摘要: The present invention provides a method of making zero-fold dilatation balloon. Typically, the includes: providing tubular parison comprising polymeric material; source heat and pressure for forming balloon pre-form; heating, stretching, expanding to form an expanded without confining size by mold wall internal surface; subjecting resultant setting process having uniform profile along its entire length in deflated state.
