## Abstract

This present invention concerns a new combination of balloon catheters and formulations containing active substances that adhere to the surface of the balloon membrane. Furthermore the present invention concerns coating processes for the manufacture of these balloon catheters as well as their use in the treatment and prophylaxis of vascular diseases.

## Claims

### Claim 1

A balloon catheter including a catheter balloon with a hydrophilic or hydrophilised balloon membrane where the balloon membrane is coated with at least one active substance lying open on its surface in such a way that at least one active substance is immediately released when the catheter balloon is expanded.

### Claim at position 2

2-30. (canceled)
