Abstract
A ureter correcting device for correcting meandering of a ureter and maintaining a desired shape of the ureter is disclosed. The correcting device is formed by embedding a shape memory alloy member, e.g. a shape memory alloy or resin in a catheter consisting of a rod-like elastic body such as silicone rubber along its longitudinal direction. The catheter further includes warming means for warming the shape memory member. A temperature sensor for detecting the temperature of the shape memory member may be embedded in the catheter as needed. A hollow portion may be formed in the catheter to facilitate bending of the catheter, or side holes or recesses may be formed in the distal end portion of the catheter so as to allow especially the distal end portion to be easily bent.
