Abstract
The present invention utilizes a balloon with three or more folds to more evenly distribute the frictional forces on the inside of a stent during stent deployment thus improving the uniformity of stent cell expansion. Ideally one would like to have the same number of balloon folds as the number of stent cells distributed circumferentially around the stent. Matching the number of balloon folds to the number of cells of each cylindrical segment of the stent provides better size uniformity for the stent cells after they are expanded against the wall or other vessel within a human body.
