<p>A stent-delivery catheter includes a balloon (20) having a generally cylindrical body and at least one narrow elastic band (30) disposed around the cylindrical body. The balloon may have several elastic bands mounted at spaced apart locations thereon. The elastic bands provide improved grip between the balloon and a stent (40) through increased friction and/or mechanical engagement with the edges (33, 37) of the bands.</p> |
