Abstract
Official abstract text for this publication.
Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stem manufacture and fabrication of a stent therefrom are disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for fabricating stent comprising: providing a PLLA tube disposed within a cylindrical mold; heating the mold and the tube to a tube deformation temperature with a heat source translating along the cylindrical axis of the mold and the tube, wherein the heat source translation rate is between 0.2-1.2 mm/s and the tube deformation temperature is 84° C.; increasing a pressure inside the tube; allowing the increased pressure in the tube to radial…
