Stent for urinary ducts is introduced into a stiff hollow shaft (such as an endoscope shaft, for example) to reduce its diameter prior to its insertion into an urinary duct

摘要

For insertion into a urinary duct, the diameter of the stent (1) - which in its nonstressed state has an olive-shaped longitudinal contour - is reduced by introducing it into a stiff hollow shaft such as an endoscope shaft (3), for example.
