A METHOD OF MAKING ABSORBABLE MICROTUBES AND THE PRODUCT THEREOF

摘要

A method for making an absorbable microtube comprising the steps of a) extruding an absorbable polymer melt through a die (3) to produce a molten extrudate; b) passing the molten extrudate (14) vertically through an air gap ranging from about 0.1 to 0.5 inch as measured from the tip of the die to the surface of a liquid quenching medium (5) to produce a quenched extrudate; and c) drawing the quenched extrudate to produce a drawn tube (15) having an outer diameter of about 4 to about 12 mil; and an absorbable microtube that is made according to this method.
