached to the balloon, the hybrid layer comprising a tube made of a first material covering the barrel portion, a first spirally wrapped ribbon made of a second material covering the first tapered portion, and a second spirally wrapped ribbon made of the second material for covering the second tapered portion;
- wherein the first material is different from the second material;
- and
- wherein none of the tube, the first spiral wrapped ribbon, and the second spiral wrapped ribbon extends along an entire length of the balloon length.
