Scoring balloon with offset scoring elements
First Claim
1. A scoring balloon including a balloon portion having a balloon wall substantially even in wall thickness;
- a plurality of sets of scoring elements disposed on the balloon;
each set of scoring elements including a plurality of scoring elements arranged longitudinally in series, wherein adjacent scoring elements in the series are longitudinally spaced from one another so as to provide gaps between said adjacent scoring elements;
each set of scoring elements being radially spaced relative to the other sets of scoring elements around the balloon, wherein the scoring elements of one set are longitudinally offset relative to the scoring elements of an or each adjacent set of scoring elements and wherein the gaps between adjacent scoring elements are arranged such that they are substantially cylindrically aligned with the center of the scoring elements of an or each adjacent set.
