  • Patent number: 6124007
    Abstract: A laminate balloon comprising at least two layers of separately oriented thermoplastic polymer material, which are coextensive over the body of the balloon. The two layers may be made of different polymer materials, including an underlying layer made of a low compliant, high strength polymer, such as PET, and an overlying layer of a softer and more flexible polymer material relative to the first polymer material, such as a polyester-polyether block copolymer. The balloon structures have an additive burst pressure, meaning that they are stronger than a single-layer reference balloon corresponding to the underlying polymer layer. The balloons are characterized by a combination of flexibility and surface softness which allows catheters to track down into lesions relatively easily, puncture resistance, abrasion resistance and refoldability, in addition to low compliance and high burst strength. The balloons may be prepared with generally linear or with stepped compliance profiles.

  • Patent number: 6120861
    Abstract: A tubular film for encasing food. The tubular film comprises a material which has been regenerated from a solution of cellulose in a solvent comprising carbon disulfide. The tubular material is longitudinally stretched by from 8 to 30 percent and transversely stretched by from -3 to +10 percent while wet and the stretch is maintained during drying, said transverse stretch being less than 75 percent of the longitudinal stretch, to obtain a longitudinal crystalline orientation. In general, the tubular material has a wall thickness of from 75 to 90 percent of a tubular material which is identical except for being longitudinally unstretched. The invention also includes the method for making the tubular material by stretching the tubular material while wet and maintaining the stretch during drying.
