Abstract: The notched Izod impact toughness and tensile elongation of poly(lactic acid) (PLA)-homopolymers are increased by about 2 to about 4 times by blending therewith a PLA-copolymer having a difunctional flexible middle segment such as a polysiloxane or a polyether from about 0.6 wt. % to about 20 wt. %.

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.

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.

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.
