Abstract
A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer run substantially parallel to one another and substantially parallel to the longitudinal axis. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length.
Claims19
A medical balloon, comprising:
- a first fiber layer comprising a plurality of fibers running substantially parallel to one another and substantially parallel to a longitudinal axis of the balloon;
- and
- a second fiber layer including at least one fiber wound circumferentially around and at least partially along the longitudinal axis;
- wherein the first fiber layer and the second fiber layer are both embedded in a continuous matrix of thermally-weldable polymer material;
- and
- wherein the first fiber layer, the second fiber layer, and the polymer material are thermally welded to form the continuous matrix.
A medical balloon, comprising:
- a first fiber layer comprising a plurality of fibers running substantially parallel to one another and substantially parallel to a longitudinal axis of the balloon;
- and
- a second fiber layer including at least one fiber wound circumferentially around and at least partially along the longitudinal axis;
- wherein said first fiber layer and said second fiber layer are both embedded in a continuous matrix of thermally-weldable polymer material;
- and
- wherein the first fiber layer, the second fiber layer, and the polymer material are thermally welded to form the continuous matrix without an adhesive therein.
A medical balloon having a longitudinal axis, comprising:
- a first fiber layer comprising a plurality of fibers running substantially parallel to one another and substantially parallel to a longitudinal axis of the balloon;
- and
- a second fiber layer including at least one fiber wound circumferentially around and at least partially along the longitudinal axis;
- wherein the first fiber layer and the second fiber layer are both embedded in a continuous matrix of thermally-welded polymer material;
- and
- wherein the plurality of fibers of the first fiber layer have different lengths and are divided into a first group and a second group based on length.
