| 摘要 |
This invention relates to a catheter comprising a tube-like basic body with a proximal and a distal end, at least one balloon member arranged close to the distal end, which can be expanded from a deflated state in which the balloon member has a small diameter to an inflated state in which the balloon member has a larger diameter. The catheter also comprises means for supplying a fluid under pressure to the balloon member in order to expand the latter, wherein the balloon member has, at least in the deflated state, a surface structure incorporating differences in height. <IMAGE> |
