¹ I hate having to handle the edge-casers, but scientists can come up with new surgical procedures (as Werner Forssmann did) and that is way for them to use a long lever.

Another example is Werner Forssmann, the inventor of cardiac catheterization """ In 1929, while working in Eberswalde, he performed the first human cardiac catheterisation.

I'd like to point you to the wikipedia article of Werner Forssmann, who performed the first cardiac catheterization.

Forssmann was nevertheless successful; he safely passed the catheter into his heart.

Another famous one was Werner Forssmann, the first doctor to perform a cardiac catheterization, who performed the operation on himself first (then walked over to the X-ray room to get a picture to prove he succeeded).
