Title:
微小損傷性の再吸収性ステント
Document Type and Number:
Japanese Patent JP2007515250
Kind Code:
A
Abstract:
A minimal injury resorbable stent comprising an oriented resorbable material drawn to a ratio about 7-350 is disclosed. The drawn materials of the present invention have tensile strength of about 50-500 MPa and Young's modulus of about 2-300 GPa. The bioresorbable stents can have cylindrical shape and optionally further comprise one or more of a solvent, plasticizer, biologically active agent and modifier. Also disclosed is a method for manufacturing a minimal injury resorbable stent. The process comprises contacting a resorbable polymer with a solvent to form a polymer mixture, extruding said polymer mixture to form an extrudate, drawing said extrudate to a draw ratio in the range of about 7-350 to form a drawn extrudate and forming said stent from said drawn extrudate. The process optionally further comprises coagulating the extrudate and annealing the extrudate and/or stent.
