Zap Surgical Systems Inc.

ZAP Surgical Systems is a medical technology company specializing in advanced surgical robotics for cranial stereotactic radiosurgery (SRS). Founded in 2014 by Dr. John R. Adler, inventor of the CyberKnife system, ZAP develops the ZAP-X Gyroscopic Radiosurgery platform—a self-shielded, vault-free radiosurgery system using linear accelerator technology for precise, non-invasive treatment of brain tumors and lesions. The ZAP-X platform eliminates the need for expensive radiation bunkers, uses no radioactive cobalt sources, and features real-time dosimetry validation with dual independent gantry design to protect neurocognitive function. The company also offers the ZAP-Axon Radiosurgery Planning System (FDA and EU cleared). With global installations in leading medical institutions, ZAP expands access to high-quality, cost-effective cranial SRS in diverse clinical settings—from suburban and rural satellite locations to innovative outpatient environments.
