A balloon catheter may include a multi-lumen tube having an inflation lumen and a guide wire lumen. The blower includes a deflector that deflects a portion of the air blown towards the second portion of the preform so as to prevent it from being heated up to its softening point, characterized in that the upstream end of the deflector is aerodynamically profiled. Analog and derivative compounds are produced by derivatizing one or more of the tryptamine, alkylating agent or acylating agent. The thermal control plate may have a port for passing working gas from one side of the thermal control plate to the other. The characters are then arranged in a predetermined order to form a region character string. A detector detects whether a predetermined copy preventing signal exists within the signal played by the play unit.
