ABSTRACT:
A catheter balloon is provided for medical dilation procedures which is formed from a polymeric composite having an enhanced integrity. The balloon comprises an expandable central body and two tapered termini positioned at opposing ends of the body which are formed from a structural layer of continuous polymeric materials characterized as biaxially oriented in the body, but not in the tapered termini. A layer of an imide-containing polymer is provided external to the structural layer of the tapered termini to coat the termini and strengthen or otherwise enhance the integrity of the termini not having a biaxial orientation. The imide-containing polymer coating may further be continuously extended to the body of the balloon. The imide-containing polymer is applied to the structural layer of the balloon, in a liquid state and heat cured over time to produce a high-integrity coating.
