  • Patent number: 9737694
    Abstract: A method of fabrication of a medical balloon, and a balloon device useful for various medical balloon procedures, such as gastrointestinal, vascular, reproductive system, urinary system and pulmonary applications. At least two layers of a thermoplastic film are sealed at their peripheral edges and heat sealed at one or more locations inside an area enclosed by the sealed edges at predetermined locations, in one implementation of the balloon device. Such configuration enables the balloon to articulate to a desired shape upon inflation, with the desired shape being selected to accommodate a specific medical application.

  • Patent number: 8853326
    Abstract: An RF-weldable thermoplastic elastomer composition, including a thermoplastic elastomer of non-RF-weldable or poorly RF-weldable character, e.g., a styrenic copolymer/olefinic polymer blend thermoplastic elastomer, and polyol in an amount that is less than 1% by weight, based on weight of the thermoplastic elastomer, and is effective to enhance RF-weldability of the thermoplastic elastomer. The composition may also contain an antistatic ionomer, in an amount that is less than 15% by weight, based on weight of the thermoplastic elastomer. Films of such composition are usefully employed to form RF-welded film articles, such as blood bags, IV fluid bags, glucose bags, urine bags, stool bags, biological sample bags, pouches, covers, and liners.

  • Patent number: 8585676
    Abstract: A multi-lumen lay-flat tube formed of polymeric film material, e.g., polyurethane elastomer film, comprising a main tube and at least one interior tubular passage, wherein each of the at least one interior tubular passage is constituted by reentrant portions of polymeric film material forming the main tube. The multi-lumen lay-flat tube can be utilized for fabrication of a balloon catheter, or other indwelling catheter device. The multi-lumen lay-flat tube can be formed by a fabrication method including provision of superposed sheets of polymeric film material, welding the superposed sheets of polymeric film material along generally parallel, spaced-apart seam lines to form at least two passages bounded by a successive pair of such seam lines, and if desired everting the welded superposed sheets to form a main tube having at least one tubular passage therewithin.

  • Patent number: 8167859
    Abstract: A mounting structure for installation at a corporeal port opening. The mounting structure includes a reentrant tube on an exterior surface of which is disposed at least one balloon, with a proximal everted portion of the tubing extending from the distal portion of the tubing, with a gas flow passage associated with the tubing, for selective inflation of the balloon. A vacuum thermoforming process for making such mounting structure is described. The mounting structure is useful employed for anchoring of a therapeutic device such as an ostomy bag at a corresponding port of the body, with the balloon(s) of the device providing effective anchoring of the mounting structure and permitting the mounting structure to be comfortably worn by a patient during therapeutic intervention.
