  • MEDICAL DEVICE BALLOONS WITH IMPROVED STRENGTH PROPERTIES AND PROCESSES FOR PRODUCING SAME
    Publication number: 20180085499
    Abstract: A tubular parison for forming a medical device balloon. The parison is formed of a polymeric material, for instance a thermoplastic elastomer. The parison has an elongation at break which is not more than 80% of the elongation of the bulk polymeric material. The elongation of the parison is controlled by altering extrusion conditions. Balloons prepared from the parisons provide higher wall strength and/or higher inflation durability than balloons prepared from conventional parisons of the same material.
    Type: Application
    Filed: September 29, 2017
    Publication date: March 29, 2018
    Applicant: BOSTON SCIENTIFIC SCIMED, INC.
    Inventors: Lixiao Wang, Jeffrey S. Lindquist, Nao Pao Lee, John Jianhua Chen, Douglas A. Devens

  • Balloon cones and waists thinning methodology
    Patent number: 8357177
    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.

  • Process for forming a medical device balloon
    Patent number: 6863861
    Abstract: A balloon blowing process which involves radial expansion of an extruded tubing segment which has been subjected to a stretching step prior to radial expansion, the process utilizing an internal pressure and a temperature which together cause at least a portion of the tubing to expand to an interior diameter (ID) which is greater than the interior diameter of the extruded segment prior to extrusion.
