Abstract

See full text

A tubular-organ expansion unit has a cylindrical body made of a shape memory alloy which is capable of maintaining the inside diameter of a tubular body organ. The tubular-organ expansion unit includes an X-ray contrast enhancer for improving the X-ray contrast of the tubular-organ expansion unit relative to the X-ray contrast of the tubular-organ expansion unit before the X-ray enhancer was provided on the expansion unit. In a tubular-organ expansion apparatus and a method for indwelling the tubular-organ expansion unit into a lumen of a tubular body organ, the shape memory alloy of the tubular-organ expansion unit will change its radial dimension in response to changes in temperature. The shape memory alloy may be bidirectional. The tubular-organ expansion apparatus not only includes the tubular-organ expansion unit but also comprises a catheter to which the tubular-body organ expansion unit is attached and a catheter sheath which can sheath the tubular body expansion unit and the portion of the catheter to which said unit is attached.
