1. A method of preparing a medical balloon, comprising:
- providing a medical balloon having an inner layer formed from a relatively soft polymer and having an outer layer formed from a relatively hard polymer; and
exposing portions of the outer layer to light from an excimer laser, the light having a fluence between 1 and 100 times larger than an ablation threshold of the outer layer, the exposed portions forming a plurality of ripple-like raised portions and recessed portions that strengthen the outer layer.

9. A method of preparing a medical balloon, comprising:
-
providing a medical balloon having an inner layer and an intermediate layer, the medical balloon being capable of receiving an outer layer over the intermediate layer; exposing portions of the intermediate layer to light from an excimer laser, the light having a fluence between 1 and 100 times larger than an ablation threshold of the intermediate layer, the exposed portions form a plurality of ripple-like raised portions and recessed portions that enhance a bonding ability of the intermediate layer; and bonding an outer layer over the intermediate layer. - View Dependent Claims (10, 11, 12, 13, 14)
