Title:
POLYMERIC TUBES WITH CONTROLLED ORIENTATION
Document Type and Number:
WIPO Patent Application WO/2019/049115
Kind Code:
A3
Abstract:
Methods for preparing oriented polymer tubes, such as biodegradable polymer tubes suitable for in vivo use, are provided herein. The disclosed methods provide alternatives to the typical extrusion/expansion methods by which oriented polymeric tubes for such uses are commonly produced. Advantageously, the disclosed methods can provide more homogeneous molecular orientation of crystallizable polymers within the tube walls, which can endow such polymeric tubes with enhanced strength (e.g., resistance to compression) and toughness.
