A method for manufacturing an indwelling stent comprising the following
steps: preparing a substantially circular cylindrical super elastic metal pipe
which has an outside diameter suited for the part of the body in which the stent is
put, making a plurality of notches or holes in the cylindrical wall of said pipe
by removing unnecessary parts in a cylindrical wall
wherein said step of making a plurality of notches or
holes in the cylindrical wall of said pipe is performed by the following steps: making an unfinished sent of almost the shape of the finished stent by
cutting or chemically etching the unnecessary parts of said pipe, next, subjecting the
unfinished stent to a chamfering process for
removing edges and turrs of said unfinished stent, and
then, removing the thermally denaturalized portions in a periphery of said unfinished
stent which occur during said step of making an unfinished stent and coating
a biocompatible metal to said unfinished stent on which
the thermally denaturalized portions were removed.
