1. A dilation catheter comprising:
- an elongate catheter body with at least one lumen; and
a medical balloon disposed about a portion of the elongate catheter body in fluid communication with the lumen, the medical balloon comprising;
a proximal region and a distal region;
a balloon working length intermediate the proximal region and the distal region;
a proximal working length-to-taper transition;
wherein the proximal working length-to-taper transition comprises a radius before inflation from;
0.97 to 3.3 mm when the balloon has a working length diameter of about 0.3 mm,1.8 to 4.7 mm when the balloon has a working length diameter of about 4 mm,2.4 to 6.4 mm when the balloon has a working length diameter of about 5 mm,3.5 to 8.3 mm when the balloon has a working length diameter of about 6 mm,4.8 to 10.2 mm when the balloon has a working length diameter of about 7 mm,6.2 to 11.4 mm when the balloon has a working length diameter of about 8 mm,6.7 to 13.3 mm when the balloon has a working length diameter of about 9 mm,8.1 to 15.2 mm when the balloon has a working length diameter of about 10 mm,9.1 to 17.1 mm when the balloon has a working length diameter of about 11 mm,9.9 to 19.1 mm when the balloon has a working length diameter of about 12 mm,11.2 to 22.9 mm when the balloon has a working length diameter of about 14 mm, or13.3 to 25.4 mm when the balloon has a working length diameter of about 15 mm.

Abstract
The present invention provides a medical balloon having enlarged radii, which may be disposed on a dilation catheter. The enlarged radii balloon may reduce the trauma experienced by a patient both during the procedure and when the catheter is removed from the patient. The enlarged radii may provide the deflated balloon with smoother transitions and less mechanical rigidity at the balloon transitions.

1. A dilation catheter comprising:
-
an elongate catheter body with at least one lumen; and a medical balloon disposed about a portion of the elongate catheter body in fluid communication with the lumen, the medical balloon comprising; a proximal region and a distal region; a balloon working length intermediate the proximal region and the distal region; a proximal working length-to-taper transition; wherein the proximal working length-to-taper transition comprises a radius before inflation from; 0.97 to 3.3 mm when the balloon has a working length diameter of about 0.3 mm, 1.8 to 4.7 mm when the balloon has a working length diameter of about 4 mm, 2.4 to 6.4 mm when the balloon has a working length diameter of about 5 mm, 3.5 to 8.3 mm when the balloon has a working length diameter of about 6 mm, 4.8 to 10.2 mm when the balloon has a working length diameter of about 7 mm, 6.2 to 11.4 mm when the balloon has a working length diameter of about 8 mm, 6.7 to 13.3 mm when the balloon has a working length diameter of about 9 mm, 8.1 to 15.2 mm when the balloon has a working length diameter of about 10 mm, 9.1 to 17.1 mm when the balloon has a working length diameter of about 11 mm, 9.9 to 19.1 mm when the balloon has a working length diameter of about 12 mm, 11.2 to 22.9 mm when the balloon has a working length diameter of about 14 mm, or 13.3 to 25.4 mm when the balloon has a working length diameter of about 15 mm. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method of reducing the force required to remove a dilation catheter from a conduit, comprising:
-
(a) inserting the dilation catheter through the conduit, so a medical balloon disposed on the catheter emerges from the conduit, wherein the dilation catheter includes an elongate catheter body, the medical balloon comprising; a proximal region and a distal region; a balloon working length intermediate the proximal region and the distal region; a proximal working length-to-taper transition; wherein the proximal working length-to-taper transition comprises a radius before inflation from; 0.97 to 3.3 mm when the balloon has a working length diameter of about 3 mm, 1.8 to 4.7 mm when the balloon has a working length diameter of about 4 mm, 2.4 to 6.4 mm when the balloon has a working length diameter of about 5 mm, 3.5 to 8.3 mm when the balloon has a working length diameter of about 6 mm, 4.8 to 10.2 mm when the balloon has a working length diameter of about 7 mm, 6.2 to 11.4 mm when the balloon has a working length diameter of about 8 mm, 6.7 to 13.3 mm when the balloon has a working length diameter of about 9 mm, 8.1 to 15.2 mm when the balloon has a working length diameter of about 10 mm, 9.1 to 17.1 mm when the balloon has a working length diameter of about 11 mm, 9.9 to 19.1 mm when the balloon has a working length diameter of about 12 mm, 11.2 to 22.9 mm when the balloon has a working length diameter of about 14 mm, or 13.3 to 25.4 mm when the balloon has a working length diameter of about 15 mm; (b) inflating the balloon by providing a fluid to a catheter lumen in fluid communication with the balloon; (c) deflating the balloon; and (d) applying a force to the dilation catheter, so the balloon is withdrawn through the conduit. - View Dependent Claims (10, 11)
