Title (EN) MULTI-LAYER BALLOONS FOR MEDICAL APPLICATIONS AND METHODS FOR MANUFACTURING THE SAME
(FR) BALLONNETS A COUCHES MULTIPLES POUR DES APPLICATIONS MEDICALES ET LEURS PROCEDES DE FABRICATION
Abstract: front page image
(EN)A multi-layered balloon (120) is provided where each layer is formed such that each layer is made from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, multi-layer balloon (120) is provided with layers (100), (110) that allow for slipping, such that the balloon (120) has a very high pressure rating and toughness, yet excellent folding characteristics. Methods for producing such multi-layer balloons (120) using existing balloon forming equipment are also provided. The multi-layer balloons (120) can have alternating structural (102), (112) and lubricating layers (114), or layers with low-friction surfaces. The multi-layer balloons (120) are preferably manufactured using a variety of methods including nesting, co-extrusion, or a combination of nesting and co-extrusion. The multi-layer balloons (120) have balloon layers (100), (110) having substantially similar, or the same, high degree of biaxial orientation of their polymer molecules such that each balloon layer of the multi-layer balloon (120) will fail at approximately the same applied pressure.
(FR)La présente invention concerne un ballonnet à couches multiples (120) dans lequel chaque couche est formée de telle sorte que chaque couche est faite à partir d’un tube qui optimise l’étirement de la paroi interne, apportant ainsi une résistance maximale au ballonnet. Le ballonnet à couches multiples et pression élevée (120) est doté de couches (100), (110) qui permettent le glissement de telle sorte que le ballonnet (120) présente une capacité de pression et une résistance très élevées, tout en ayant d’excellentes caractéristiques de pliage. L’invention concerne également des procédés de fabrication de tels ballonnets à couches multiples (120) à l’aide d’un équipement existant de formation de ballonnets. Lesdits ballonnets (120) peuvent comporter des couches structurelles (102), (112) et lubrifiantes (114) alternées, ou des couches avec des surfaces à faible frottement. Lesdits ballonnets (120) sont de préférence fabriqués à l’aide d’une diversité de procédés comprenant l’emboîtement, la coextrusion ou une combinaison des deux. Lesdits ballonnets (120) comportent des couches de ballonnets (100), (110) ayant le même ou sensiblement le même degré élevé d’orientation biaxe de leurs molécules polymères de telle sorte que chaque couche dudit ballonnet (120) va échouer approximativement à la même pression appliquée.
