Abstract
Methods for forming low profile balloons for use with a catheter by providing a polymeric tube, removing material from the outer surface of the polymeric tube around at least one of its end portions, and inflating a region of the polymeric tube between the two end portions to form the balloon. Low profile balloons having end portions with an outer diameter below 30 mils are also disclosed.
Claims17
A balloon for use with a catheter, the balloon comprising:
- an outer surface comprising a balloon material;
- two end portions having an inner diameter and an outer diameter;
- and
- a region between the two end portions, wherein the region has two transition portions leading to the two end portions, and wherein the outer surface beyond at least one of the two transition portions and near at least one of the end portions has less balloon material than the outer surface near the region between the two end portions.

A balloon for use with a catheter, the balloon comprising:
- an outer surface comprising a balloon material;
- two end portions having an inner diameter and an outer diameter;
- and
- a region between the two end portions, wherein the region has two transition portions leading to the two end portions, and wherein the outer surface beyond at least one of the two transition portions and near at least one of the end portions has less balloon material than the outer surface near the region between the two end portions, and the outer diameter of the outer surface near the at least one of the end portions being less than about 30 mils.

A balloon for use with a catheter, the balloon comprising:
- an outer surface comprising a balloon material;
- two end portions, at least one of end portions having a first inner diameter and a first outer diameter;
- and
- a region between the two end portions, wherein the region has two transition portions leading to the two end portions, wherein at least a portion of the region has a second inner diameter and a second outer diameter, and wherein the difference between the first inner diameter and the first outer diameter beyond at least one of the two transition portions is less than the difference between the second inner diameter and the second outer diameter.
