ABSTRACT:
A shock wave head for non-contact disintegration of a calculi situated in the body of a life form comprises a shock wave generator for generating a shock wave essentially in one plane, and a lens arrangement received in a shock wave tube for focussing the shock wave into an in-focus range in a target region. The lens arrangement is mounted for adjustable movement in the shock wave tube from an extended position against a stop on the shock wave tube so that the arrangement can yield in the direction towards the shock wave generator when it is contacted by a patient being treated.
