  • Balloon mold design
    Patent number: 8535597
    Abstract: A catheter balloon molding system designed to facilitate multi-expansion step balloon forming processes using a segmented mold form. A multi-mating segment of the mold form, defining one end portion of the balloon, is retained throughout the multiple steps and the parison is kept in place in the multi-mating segment between expansion steps while the mold form is reconfigured for the next expansion step.
