Abstract

A catheter balloon is provided with a balloon body that includes at least one bump provided on the outer surface of the balloon body, with the bump being made in one piece with the balloon body. The bump can include a pattern of bumps provided on the outer surface of the balloon body, with the pattern of bumps assuming one of many configurations. A method is also provided for making a balloon for use with a catheter, including providing a tubing having an outer surface and at least one longitudinal bump provided integral with and in one piece with the tubing on the outer surface, and forming a balloon from the tubing.

Claims

1. A balloon for use with a catheter, comprising a balloon body made from a material and having an outer surface, a first end, a second end and a central portion, the balloon further including a helical corrugated pattern provided on the outer surface of the balloon body and being made in one piece with the balloon body, wherein the helical corrugated pattern is provided adjacent the first and second ends of the balloon, with the central portion of the balloon being devoid of a helical corrugated pattern.

2. The balloon of claim 1, wherein the material is selected from the group consisting of PET, PE, silicone and nylon.

3. The balloon of claim 1, wherein the helical corrugated pattern is made from a material that is different from the material for the balloon body, the helical corrugated pattern being coextruded with the balloon body.

4. The balloon of claim 1, wherein the balloon has a first end, a second end and a central portion, and wherein the first and second ends have a different compliance than the central portion.

5. The balloon of claim 1, wherein the balloon is less compliant at the region of the helical corrugated pattern than at other portions of the balloon.
