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.

Abstract translation: 一种用于形成医疗装置气囊的管形型坯。 型坯由聚合物材料形成，例如热塑性弹性体。 型坯的断裂伸长率不大于本体聚合材料的伸长率的80％。 通过改变挤出条件来控制型坯的伸长率。 从型坯制备的气球比从相同材料的常规型坯制备的气球提供更高的壁强度和/或更高的充气耐久性。
