Multiple beam laser system for forming stents

摘要

A system and method for precision cutting using multiple laser beams is described, The system and method includes a combination of optical components that split the output of a single laser into multiple beams, with the power, polarization status and spot size of each split beam being individually controllable, while providing a circularly polarized beam at the surface of a work piece to be cut by the laser beam. A system and method for tracking manufacture of individual stents is also provided.

1. A method for manufacturing stents using a multiple beam cutting process comprising:
splitting a laser beam into at least two laser beams; cutting a stent pattern into a tube using one of the at least two laser beams; marking the stent pattern with an identifier; sorting a batch of stents into individual stents; reading the identifier on an individual stent; marking information related to the identifier on a vial; and placing the individual stent into the marked vial.
