    Abstract: A processing technique and a composition which allow compositions of PBT polymers or copolymers to be formed into blow molded articles, especially medical balloons such as dilatation or stent placement balloons, from extruded tubular parisons. The process includes a longitudinal stretch step run at a temperature below the Tg of the polymeric material and a radial expansion step run at a temperature above the Tg of the polymeric material. During the longitudinal stretch step, the tubing is subjected to high internal pressure. In the composition a small amount of boric acid is added to the polybutylene terephthalate in a melt blend to give a formulation which has reduced crystallinity after extrusion and which can more readily fashioned into high strength blow molded articles than PBT by itself. Articles, which may be formed using the invention include medical device balloon articles in which the polymer consists essentially of PBT optionally blended with boric acid.

  • Patent number: 6645422
    Abstract: A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.

    Abstract: A method of forming an expandable member for a medical device, and particularly a balloon for a catheter, in which extruded tubing is first expanded in a continuous or a semi-continuous process to form expanded tubing, and then the expanded tubing is further expanded in a balloon mold to form the catheter balloon. The method generally includes expanding a long length of tubing from a first inner and outer diameter to a second larger inner and outer diameter, to form expanded tubing having an expanded intermediate diameter, and processing the expanded tubing to form a plurality of expanded intermediate diameter tube segments, each segment having a length significantly shorter than the length of the expanded tubing. One of the segments is then placed in an inner chamber of a balloon mold, and expanded in the balloon mold to form a balloon for a catheter.

    Abstract: The invention provides a highly heat-stable polyester container and a method of manufacturing the polyester container, which can be treated by retort sterilization at a high temperature after filling food, a drink or the like in the container and sealing off it, and which has superior heat stability enough to prevent deformation and whitening due to heat shrinkage in a bottom portion of the container even when treated by the retort sterilization. In the polyester container, a barrel portion and a bottom portion of the container are heat-set, and at least the bottom portion of the container has an endothermic peak on a DSC curve in the range of not lower than about 150° C. but not higher than a melting start point.

  • Publication number: 20020150703
    Abstract: A method of making a polyester container having an enhanced level of crystallinity in the sidewall while maintaining a low level of crystallinity in a thickened base portion. The container is particularly useful as a refillable container which can withstand higher caustic wash temperatures and exhibits reduced flavor carryover, or as a hot-fill container. According to the method, a sidewall-forming section of a preform is initially expanded, heated to contract and crystallize the same, and than reexpanded; a base-forming portion of the preform is shielded from the heat treatment and is expanded either before or after the heat treatment step.

    Abstract: A heat-resistant container molding apparatus and method which are compact and inexpensive and can reliably increase the crystallinity, reduce the residual stress in a container filled with a hot content such as thermally sterilized fruit juice, and prevent a thermal deformation with improved container stability at a raised temperature. The apparatus has a receiving and removing unit for receiving primary moldings obtained by blow-molding preforms and for removing final products, a heat treatment section for heating the primary moldings by bringing the primary moldings into contact with the inner wall of a heat treatment mold while pressurizing the interior of the primary moldings within the heat treatment mold, a final molding section for blow molding intermittent moldings into final products within a final blow mold, and a rotary plate, neck support fixing plate and neck support member for conveying the moldings through the receiving and removing unit, heat treatment section and final molding section.

  • Publication number: 20020041059
    Abstract: A method for forming a balloon for a dilation catheter is provided herein. The method includes the steps of: (i) positioning a tube in a preconditioned mold; (ii) expanding the tube in a preconditioned mold to form a parison; (iii) positioning the parison in a balloon mold; and (iv) expanding the parison within the balloon mold to form the balloon. Thus, the tube is initially expanded into a parison in the preconditioned mold. Subsequently, the parison is expanded into a balloon in the balloon mold. Because of this unique manufacturing process, polyester block copolymers can be formed into balloons. Some of these polyester block copolymers could not be formed into a balloon using prior art blow molding processes. The resulting balloon exhibits superior characteristics, including relatively thin and consistent walls, soft texture, low uninflated crossing profile, expansion in a predictable fashion, and good tensile strength.

  • Patent number: 6344166
    Abstract: A container molding method for reducing the amount of released acetaldehyde. The method comprises a primary blow molding step of stretch-blow-molding a preform into a primary blow-molded article; an acetaldehyde reducing step of reducing the amount of acetaldehyde released from the primary blow-molded article; and a final blow molding step of stretch-blow-molding the primary blow-molded article having a reduced amount of acetaldehyde into a final container. The primary blow molding step molds the primary blow-molded article which is larger in size than the final container and which has an average wall-thickness of a stretched barrel portion equal to or less than 0.3 mm, that is smaller than the average wall-thickness of a barrel portion of the final container. The acetaldehyde reducing step heats the thin-walled barrel portion of the primary blow-molded article at a high temperature for a relatively short time.

  • Patent number: 5792415
    Abstract: A method is provided for manufacturing a balloon for a catheter. The method comprises the steps of providing a mold having a mold cavity that generally corresponds to an intended expanded form of the balloon. Securing elements are provided at opposite ends of the mold cavity for securing end sections of a tubular parison. The end sections of the tubular parison are twisted in opposite directions with respect to each other. The end sections of the tubular parison are secured in the securing elements, the parison is heated, and a pressure differential is created between the inside and the outside of the parison to cause it to expand into a balloon against the walls of the mold cavity. The previously twisted end sections of the parison result in the balloon transition sections having spiral ridges, allowing the balloon to be folded into a small diameter.
