摘要： 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.

摘要： An inner diameter retaining instrument for holding a predetermined expansion state of the lumen of a tubular organ such as a blood vessel, a digestive tract, or a windpipe is disclosed. This instrument is formed into a cylindrical shape or substantially cylindrical shape by a unidirectional shape memory alloy. The outer diameter of the cylindrical body at its transformation temperature (e.g., a temperature higher than a body temperature) is set to be smaller than the inner diameter of a tubular organ in which the cylindrical body is introduced. The instrument can be deformed to be radially expanded at, e.g., the body temperature or lower. As a cylindrical shape, a coil-like shape, a shape having a spiral section, a shape having a slit in its longitudinal direction, or a mesh-like shape can be arbitrarily selected.

摘要： A catheter includes a cylindrical expansion holder detachable from its distal end portion to temporarily or permanently expand and hold an inner diameter of an internal cavity of a blood vessel or any other tubular organ. The outer diameter of the distal end portion of the catheter which supports the expansion holder is much smaller than that of other catheter portions. Even if the cylindrical expansion holder is supported on the small-diameter portion, the outer diameter of the expansion holder is equal to or smaller than that of other catheter portions. The expansion holder is made of a shape memory alloy which can radially expand or contract in accordance with changes in temperature. The expansion holder can expand or contract by supplying a warm or cool solution from side holes formed in the distal end portion of the catheter and bringing this solution into contact with the expansion holder.
