  • Patent number: 10753023
    Abstract: Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning.

  • Patent number: 10568753
    Abstract: A method for delivering catheters, and stents composed of soft, compliant polymers through anatomical passages. These devices have a bulbous anchorage end with a diameter greater than the rest of the catheter. To facilitate implant and delivery a pusher catheter or sheath with an internal lumen larger than the outer diameter of the catheter but smaller than the outer diameter of the bulbous anchorage end. The distal end of pusher catheter or the sheath physically engages the proximal end of the bulbous anchorage end and applies an axial force to coaxially advance the catheter over a guidewire though anatomical passages. This method allows a physician to move the catheter to an anatomical site without the device exhibiting buckling due to axial force applied. Similarly, this delivery method will allow more force to be applied to the distal end of the catheter diminishing the likelihood of buckling.

  • Patent number: 9267033
    Abstract: The invention relates to a blend of one or more biodegradable polymers with one or more acrylic copolymers, for the purpose of improving the properties of the biodegradable polymer(s). The biodegradable polymer contains at least 10 weight percent of a biopolymer that is in less than ideal condition for processing. The “compromised” biopolymer may be undried biopolymer, may have a heat history (be “reprocessed”, “regrind” or “recycled”), or both. The acrylic copolymer(s) are present in the blend at a level of 0.1 to 15 weight percent, based on the weight of the total blend.

  • Publication number: 20150086799
    Abstract: An organic polymer solution may include about 0.1%-30% by weight of a specific polymer having rigid rod-like molecules. These molecules may include various cores, spacers, and sides groups to ensure their solubility, viscosity, and cross-linking ability. The rigid rod-like molecules are selected in such a way that they form self-assembling structures in the polymer solution, which makes it a lyotropic liquid crystal. The organic polymer solution, when properly deposited on a substrate and dried to remove solvents, forms a solid optical retardation layer of positive A-type substantially transparent to electromagnetic radiation in the visible spectral range.
