Method of making absorbable microtubes and the product thereof
A method for making an absorbable microtube comprising the steps of a) extruding an absorbable polymer melt through a die to produce a molten extrudate; b) passing the molten extrudate 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...

| description | A method for making an absorbable microtube comprising the steps of a) extruding an absorbable polymer melt through a die to produce a molten extrudate; b) passing the molten extrudate 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 to produce a quenched extrudate; and c) drawing the quenched extrudate to produce a drawn tube having an outer diameter of about 4 to about 12 mil; and an absorbable microtube that is made according to this method. |
