  • Process for forming medical device balloons
    Patent number: 7708928
    Abstract: Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.
    Type: Grant
    Filed: December 16, 2008
    Date of Patent: May 4, 2010
    Assignee: Boston Scientific Scimed, Inc.
    Inventors: Thomas Holman, Nam H. Hoang, Jeffrey S. Lindquist, Richard Dunn, Scott Schewe, Kevin Silberg, David Parsons, Ken Xiao Kang Zhang, Afsar Ali
