Abstract
The present invention relates to catheter balloons for medical devices. In particular, the present invention provides biaxially oriented semi-compliant catheter balloons comprising acrylonitrile polymers, acrylonitrile copolymers, and acrylonitrile blends, and methods of making same. The catheter balloons provided herein exhibit relatively high tensile strength, controlled compliance, reduced tendency for pinholing, ease of coating with and of bonding to other compounds, as well as resistance to moisture.
