Disclosed herein are intravascular systems and methods for modulating the activation of neural activity using shock wave devices. Programmable logic connectors within the interconnection blocks may be programmed to route signals between the various conductors on the device and to route signals from various logic regions on the device to the various conductors. A light source emits light to the reference grating. A first end of the conductive resilient piece is fixed on an outer surface of the housing, and the conductive resilient piece is resiliently deformed and electrically contacts the second set of metal contacts when the conductive resilient piece is pressed by a conductive component of an connector receptacle. In an embodiment, a distance sensor is coupled to the processing circuitry.
