Abstract
An electrode catheter testing device is shown which provides a practical means for determining, immediately prior to use, whether an electrode catheter is functioning properly. The device includes a pair of telescoping tube members axially displaced by means of a spring and enclosing a braided wire cylinder which defines a core for receiving the electrode end of an electrode catheter. When the spring is manually compressed, the braided wire cylinder's diameter is increased to permit insertion of the catheter. When the spring is released, the braided wire cylinder is elongated and its diameter is contracted such that the cylinder contacts the electrode rings shorting them together. Continuity to each electrode ring may then be measured electrically using a suitable instrument such as a ohmmeter.
