Claims30
A method of covering a deflated balloon positioned adjacent a distal end of a balloon catheter, the method comprising:
- positioning a first protector over a first expandable segment of the deflated balloon;
- and
- positioning a second protector over a second expandable segment of the deflated balloon, the second segment being located distally of the first segment.
In combination:
- a balloon catheter having a shaft and a deflated balloon attached to the shaft at a distal end of the shaft;
- and
- a multipart balloon protector covering the deflated balloon, the balloon protector comprising:
- a first protector covering a first expandable segment of the balloon;
- and
- a second protector covering a second expandable segment of the balloon, wherein the second segment of the balloon is located distally of the first segment.

In combination:
- an angioplasty dilation balloon catheter having a shaft with an inflatable balloon at a distal end of the shaft, the balloon being deflated and wrapped about a core which extends through the balloon;
- a first balloon protector covering a proximal expandable portion of the balloon, the first balloon protector having a first inner diameter;
- and
- a second balloon protector covering a distal expandable portion of the balloon, the second balloon protector having a second, smaller inner diameter.
