Title:
METHOD OF MANUFACTURING TUBE-LIKE STRUCTURE, AND STENT
Document Type and Number:
WIPO Patent Application WO/2010/095664
Kind Code:
A1
Abstract:
A method of manufacturing a stent (20), wherein, in the method, a stent base (10) having a side surface formed in a bellows-like shape is contained in a grinding container (4) and magnetic particles (7) are caused to flow in the circumferential direction of the stent base (10) by the effect of magnetic poles (8), which are arranged outside the grinding container (4), while abrasive particles (6) are caused to flow in the axis direction of the stent base (10), to grind the surfaces of the stent base (10) to thereby manufacture the stent (20). The method includes a first grinding step for grinding, with the inner surface of the stent base (10) covered, the exposed surface of the stent base (10) by causing the magnetic particles (7) and the abrasive particles (6) to flow, and also includes a second grinding step for grinding, with the outer surface of the stent base (10) covered, the exposed surface of the stent base (10) by causing the magnetic particles (7) and the abrasive particles (6) to flow.
