  • Medical device balloons with improved strength properties and processes for producing same
    Patent number: 9956321
    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: Grant
    Filed: July 15, 2014
    Date of Patent: May 1, 2018
    Assignee: BOSTON SCIENTIFIC SCIMED, INC.
