VORRICHTUNG ZUM GERADERICHTEN VOM URETER.

摘要

This invention provides a ureter redressing device which corrects the snacking of the ureter and keeps it in a desired shape. The redressing device is prepared by implanting a shape memory member such as a shape memory alloy or a shape memory resin in a longitudinal direction in a catheter consisting of a rod-like elastic material such as silicone rubber. The catheter is equipped with heating means for heating the shape memory member. If necessary, a temperature sensor for detecting the temperature of the shape memory member may be implanted in the catheter. The catheter may be further equipped with a hollow for ease of bending, or side holes or recesses so that its tip can be bended particularly easily.
