Abstract

A drainage catheter for draining fluids from an internal body part and a process of using the catheter wherein the catheter is subject to development of encrustations of the fluids being drained. The catheter comprises an outer flexible tubular member with a drainage lumen disposed therein. An inner flexible tubular member is slidably disposed within the outer tubular member. The inner tubular member is positioned in the outer tubular member in a predetermined location relative to the outer tubular member whereby withdrawal of the inner tubular member can cause encrustations to be broken up and removed without withdrawing the catherer from the body part being drained.
