Abstract
Medical balloons and balloon preforms are made by methods which include the step of selectively removing material from the proximal and/or distal ends of a segment. In the case of a thermoplastic material characterized by one or more glass transition temperatures, the segment may optionally be maintained at a temperature below the glass transition temperature of the segment during the material removal step.
