Abstract
Abstract A coupling member for transmission of shock waves from a shock wave device to a patient to be treated is composed of an elastic, shape-stable material having a moist outside surface, and is preferably formed of a hydro-gel, such as a polyacrylamide gel. The material is provided with an insert which contributes to its good stability and also enables manipulation of the member. The coupling member can also include, with or without the insert, a shock wave sensor which is embedded in the material and enables checking the power and the position or center of the shock wave source relative to a predetermined point.
