ABSTRACT:
Disclosed are an instrument for expanding a tubular organ such as a blood vessel and for keeping the tubular organ expanded for a predetermined period of time, and a catheter for mounting said instrument at a desired position within the tubular organ, said catheter being capable of moving and recovering the instrument mounted within the tubular organ. The instrument is formed of a two-way shape memory alloy and expands or shrinks in the radial direction, in accordance with changes in temperature. At least one side hole is formed at the distal end portion of the catheter, on which the instrument is detachably mounted.
