Method and apparatus for direct laser cutting of metal stents

摘要: An improved expandable stent for implantation in a body lumen, such as an artery, and method making it from single length of tubing. The consists plurality radially cut cylindrical elements generally aligned on common axis interconnected by one or more interconnective elements, the having rectangular cross-section cut-to-cut. individual are disposed undulating pattern. is manufactured direct laser cutting metal tube using finely focused beam passing through coaxial gas jet structure to impinge working surface linear rotary velocity precisely controlled.
