  • Publication number: 20200332094
    Abstract: A composition contains a blend of a primary polymer and a secondary polymer, an additive and an adhesive. The secondary polymer is less crystalline than the primary polymer, and the additive increases the melt viscosity of the blend. The composition can be used in 3D printing to result in reduced warping of polymers during 3D printing, especially when using lower polymers, such as, HDPE and LLDPE.

  • Publication number: 20180369003
    Abstract: The present invention discloses a rolled up radially self-expanding stent comprising at least one transverse expandable member of non-shape memory alloy sheet or wire loops laminated in a polymer and rolled up in a configuration that stores elastic energy and retains flexibility, arranged on a longitudinal axis used to improve the lumen patency of non-vascular body lumens. The radial expansion of the stent is caused by unrolling of the rolled up transverse expandable member during deployment in the body lumen.
