ABSTRACT:
A catheter is disclosed which is made of a single pre-shaped flexible pipe. The pipe is formed into a shape resembling a figure 4. This shape prevents the catheter from being expelled from a body cavity however it is still flexible enough to be straightened by a wire pushed through the catheter for insertion.
