DIMENSIONALLY STABLE BALLOONS

摘要

A medical balloon composed of a micro-composite material which provides for radial expansion of a balloon to a predetermined extent, but which has minim al longitudinal growth during balloon inflation. The micro-composite material includes a fibril component, a matrix component,and optionally, a compatibilizer. The fibril component may preferably be liquid crystal polyme r fibers randomly scattered through out the balloon material. The liquid cryst al polymers are created by extrusion at high speed. An alternative fibril component may be PET fibers which are uniformly spaced about the balloon material and extend through out the length of the balloon material tube.
