  • Patent number: 11456476
    Abstract: The present invention relates to a roll construction of laminated material that inhibits delamination of the polymer layer from a backer film upon unwinding of the roll construction. Particularly, aspects of the present invention are directed to a roll construction of laminated material prepared by a process that includes providing the laminated material having an ion-exchange resin layer, a release film, and a base layer, and feeding the laminated material to a roller to generate the roll of the laminated material. The laminated material is fed to the roller such that a first layer of the laminated material wound around the core includes the inner surface of the base layer of the first layer contacting an outer surface of the core.

  • Patent number: 11412609
    Abstract: The present disclosure is flexible and stretchable conductive articles that include a printed circuit and a stretchable substrate. The printed circuit contains an electrically conductive trace. The electrically conductive trace may be positioned on the surface of or be imbibed into the pores through the thickness of a synthetic polymer membrane. The synthetic polymer membrane is compressed in the x-y direction such that buckling of the membrane occurs in the z-direction. Additionally, the synthetic polymer membrane may be porous or non-porous. In some embodiments, the synthetic polymer membrane is microporous. The printed circuit may be discontinuously bonded to the stretchable substrate. Advantageously, the flexible, conductive articles retain conductive performance over a range of stretch. In some embodiments, the conductive articles have negligible resistance change when stretched up to 50% strain. The printed circuits may be integrated into garments, such as smart apparel or other wearable technology.

  • Patent number: 11375988
    Abstract: The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder includes two sides connected by a central tube. In some embodiments, the occluder is formed from filaments that are joined together to define a substantially cylindrical form with openings defining struts. Upon the application of force, the struts deform into loops. The loops may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. The occluder further includes a catch system that maintains its deployed state in vivo. When the occluder is deployed in vivo, the two sides are disposed on opposite sides of the septal tissue surrounding the aperture and the catch system is engaged so that the occluder closes the aperture.

  • Patent number: 11380927
    Abstract: Embodiments are directed to composite membranes having: increased volume of the microporous polymer structure relative to the total volume of the PEM; decreased permeance and thus increased selectivity; and lower ionomer content. An increased amount of polymers of the microporous polymer structure is mixed with a low equivalent weight ionomer (e.g., <460 cc/mole eq) to obtain a composite material having at least two distinct materials. Various embodiments provide a composite membrane comprising a microporous polymer structure that occupies from 13 vol % to 65 vol % of a total volume of the composite membrane, and an ionomer impregnated in the microporous polymer structure. The acid content of the composite membrane is 1.2 meq/cc to 3.5 meq/cc, and/or the thickness of the composite membrane is less than 17 microns. The selectivity of the composite membrane is greater than 0.05 MPa/mV, based on proton conductance and hydrogen permeance.

  • Patent number: 11357611
    Abstract: A stent graft including a stent having a wall having at least one opening, an outer surface, and an inner surface and a covering of a composite material having a least one expanded fluoropolymer membrane and an elastomer is provided. The cover can be used to cover the outer and/or the inner surface of the stent. The expanded fluoropolymer membrane contains serpentine fibrils. In exemplary embodiments, the fluoropolymer is polytetrafluoroethylene. The composite material may be axially and/or circumferentially wrapped around the stent. The composite material is fold-free throughout its operating diameter range and exhibits a sharp increase in stiffness at a predetermined diameter. The stent graft can be designed to have a stop point in either a radial or axial direction. The stent graft can advantageously be implanted undersized with respect to a nominal diameter without having material infolding.
